You want a 72 cell seed tray that lets go of each seedling without crumbling the root ball, so your transplants settle in fast and keep growing. The best trays release the whole root ball intact, so transplants settle in fast. That one feature separates an easy seed-starting season from a string of tiny setbacks.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you’re sowing a windowsill herb garden or a full greenhouse run, the right 72 cell seed tray balances cell depth, drainage, and how cleanly seedlings pop out for transplanting.
Our Picks at a Glance
How To Choose The Best 72 Cell Seed Tray
Every 72 cell seed tray holds 72 seedlings, but they are not created equal. The differences that matter are how the cells release the plant, how deep the cells are, and whether the tray matches the base you already own. Here is what to check before you click buy.
Pop-out cells vs. rigid plastic
The single biggest decision is whether the cells flex. Trays with silicone bottoms let you push from underneath to pop out the whole root ball with zero tugging. Rigid plastic trays require squeezing or prying, which can tear young roots — the kind of damage that sets transplants back days.
Cell depth and drainage
Deeper cells give roots room to grow before you must transplant. Drainage holes at the bottom prevent oversaturated soil, while the base tray catches runoff. A tray with a raised rim keeps the water contained instead of spilling across your counter.
Domes and grow lights
A humidity dome (a clear plastic cover that traps moisture) keeps the soil damp while seeds germinate, so you water less often. Some kits include grow lights with timers, letting you set the light cycle automatically. Choose between a basic tray or a complete system before you start comparing.

In‑Depth Reviews
1. 6pcs Reusable Seed Starter Kit, 72 Cells Silicone
Our pick — over 4.5★ from 450+ verified ratings; the strongest balance of quality and price.
The root-friendly favorite that pops seedlings out whole, no tugging required.
This is the tray people reach for when they’re tired of damaging transplants. The silicone bottom lets you push from underneath to lift out the entire root ball in one piece — the kind of clean release that keeps young roots completely undisturbed. Each of the six trays holds 12 flexible pop-out cells, and the whole set handles up to 72 seedlings at once.
It’s built to last, too. The trays combine silicone with reinforced plastic in one piece, so they wash and reuse season after season instead of cracking like cheap single-use inserts. The corner smiley-shaped drain slots improve soil aeration and let you water from below, which cuts down on pest and disease problems. At 6 x 1 x 4.6 inches per tray, they line up neatly on a window ledge without hogging your space.
Quality is the thing that wins people over here — it’s the most-praised aspect by a wide margin. The recurring compliment is that these won’t crack, and the flexible cells make seedling removal genuinely easy. One practical note: they’re slightly unstable while you’re filling them with soil, so they work best sitting inside a support base. Buyers report they’re “durable, lasts seasons” and that they fit other brand bases, which makes them a smart first set to build your seed-starting system around.
What Makes It Pop
- Silicone bottoms release whole root balls without tearing roots
- Smiley drain slots improve drainage and allow bottom watering
- Washable and reusable for multiple seasons
The Trade-Off
- Slightly wobbly when filling, so a support base helps
- No humidity dome included for germination
Reach for this if: you want the gentlest possible transplant and plan to reuse trays for years.
Think twice if: you need a greenhouse-style dome to lock in moisture from day one.
2. VIVOSUN 6-Pack Seed Starter Trays, 72-Cell Starter Kit with Humidity Dome
The budget greenhouse kit that pairs six trays with vented domes for quick sprouting.
This six-pack is the grab-and-go answer for indoor seed starting on a budget. Each of the six 12-cell trays gets its own transparent humidity dome with an adjustable vent, so you can manage moisture and temperature without buying extra gear. The drain holes at the bottom fight overwatering and protect young roots before they ever hit the garden.
There’s real value packed into the box: 6 trays, 6 base trays, 6 humidity domes, plus a pack of garden tools and 10 labels. The base trays take the cells directly or hold six 30mm seedling blocks, giving you flexibility as your seedlings grow. Because the whole system stacks into 1 level, it stays compact on a shelf or floor stand.
