Bootstrap Farmer 72-Cell Seed Starter Trays with 1020 Flats — 5-Pack Extra-Strength Durable Reusable Combo

If you want durable, reusable trays that survive handling, stacking and multiple seasons, this combo delivers. The pack includes strong 72-cell starter trays designed to reach the bottom of a standard 1020 flat and full-size 1020 flats for propagation, making transplanting and root development easier. Materials are BPA-free and thicker than garden-center trays, so they resist cracking during transport and extended use.

How do these trays simplify starting seeds indoors?

These trays organize dozens of plants in compact, stackable formats so you can manage space and monitor germination efficiently. Their cell depth and flat compatibility let young roots grow through without becoming root-bound before transplant.

• 72 uniform cells per tray for consistent spacing and moisture control
• Cells measure 1.5" square and 2.25" deep to support root systems
• Fits snugly into 21.25" x 11.25" 1020 flats for easy handling
• Thicker plastic construction reduces breakage when moving trays

What makes these trays more durable than typical starter trays?

These are molded from extra-strength plastic that resists bending and cracking, so they stay usable season after season. Reinforced edges and a robust flat profile mean they tolerate transport, stacking and the weight of saturated media better than flimsy alternatives.

• BPA-free material formulated for longevity and repeated use
• Ribbed sides and solid rims prevent collapse under load
• Won’t crack easily during shipping or while moving seedlings
• Designed for multiple seasons, reducing replacement costs

How do these trays support healthy root and transplanting practices?

The cell depth reaches to the bottom of the flat, allowing roots to extend naturally until you're ready to transplant. Using the 1020 flats beneath promotes good drainage and root air pruning when appropriate, encouraging stronger seedlings.

• 2.25" cell depth encourages robust root development
• 1020 flats provide stable base and drainage paths for media
• Facilitates uniform watering and minimizes soggy pockets
• Easy to remove seedlings for cleaner, less-damaging transplants

How should I combine these trays with my existing seed-starting kit?

Pair each 72-cell tray with a 1020 flat for a tidy germination station. Use seed-starting mix, label each row, and place under lights or near a bright window; the tray combination fits standard heat mats and greenhouse racks.

• Use standard seed-starting mix and water from the bottom or top as needed
• Fits common humidity domes, heat mats and shelving systems
• Stackable design saves bench space and keeps seedlings organized
• Handy for nurseries, hobbyists and classroom propagation projects

Who is this for? Gardeners, small-scale growers and educators who want a resilient, reusable seed-starting system will appreciate this 5-pack. It’s especially useful for anyone who needs reliable trays that survive handling, fit standard greenhouse accessories, and support healthy root growth from sowing through transplanting.
