Looking for rectangle tray 36''x30''x5'' flat smooth bottom needs to be strong handling 40-50 LBS
Currently our largest size trade is the 1020. We have been considering making a flood tray or ebb and flow tray but havent done so yet. However I will say that i feel confident that our 1020 could handle this kind of weight.
What is the thickness in millimeters of the trays?
It is 2mm thick.
How many trays in a pack?
There is 1 1020 tray per pack.
Will the microgreen trays fit in the 10x20 trays? Wanting to seed in the microgreen trays with holes and use the 10x20 with no holes to bottom water the microgreens during vegatative state.
The microgreen trays will fit on top of the 1020 trays. You are able to bottom water using these. You will need some extra water compared to our microgreen trays with no holes.