Owners call these “awesome” and sturdy enough to hold up for several uses, especially when paired with a heat mat — and the trays are rated to work with heating mats operating between 0 and 120°F. A few note the lids need gentle handling, since the plastic domes are the most delicate part of the kit. If you want the most complete starter setup for the least fuss, this is the crowd-pleaser.
The Verdict: The classic all-in-one greenhouse kit at a friendly price — the vents and extra tools make it feel like a far pricier system.
3. Pattiumo 2 Packs Seed Starter Tray with Grow Lights, 72 Cells Silicone
The self-contained light kit that grows seedlings even when you’re out of the house.
This kit takes the guesswork out of indoor growing by bundling everything into one system. It includes 6 silicone trays with 12 pop-out cells each, 2 humidity domes, 4 grow lights, 2 garden tools, 10 labels, and a USB-C cable — a genuinely complete package. The base trays use upgraded PET plastic that works with heating mats running from 0 to 120°F, so you can add bottom heat for faster germination.
The defining feature is the lighting. The 8-spectrum grow lights have 4 timing settings, letting you control the light cycle while you’re away. At 16.3 x 4.5 x 7.3 inches, the whole two-pack footprint is compact enough for a studio apartment. The ventilation dial on the dome lets you tune internal humidity from 50% to 100%, matching the needs of different growth stages.
Set-up is quick, and seeds come up fast — owners note seedlings grow “like wildfire” and call it reusable and worth the price. One honest catch: lighting needs a 5-watt output charger port to power on properly, so a weak phone adapter won’t cut it. Also, a few wish the four lights could be controlled individually rather than all at once. For a first-time indoor grower who wants lights and dome in one box, this is the easiest on-ramp.
The All-In-One Appeal
- 8-spectrum grow lights with 4 timing settings
- Ventilation dial adjusts humidity from 50-100%
- USB-C powered for easy setup
Before You Buy
- Needs a 5-watt charger port to run the lights
- Lights can’t be controlled individually
Grab it if: you want lights, dome, and trays working together from day one.
Pass if: you prefer bare trays and already own a separate grow-light setup.
4. Handy Pantry Black Plastic Garden Tray Inserts, 10 Sheets
The disposable-workhorse insert that gives you 720 cells across ten sheets.
When you’re starting seeds at serious volume, this ten-sheet pack is the economical play. Each sheet carries 72 planting cells arranged in a 2×3 configuration — 12 sections of 6 cells — and the easy-tear perforations let you snap off individual groups for planting. Each cell is 2.25 inches deep and 1.375 inches square at the rim, giving seedlings a solid root column before transplant.
These are designed for single-use, which is exactly what a nursery or greenhouse needs when cycling through hundreds of starts. They’re made from BPA-free polystyrene with drain holes that promote healthy root growth. Each full sheet measures 10.5 by 21 inches, so it nests into standard 20×10 drip trays without modification.
The trade-off is honest: these are “not heavy duty but not flimsy either,” as owners put it. They’ll likely survive a couple of uses rather than years, and one report notes the large sheets can break apart if handled roughly. But for tomatoes, peppers, and mass seed-starting, the value is tough to beat — owners mention they fit Jiffy trays and hold just enough dirt to get seeds going.
The Cost-Per-Cell Call: Ten sheets of 72 cells for serious volume at a budget-friendly price — durability takes a back seat, and that’s the point.
5. Seed Starter Trays with Grow Lights, 72 Cells, 3 Lighting Modes
The three-mode light kit that sprouted seeds faster than anyone expected.
Germination speed is the headline here. Customers note seeds popping up within 2 days and plants growing fast enough to bust out of the containers weeks early. The kit includes 6 trays with 12 cells each — every cell a 1.6-inch square with 1.97-inch depth — plus 6 grow lights that give you three lighting modes to match your plants’ stage.
