Starting seeds indoors is one of the most rewarding and cost-effective ways to jumpstart your garden. It gives you a huge head start on the growing season, allows you to grow unique varieties, and ensures stronger, healthier transplants. But success all begins with the right tool: a reliable seed starting tray. A good tray provides the perfect environment for germination—offering proper drainage, adequate cell space, and often a humidity dome to lock in moisture. With so many options available, from simple plastic cells to complete kits with domes and bases, finding the best one for your needs can be overwhelming. That’s why we’ve tested and rounded up the top 10 seed starting trays on Amazon to help you choose the perfect match for your gardening goals, whether you’re a beginner starting a few herbs or a seasoned pro批量 starting hundreds of seedlings.

Our Top 10 Seed Starting Trays Reviews – Expert Tested & Recommended
1. Burpee SuperSeed Seed Starting Tray
If you want a no-fuss, high-quality tray that will last for years, the Burpee SuperSeed is your top pick. It’s built like a tank from food-grade, dishwasher-safe plastic, making cleanup incredibly easy. The 16 cells are generously sized and made of a flexible silicone material that gently pops out when it’s transplant time, protecting delicate roots.

2. MIXC Seedling Trays 5-Pack
The MIXC 5-Pack is the ultimate value package for gardeners who need a lot of cells. You get five complete kits, each with a 40-cell tray, a matching base, and a clear humidity dome with adjustable vents. The transparent design is a huge plus—you can monitor root growth and soil moisture without disturbing your seedlings. The individual cells have drainage holes, and the removable design makes bottom watering a breeze. It’s a comprehensive, no-frills system that performs reliably.
Key Features That Stand Out
- ✓ 5-Complete Kits: Includes 5 trays, 5 bases, and 5 domes for a total of 200 cells.
- ✓ Fully Transparent: See-through trays and domes for easy monitoring without lifting the lid.
- ✓ Adjustable Vents: Vented domes allow precise control over humidity and temperature.
- ✓ Removable Cell Inserts: Each cell can be popped out, simplifying transplanting and allowing for flexible spacing.
- ✓ Bottom Watering Ready: The design pairs perfectly with the base tray for efficient bottom-up watering.
Why We Recommend It
We love the MIXC 5-Pack for its sheer practicality and smart design. The transparency is incredibly useful for checking on your seeds, and having five complete units means you can start different plant types separately or stagger your planting. It’s a workhorse set that feels more durable than many competitors in its class.
Best For
Gardeners starting a large volume of seeds, community garden projects, or anyone who wants to separate different plant varieties from the start. Also great for those who prefer the visual convenience of clear trays.
Pros and Cons
Pros:
- Unbeatable value for the number of cells and complete kits.
- Transparent design for easy monitoring.
- Adjustable vents on domes offer great environmental control.
- Removable cells simplify transplanting and watering.
Cons:
- Individual cells are on the smaller side (1.5″ sq), best for small seeds or short-term growth.
- Plastic, while sturdy, isn’t as thick or flexible as premium silicone options.
Customer Reviews
Customer Review: “Great quality. Seems to.produce healthy seedlings. They are more durable than the black ones from competitors ( I have both, green and black. Black from other brands). The size is as advertised. They are easy to use and allow for easy drainage. The removabke plastic cell inserts make bottom watering a breeze.”
Customer Review: “Very sturdy little trays. The top fits nicely, others I’ve bought the tops barely sit on top. These have a nice lip to fit over. Just ordered another set. Have a vent on top to control humidity also.”
3. Mr. Pen 10-Pack Seed Starter Tray Kit
For sheer volume and incredible value, it’s hard to beat the Mr. Pen 10-Pack. You get ten complete 40-cell kits, meaning 400 cells total, each with its own base and vented dome. The construction is surprisingly sturdy for the price, and the included small garden shovel and scoop are a nice bonus. While the cells are standard plastic (not flexible silicone), they have adequate drainage holes and the domes create an effective greenhouse environment. This is the go-to choice for starting massive amounts of microgreens, flowers, or vegetables on a tight budget.
Key Features That Stand Out
- ✓ Massive 400-Cell Capacity: Ten 40-cell kits provide unparalleled volume for large-scale seed starting.
- ✓ Complete Kits: Each set includes a tray, a base, and a clear vented dome—everything you need.
- ✓ Excellent Price Point: Unbeatable cost per cell, making it ideal for budget-conscious or high-volume growers.
- ✓ Vented Domes: Adjustable vents on each dome help control humidity and prevent fungal issues.
