The Flowerpot Men 20 x 40 CELL SEED TRAY INSERTS

40 CELL LAYOUT: Features 40 individual plug cells per tray (400 total plant cells in the pack), providing an ideal setup for high-volume propagation, bedding plants, and small seed germination. REQUIRES SUPPORT TRAY: Designed purely as insert sheets to be placed inside standard full-size gravel or seed trays—these are not self-supporting standalone units. DRAINAGE HOLES: Each cell features bottom drainage holes to prevent root rot, allow healthy root aeration, and facilitate easy bottom-watering. SINGLE USE / SEASONAL PLASTIC: Made from lightweight, flexible plastic designed for quick seasonal germination and easy seedling removal ("popping out") without damaging young roots. VALUE PACK OF 20: Includes 20 insert sheets, giving you a cost-effective bulk solution for spring sowing, allotment preparation, and greenhouse propagation.