The light flexibility is what separates this from simpler kits. You can run white light alone, blue-plus-red for root growth, or all three combined. Blue light helps stop seedlings from getting leggy, while red light supports stems, leaves, flowering, and fruit. The transparent domes have adjustable circular vents to tune humidity from 50% to 100%, and the 3.35-inch tall cover gives seedlings room to stretch.
The catch is one owners flag honestly: the lights are great for germination but may not be strong enough to sustain seedlings long-term, with some plants eventually going leggy and dying under the LEDs. If you treat this as a germination station and move seedlings to stronger light after sprouting, it’s a stellar value. Otherwise, expect to pair it with a beefier grow light down the road.
Why It Sprouts Fast
- 3 lighting modes: white, blue+red, or all combined
- Humidity vents adjustable from 50-100%
- Seeds reported sprouting within 2 days
The Limitation
- Light intensity may not sustain seedlings long-term
- Best treated as a germination station
Choose it for: the fastest possible sprout with adjustable light color and timing.
Note: plan to move seedlings under stronger light once they’ve germinated.
6. Seed Starter Tray, 72 Cells Indoor Kit with Humidity Dome, 4in Height
The complete silicone kit with a 4.33-inch dome that doubles as a mini greenhouse.
This is the premium all-rounder that pairs flexible silicone cells with a genuinely tall lid. The 4.33-inch high dome gives seedlings real vertical space, so you can keep plants in the tray longer before transplanting. The silicone bottoms pop out the entire seedling and root system intact, which is the feature that keeps roots happy through the move to the garden.
The drainage design is more thoughtful than most. Deep grooves in the silicone bottom suck excess water away from the cells, while a raised perimeter rim keeps that water contained in the tray — no spillage across your counter. Both the PP plastic and silicone are BPA-free, and the whole thing cleans up easily after use. You get 72 cells, the dome, 10 labels, and two planting gadgets in the box.
What wins people over is the quality and how easily plants release — extraction comes out in one clean piece every time. The honest trade-off is cell size: the cells run small, so some gardeners transplant into bigger containers for root development before moving outdoors. If you’re starting dozens of seedlings and want them to come out intact, this kit earns its keep.
The Judgment: A complete, well-built kit with a tall dome and root-friendly silicone — the small cells are the only thing to plan around.
7. RooTrimmer 72 Cell Seed Trays, Thick Durable 10-Pack
The thickened-plastic workhorse that shrugs off sun and keeps its shape.
This is the tray you buy when you’re done replacing flimsy inserts every year. Made from thickened plastic, these don’t warp easily when left out in the sun, and they’re built to be cleaned and reused. Each of the 10 trays in the pack is sized for a 1020 flat — 21.26 x 11.02 inches overall with a 1.81-inch cell height — so they drop into any standard 1020 base tray.
The design is all about root health. A top drip port keeps water in balance, while bottom drip holes stop roots from sitting in saturated soil. The black color absorbs light, which helps seedling root growth when paired with a 1020 flat. Each cell is deep enough for water and nutrients without drowning the roots.
Durability is what owners praise most here, with reports that the thick construction “shouldn’t fall apart within the first year” and trays lasting several seasons of seed starting. The trade-off: cells run small, so they’re ideal for flowers but can risk root binding with bigger vegetables. One note — these run slightly smaller than standard 1020 trays, so fit is close but not always perfect under generic domes. For roses, milkweed, and flower starts, this is the dependable pick.
The Strength Story
- Thickened plastic won’t warp in the sun
- Fits standard 1020 flats
- Washable and reusable for seasons
Watch Out For
- Small cells risk root binding with larger vegetables
- Slightly smaller than standard 1020 trays
Best suited to: flower growers and anyone running many trays who wants them to last.
Skip if: you’re starting large-rooted vegetables that need bigger cells.
8. Bootstrap Farmer 72 Cell Seed Starter Tray, Extra Strength 10-Pack
The extra-strength tray that carries plants one-handed without flopping.