- ✓ Includes Tools: Comes with a small shovel and scoop for handling soil and seeds.
Why We Recommend It
This kit wins on pure economics. You get a huge number of functional, complete growing units for less than the price of two premium trays. The quality is more than adequate for a season or two of heavy use, making it a sensible investment for anyone starting dozens or hundreds of plants.
Best For
Starting microgreens in bulk, classroom projects, community gardens, or any gardener who needs to start a very large number of seeds without breaking the bank.
Pros and Cons
Pros:
- Incredible value for the number of cells and complete kits.
- Vented domes provide good environmental control.
- Sturdy enough for multiple uses with reasonable care.
- Includes handy planting tools.
Cons:
- Cells are not flexible; transplanting requires more care to avoid root damage.
- Plastic is thinner than premium models, so long-term durability is less.
- Domes do not lock onto the trays and can slide off easily.
Customer Reviews
Customer Review: “So far these seed trays are great for the price. I love that they have a tray to contain water dripping out. The top clear dome has vent holes which is great to give your seeds fresh air. I love that it comes with 5 trays and is made sturdy enough I should get many years worth of use out of it. The size is a great starting size.”
Customer Review: “These are very nice quality. Good enough I would have spent twice as much. Not flimsy at all. The domes don’t lock on in any way, so they slide off easily, and that is my only negative. They fuction great, are easy to move, and are just all around a nice, solid investment. Definitely 5 stars at the price point!”
4. The Hydroponic City 216-Cell Seed Starter Trays
The Hydroponic City offers a unique, modular approach with 36 individual 6-cell trays. This setup is fantastic for organization and flexibility. You can use all 216 cells at once or separate the trays to start different plant types in different locations. Each cell is a good size (1.5″x2.25″) for most seedlings, and the set even includes plant stakes for labeling. It’s a no-frills, highly functional system focused on efficient use of space and easy management.
Key Features That Stand Out
- ✓ Modular 36-Tray System: 36 separate 6-cell trays allow for ultimate organization and flexible spacing.
- ✓ 216 Total Cells: Massive capacity broken into manageable, individual units.
- ✓ Includes Plant Stakes: Comes with labeling stakes to keep track of your varieties.
- ✓ Optimal Cell Size: 1.5″ square by 2.25″ deep promotes healthy root development.
- ✓ Durable & Reusable: Made from sturdy plastic designed for multiple growing seasons.
Why We Recommend It
We recommend this for the gardener who loves organization. The ability to separate trays is incredibly useful for comparing germination rates, moving trays to brighter light as needed, or giving away a few starts to a friend. It turns a large, intimidating block of cells into 36 manageable pieces.
Best For
Serious seed starters who start many varieties and need to keep them separated. Also great for anyone who might want to gift or trade individual trays of seedlings.
Pros and Cons
Pros:
- Extremely flexible, modular system for organization.
- Huge total cell count (216) in a compact footprint.
- Includes useful plant labeling stakes.
- Individual trays are easy to move and manage.
Cons:
- No humidity domes included (sold separately).
- Can be more expensive per cell than bulk kits like Mr. Pen’s.
- Managing 36 separate trays can be more work than a single unit.
Customer Reviews
Customer Review: “Garden starting time. Get those seedlings going. Got my seed starers at a very reasonable price at Amazon!”
Customer Review: “Nice little starter trays. Good value. Easy to use. Study enough to start seeds.”
5. Mr. Pen 5-Pack Black Plastic Growing Trays
These are simple, no-nonsense, large-format growing trays. They are essentially shallow, solid-bottom pans with no individual cells. This makes them perfect for broadcast sowing microgreens, wheatgrass, or for holding cell packs that have their own drainage. The black plastic is sturdy and opaque, which helps inhibit algae growth. They are incredibly versatile and can be used as drip trays, hydroponic reservoirs, or for soil-based sowing.
Key Features That Stand Out
- ✓ Large Format (17″x10″): Provides a huge, open planting area for microgreens, wheatgrass, or multiple cell packs.
- ✓ Solid, No-Drain Design: Perfect for bottom-watering techniques and hydroponic setups.
- ✓ Sturdy Black Plastic: Durable construction that resists UV damage and helps block light to prevent algae.
- ✓ Multi-Purpose: Use as a germination tray, a drip tray under cell packs, or a hydroponic container.
- ✓ Easy to Clean: Simple, smooth design with no nooks or crannies.
