RooTrimmer Seed Starter Trays 5-Pack 17x11x2in Green – Reusable BPA-Free Flats for Microgreens & Bottom-Watering

RooTrimmer 5 Pack Seed Starter Trays are sturdy, reusable 17" x 11" x 2" plastic flats designed to start seeds, grow microgreens, and collect drainage without leaking.

These shallow, no-drainage-hole trays give you a simple, low-mess surface for sowing seeds, propagating cuttings, and growing wheatgrass or microgreens indoors or in a greenhouse. Made from BPA-free plastic, each tray holds soil or growing medium securely and pairs with carry trays for easy transport. The set of five reduces trips back and forth between indoor and outdoor spaces and is sized to fit most propagation racks and shelving.

How do these trays make seed starting easier?

The flat, consistent surface eliminates fiddly cell trays when you need quick seeding or dense microgreen planting. Their shallow depth encourages rapid germination and makes it easy to monitor moisture. Because the trays have no built-in drainage holes, they retain water for longer—ideal when you want to bottom-water or avoid frequent refilling.

• Large 17" x 11" area fits many seedlings and propagation inserts.
• 2" depth holds ample soil for early root development.
• No drainage holes keep moisture consistent for bottom-watering setups.
• Lightweight 11.5 oz design simplifies handling and stacking.

Will these trays withstand repeated use and cleaning?

Yes — the RooTrimmer trays are molded from BPA-free plastic built for repeated cycles of planting, rinsing, and storage. Their simple geometry and smooth surfaces make them quick to clean with soap and water, and they resist warping under normal indoor or greenhouse temperatures. This durability makes them a cost-effective option compared with disposable trays.

• BPA-free material for safer long-term use around food crops.
• Smooth interior allows quick rinsing of soil and roots.
• Consistent shape resists bending and retains stacking alignment.

How do I use these trays for microgreens, wheatgrass, or seedlings?

Fill the tray with your chosen medium, scatter seeds evenly, and keep the surface moist until germination. For microgreens, sow densely and harvest within weeks; for seedlings, sow in rows or use inserts for cell-style planting. Pair a flat tray with a 24-cell carrier or placing tray to lift and move plants without spills.

• Sow microgreens thickly for a full harvest in 1–3 weeks.
• Use for wheatgrass and cat grass because of the shallow depth.
• Combine with a carry tray to transport seedlings without soil loss.

Can these trays fit into my greenhouse shelving or grow racks?

The RooTrimmer flats are sized to work with most standard propagation shelves and bench systems. Their rectangular footprint stacks neatly for storage and helps maximize shelf space. Because they’re lightweight and uniform, you can move multiple trays at once or slide them into propagation domes or humidity covers.

• 17" x 11" footprint fits common shelving and rack dimensions.
• Stackable design reduces storage footprint when not in use.
• Works under humidity domes and propagation covers for controlled germination.

Who is this for: Gardeners, urban growers, and hobbyists who want a reusable, low-maintenance tray for starting seeds, growing microgreens, and transporting seedlings. These trays suit beginners setting up a home propagation station and experienced growers who need reliable, stackable flats for greenhouse or indoor use.