This is the heavyweight champion of reusable trays. Made from food-safe recycled plastic, the 72-cell tray is built to resist cracking and breaking during transport — the kind of rigidity that lets you carry a full tray with one hand without it collapsing. Owners explicitly call out that it won’t collapse when carrying plants, which is the difference between a tray you keep for years and one you replace every spring.
Each cell is 1.5 inches square by 2.25 inches deep, reaching all the way to the bottom of a standard 1020 flat. The full tray measures 21.25 x 11.25 inches, so it drops into any standard 1020 tray including Bootstrap Farmer’s own heavy-duty bases. Drain holes at the bottom keep roots from getting waterlogged.
Sturdiness is the most-praised quality by a long shot, with owners reporting multiple years of use and calling them far better than flimsy single-season trays. The only grumbles are wanting a larger drain hole and a 4-section design for easier handling. If you start seeds regularly and want to buy once, this is the long-term investment.
The Long-Haul Verdict: The sturdiest tray here, built to outlast cheaper options for years — the premium price buys real rigidity.
9. RooTrimmer 10 Pack 1020 Trays + 10 Pack 72 Cell Seed Starter Trays
The full 10-set system that pairs 72-cell inserts with no-hole 1020 bases.
This is the complete system for anyone who wants trays and bases to match perfectly, no guesswork. The bundle includes 10 cell trays and 10 solid 1020 bases with no drainage holes — the bases catch runoff while the cell trays handle drainage, a setup that supports bottom watering. Each cell tray measures 21.25 x 11 inches with a 2.36-inch height, designed to fit standard 1020 trays that are 2.5 inches deep.
The no-hole bases are built thick and rigid, with a 1.8mm thickness on a 277g bottom tray. Reviewers point out two years of heavy greenhouse use — germination, cleaning, cut flowers, fall veggies — with the trays still holding up. The package is designed to boost space, letting you dedicate a separate tray to each seed type for easy labeling and organization.
Value is the theme in owner feedback, with quality exceeding expectations for the price and cells big enough for any seed type. The honest caveats: the trays aren’t as deep as some, so you’ll transplant to bigger pots before moving plants into the garden. And one owner notes they’re less heavy-duty than much pricier trays, though perfectly adequate at a fraction of the cost. If you want a matched set that slots together, this delivers.
The System’s Strengths
- 10 cell trays and 10 bases that fit perfectly together
- Thick no-hole bases support bottom watering
- Survived 2 years of heavy greenhouse use
Keep In Mind
- Shallow cells mean transplanting before garden planting
- Not as heavy-duty as premium single trays
Go for it if: you want a complete, matched 10-set system at a sensible price.
Consider instead: deeper premium trays if you’re growing taproot-heavy plants.
Understanding the Specs
Cell Depth
Deeper cells give roots more room to grow before you must transplant. Standard 72-cell trays range from about 1.8 to 2.25 inches deep. Shallow cells work fine for quick germination, but deeper cells let you wait longer before moving seedlings to bigger pots — useful if your outdoor planting date is still weeks away.
Pop-Out vs. Rigid Cells
Silicone or flexible-bottom cells let you push from underneath to release the entire root ball in one piece. Rigid plastic cells require squeezing or prying, which can tear delicate roots. If you’re growing plants that hate root disturbance, flexible cells are worth the extra cost.
1020 Flat Compatibility
A 1020 flat is the standard tray size most greenhouses use — roughly 10 by 20 inches. Many 72-cell trays are designed to drop into these bases, which collect excess water and make the whole setup stable. If a tray doesn’t specify 1020 compatibility, check the dimensions before buying to avoid a wobbly fit.
Humidity Domes and Vents
Domes trap moisture to speed germination, turning your tray into a mini greenhouse. Adjustable vents let you control humidity as seedlings grow, usually from around 50% to 100%. A taller dome gives seedlings more vertical space, so you can keep them in the tray longer before transplanting.