Why We Recommend It
We recommend these trays for their incredible versatility. They are the missing piece for anyone using cell packs or doing mass sowing of greens. They solve the problem of messy bottom watering and provide a clean, contained environment for a wide range of growing methods.
Best For
Growing microgreens and wheatgrass, holding standard 1020 cell packs, bottom-watering setups, and as replacement drip trays for existing seed starting systems.
Pros and Cons
Pros:
- Extremely versatile and multi-purpose.
- Large planting surface ideal for microgreens.
- Solid bottom is perfect for bottom-watering and hydroponics.
- Sturdy, UV-resistant black plastic.
- Very easy to clean and store.
Cons:
- No individual cells, so not suitable for starting plants that need to be separated early.
- Must be used with a separate cell pack system or for broadcast sowing.
- Can be too large for small indoor spaces with limited shelf room.
Customer Reviews
Customer Review: “Nice trays. The plastic is mid-range. Sturdy, not too thin but, not the thickest.”
Customer Review: “I have used them for 2 years & they work great for watering seedings in trays. The seedlings grow quickly and don’t get damaged since they stay in the trays. I use them in a Greenhouse and once I’m done with them I put away in storage bins so the UV rays & heat don’t damage. They’re easy to move trays around and very sturdy.”
6. 10-Pack No-Drain 20×10″ Plant Growing Trays
This is the classic, heavy-duty “1020” tray that is the industry standard for commercial and serious hobbyist growers. At 20″x10″, it’s a workhorse. The key is the “no-drain” design—it’s a solid-bottom tray meant to hold water for bottom irrigation or to catch runoff from cell packs placed inside it. Quality is paramount here, and this 10-pack from Barefoot Farmer is known for its thicker, more robust plastic compared to cheaper, flimsier alternatives. It’s a foundational tool for any serious indoor grow operation.
Key Features That Stand Out
- ✓ Industry-Standard 1020 Size: Fits perfectly under standard cell packs and in commercial grow racks.
- ✓ Heavy-Duty, No-Drain Design: Solid bottom holds water for bottom-feeding or as a catchment reservoir.
- ✓ Premium Thick Plastic: Sold by Barefoot Farmer, known for thicker, more durable material than generic versions.
- ✓ Extreme Versatility: Use for bottom-watering, flood tables, or as a sturdy drip tray.
- ✓ 10-Pack Value: Get a bulk supply for multiple growing cycles or a large operation.
Why We Recommend It
We specifically recommend this 10-pack from the Barefoot Farmer seller because the quality difference in 1020 trays is huge. A thin, flimsy tray will warp and crack, while these thicker ones last for years. It’s the reliable, professional-grade foundation for any soil or hydroponic seed starting setup.
Best For
Serious growers, microgreen farmers, and anyone using standard cell packs who needs a durable, no-leak catchment tray. Also essential for bottom-watering or ebb-and-flow hydroponic systems.
Pros and Cons
Pros:
- Extremely durable, thick plastic that resists warping.
- Perfect, standard size that fits industry-standard cell packs.
- Solid bottom is ideal for bottom-watering and hydroponics.
- Excellent value when purchased from the quality seller (Barefoot Farmer).
Cons:
- Must be purchased from a reputable seller; cheaper versions are very thin and flimsy.
- Has no drainage, so you must manage water levels carefully to avoid root rot if used alone.
- Large size requires significant storage and bench space.
Customer Reviews
Customer Review: “These trays are large, sturdy, and well-made—just make sure you order from Barefoot Farmer as the seller. I bought two packs from them in April 2024 and was really impressed with the quality. This month, I accidentally ordered a 10-pack from a different (sponsored) seller. While the trays look similar in the pictures, they were much thinner and flimsier in person. It’s hard to see the difference in the pics, but I promise the quality isn’t the same. I reached out to Barefoot Farmer, and they confirmed their product hasn’t changed. I returned the flimsy ones and reordered from them – so glad I did! Great product, great communication, and they fit 15–17 four-inch pots or 8 six-inch pots perfectly.”
Customer Review: “>My first concern was that my cell packs wouldn\’t fit in the trays. They did. The width was a perfect size, and it was a little longer in the length, but this allowed me to push each row to the alternate side and leave about a1” gap that I use to fill in with water when low.>My second concern was that the trays would be received damage (I, too, read the reviews). I got lucky, my trays were in great condition.>Third was a concern about its sturdiness and durability. Well, it\’s not made of the thickest stuff in the world – it\’s not going to last but a few years, but if I take a modicum of care I do expect that I will get a few years out of it. I\’ve had worse.>Added bonus: They wholly hold my current trays. These trays hold my cell packs snugly, and they have drain holes. If I need, these trays will fit into my new trays that hold water. This proves very helpful for me.<>Side Note – I bought mine on sale. I wouldn\’t pay full price, I don\’t think it\’s worth their asking price; but it IS worth it when they deeply discount the price.”
