Many factors influence the choice of a propagation tray. Item # t w TO Plastics 200 cell plug tray, 2.1”, 50/cs
Three important considerations are the propagation method 59-5040 TO Plastics 128 cell plug tray, 2”, 100/cs
being used (seed vs. cutting), the type of root system (fibrous
59-5035 TO Plastics 98 cell plug tray, 2”, 100/cs
2026 vs taproot), and where the transplant will go (greenhouse,
2027 warehouse, or field). Lettuce and herbs have more fibrous root 59-5030 • TO Plastics 72 cell plug tray, sq, 2.25”, 100/cs

Choosing a flat Flats and Carry Trays
59-3170 TO Plastics 1020 standard vacuum flat, 100/cs
Tiered production without solid shelving or ebb-flo inserts calls
for a no-hole flat to avoid drips onto the tier below. Whenever 59-3175 • TO Plastics 1020 no hole vacuum flat, 100/cs
possible, choose a flat with drain holes to avoid keeping the 53-1310 ITML 1020 no hole flat, 100/cs