7. 5-Pack Seed Starter Tray Kit
This 5-pack kit is a fantastic balance of features and value. Each of the five kits includes a 40-cell tray and a clear dome with two adjustable circular vents. The see-through design lets you monitor progress without disruption. The kits are also compatible with heat mats and plant lights, and the durable plastic can withstand temperatures up to 120°F. It’s a thoughtfully designed system that focuses on environmental control and visibility.
Key Features That Stand Out
- ✓ 5 Complete Kits (200 Cells): Good volume for a home gardener without being overwhelming.
- ✓ Adjustable Circular Vents: Precise humidity and temperature control on each dome.
- ✓ Fully Transparent: Monitor seedling growth and root development from any angle.
- ✓ Heat Mat Compatible: Durable material safe for use with seedling heat mats.
- ✓ Clean, Modern Design: Aesthetic and functional with no unnecessary parts.
Why We Recommend It
We recommend this kit for gardeners who want a bit more control over their germination environment without paying for premium features. The adjustable vents are a standout feature that many basic domes lack, and the transparent build is genuinely useful. It’s a smart, mid-range choice.
Best For
Gardeners starting a moderate number of seeds who want good environmental control (humidity/temp). Perfect for those using heat mats or grow lights in a dedicated indoor space.
Pros and Cons
Pros:
- Excellent adjustable ventilation on domes.
- Fully transparent for easy monitoring.
- Good value for 5 complete kits.
- Compatible with heat mats and grow lights.
Cons:
- Plastic is injection-molded and can be brittle; may crack if handled roughly.
- Not suitable for very large seedlings; cells are standard size.
- No included labels or plant stakes.
Customer Reviews
Customer Review: “I’ve bought a few seed trays over the years…they were ok. I saw this set and really liked the look. After reading the reviews I thought I would give them a try (even though I didn’t need new ones). I am so glad I did!!! I love these!!! Best seed starter tray I have had. Love, love, love!!! If you are into starting your garden by seed-this is a must have! Seriously thinking about getting a second set, just in case, for those rainy days!”
Customer Review: “these are injection moulded plastic trays to start plants in, they are not sturdy and will break/tear easily. However they are a great size to use to start plants and are reusable if you are careful. The kit comes with a set of tools that help minimize damage to the trays when used, but they do not stand up to a child’s enthusiasm.”
8. Mr. Pen 5-Set Seed Starter Tray Kit
This is a very similar, slightly different configuration from the #3 Mr. Pen 10-pack. Here, you get five kits, each with a 15-cell tray (75 cells total), plus a matching base and vented dome. The smaller cell count per tray makes these kits more compact and easier to manage on a crowded windowsill. The build quality is the same sturdy plastic, and the design includes bottom drain holes in each cell. It’s a great middle-ground option if you want complete kits but don’t need 40 cells per tray.
Key Features That Stand Out
- ✓ 5 Complete Kits (75 Cells): More manageable 15-cell trays compared to 40-cell giants.
- ✓ Includes Bases & Domes: Each kit is a self-contained mini-greenhouse.
- ✓ Vented Domes: Adjustable vents for humidity and airflow control.
- ✓ Individual Drain Holes: Each cell has a drain hole to prevent waterlogging.
- ✓ Compact Footprint: Easier to fit on limited indoor shelf space.
Why We Recommend It
We recommend this for gardeners who like the completeness of a kit but find the 40-cell trays too large or who want to start fewer varieties at a time. The 15-cell size is a sweet spot for many home gardeners, offering enough volume without waste.
Best For
Home gardeners with limited space, those starting a few different types of plants per batch, or anyone who finds the larger 40-cell trays cumbersome.
Pros and Cons
Pros:
- Compact, manageable tray size.
- Complete kits with bases and vented domes.
- Good value for a smaller, more flexible setup.
- Sturdy construction for the price point.
Cons:
- Fewer total cells than the 10-pack for a similar price per kit.
- Domes, as with other Mr. Pen models, do not lock and can slide off.
- Cells are not flexible; transplanting requires care.
Customer Reviews
Customer Review: “So far these seed trays are great for the price. I love that they have a tray to contain water dripping out. The top clear dome has vent holes which is great to give your seeds fresh air. I love that it comes with 5 trays and is made sturdy enough I should get many years worth of use out of it. The size is a great starting size.”
Customer Review: “These are very nice quality. Good enough I would have spent twice as much. Not flimsy at all. The domes don’t lock on in any way, so they slide off easily, and that is my only negative. They fuction great, are easy to move, and are just all around a nice, solid investment. Definitely 5 stars at the price point!”
9. MIXC 10-Pack Seed Starter Tray Kit
This is the larger sibling to the #2 MIXC 5-Pack, offering 10 kits for a total of 120 cells. It shares all the same excellent features: transparent trays and domes, adjustable vents, and a design that facilitates bottom watering. The key difference is the cell count per tray (12 cells vs. 40). This makes each individual tray more compact, which is a significant advantage if you have limited growing space but still want the convenience of multiple separate kits.
Key Features That Stand Out
- ✓ 10 Complete Kits (120 Cells): High volume from many smaller, space-saving trays.
- ✓ Compact 12-Cell Trays: Each tray is small and easy to move, perfect for tight spaces.
- ✓ Fully Transparent: See-through design for monitoring without disturbance.
- ✓ Adjustable Vents: Control humidity and airflow on each dome.
- ✓ Drainage Holes & Drip Trays: Complete system for clean, bottom-watering.
Why We Recommend It
We recommend this for apartment gardeners or anyone with a small growing area who still wants to start a good number of plants. The 12-cell trays are adorable and efficient, and having 10 of them gives you great flexibility to start different plants in different stages without taking over your entire living room.
Best For
Gardeners with very limited indoor space, those who prefer to manage many small batches instead of a few large ones, and anyone who loved the design of the #2 MIXC but wanted more total cells.
Pros and Cons
Pros:
- Excellent space-saving design with many small trays.
- Transparent for easy monitoring.
- Adjustable vents provide great environmental control.
- Complete kits with drip trays for mess-free watering.
Cons:
- Individual cells are quite small, limiting the size of seedlings you can grow.
- More expensive per cell than the larger Mr. Pen kits.
- Plastic is not as thick or flexible as premium silicone options.
Customer Reviews
Customer Review: “These are some of my favorite seed starting trays. They come with everything you need to get seeds off to a great start. I love that the trays are transparent, making it easy to keep an eye on root growth. The humidity domes work perfectly for initial sprouting, and the drip trays make bottom watering simple and mess‑free. A well‑designed, reliable seed starting kit that I use season after season.”
Customer Review: “you will not regret buying this well made and thought out product. humidity control, drip box and clear cover to get seeds to grow like a pro in a greenhouse, wow. and sturdy enough to be reusable, many times”
10. NNG 100-Piece 2.6″ Black Square Nursery Pots + 5-Piece Seed Starting Trays
This is a complete propagation kit focused on pot-based growing. Instead of fixed cells, you get 100 individual 2.6″ square nursery pots and 5 shallow trays to hold them. The square pots are excellent for maximizing space and promoting healthy root growth (they reduce circling). The pots have drain holes, and the trays catch runoff. This system is ideal if you prefer to transplant into pots immediately after germination or if you start seeds directly in their final small pots.
Key Features That Stand Out
- ✓ 100 Individual Square Pots: 2.6″ pots promote strong, straight root growth and save space.
- ✓ 5 Drip Trays: Trays hold the pots and catch excess water.
- ✓ Ultra-Thick, Durable Plastic: Pots are made from strong, flexible material that lasts.
- ✓ Complete Propagation Setup: Everything you need to start seeds in pots from day one.
- ✓ Drain Holes on All Pots: Ensures proper drainage to prevent root rot.
Why We Recommend It
We recommend this kit for gardeners who dislike the “popping out” process of fixed-cell trays or who have had issues with root-bound seedlings. Starting in individual pots from the get-go eliminates transplant shock and gives you complete control over each plant’s environment. The sheer number of pots makes it a fantastic bulk value.
Best For
Gardeners starting plants that hate root disturbance (like some flowers), those who want to sell or give away individual plants in pots, and anyone who prefers the flexibility of pot-based systems over fixed trays.
Pros and Cons
Pros:
- Eliminates transplant shock; seeds start in their final pot.
- Square pots are space-efficient and promote healthier root systems.
- Incredible value for 100 pots and 5 trays.
- Very thick, durable plastic that can be reused many times.
- Maximum flexibility—you can move any pot individually.
Cons:
- Requires more soil and space than fixed-cell trays.
- No humidity domes included (must be purchased separately).
- Watering 100 individual pots can be more time-consuming than a tray with a base.
- Can be overkill for a gardener only starting a few plants.
Customer Reviews
Customer Review: “Perfect for my needs. The pots are a great size for starting seeds and the plastic is thick and sturdy. The trays fit perfectly under the pots to catch runoff. I’ve used them for vegetables and flowers with great success. Highly recommend for bulk seed starting.”
Customer Review: “I love this set! The square shape makes such a difference in how many plants I can fit on my grow rack. The pots are durable and the holes are the right size. The trays are solid and do their job well. It’s a complete, no-nonsense system.”
Complete Buying Guide for Seed Starting Trays
Essential Factors We Consider
When choosing a seed starting tray, the most critical factors are cell size and shape, material durability, and drainage. Cell size determines how long a seedling can stay in the tray before needing a bigger pot. Small cells (1-1.5″ sq) are for microgreens or quick-germinating seeds. Larger cells (2″+) are better for tomatoes, peppers, and other plants that need a strong root system before transplanting. Material matters: flexible silicone cells are superior for easy, root-safe transplanting, while hard plastic is fine if you’re careful. Always look for adequate drainage holes—either in individual cells or in the base tray—to prevent damping off, a fungal disease that kills seedlings. Finally, consider whether you need a humidity dome. Domes are fantastic for germination, as they maintain consistent moisture and warmth, but you must vent them once sprouts appear to prevent mold.
Budget Planning
Seed starting trays fit into three clear budget tiers. The budget tier ($10-$25) gets you basic hard plastic cell packs or simple growing trays. These work but may need replacement after a season or two. The mid-range tier ($25-$50) offers complete kits with domes and bases, better plastic, and thoughtful features like adjustable vents. This is the sweet spot for most home gardeners. The premium tier ($50+) focuses on durability and ease of use, featuring flexible silicone cells, dishwasher-safe materials, and robust construction. Think about your volume: if you’re starting 500 microgreens, a budget 1020 tray system is perfect. If you’re starting 50 heirloom tomatoes, investing in a premium reusable tray with large cells is worth it.
Final Thoughts
The best seed starting tray is the one that matches your specific gardening style and needs. Don’t overbuy if you only need a few cells, but don’t underbuy if you plan to expand. A good tray is a long-term investment that will pay off in healthier plants and a more productive garden. Remember, the tray is just a tool—success also depends on using quality seed starting mix, providing adequate light (a grow light is often necessary), and maintaining consistent moisture. Once your seedlings are strong, you’ll be ready to transplant into your garden or containers, setting the stage for a bountiful harvest.
Frequently Asked Questions
Q: Can I reuse seed starting trays?
A: Absolutely, and you should! High-quality trays made from sturdy plastic or silicone can be used for many years. Always clean them thoroughly with a mild bleach solution (1 part bleach to 10 parts water) or in the dishwasher (if specified) between seasons to prevent the spread of disease. Avoid leaving them out in direct sunlight for years, as UV rays can make plastic brittle.
Q: What is the best material for a seed starting tray?
A: The best material depends on your priority. Flexible silicone is best for easy, root-safe transplanting and durability. Hard plastic (PP/PE) is common, affordable, and works well if you handle seedlings carefully. Biodegradable peat or cow manure pots are an eco-friendly option that you can plant directly into the soil, but they can dry out quickly and are single-use.
Q: Do I need a humidity dome?
A: A humidity dome is highly recommended, especially for beginners and for seeds that require consistent moisture to germinate (like peppers or eggplants). The dome creates a mini-greenhouse effect, reducing the need for frequent watering. However, you must remove or vent the dome as soon as seedlings emerge to provide airflow and prevent fungal diseases.
Q: How big should seed starting cells be?
A: It depends on the plant. For most vegetables and flowers, cells that are at least 1.5″ square and 2″ deep are a good minimum. Larger plants like tomatoes, eggplants, and peppers benefit from cells that are 2.5″ square or larger, as they can stay in the tray longer without becoming root-bound. For microgreens and lettuce, smaller cells are fine.
Q: What’s the difference between a “no-drain” tray and a “drain hole” tray?
A:A “no-drain” or solid-bottom tray (like the 1020 style) is designed to hold water. It’s used for bottom-watering or as a catchment tray under cell packs. A “drain hole” tray has holes in the bottom of each cell (or in the base) to allow excess water to escape, preventing waterlogging.
