Would you please tell me the actual hole size on the 1020 NET POT TRAY - 18 HOLE?
Each net pot hole is 2 and 1/16 of an inch in diameter.
can you grow spinach or lettuce in the 10 by 20 microgreen trays?
You can grow spinach or lettuce seeds as a microgreen crop in the 1020 microgreen trays. You cannot grow them for transplanting like you would in a traditional 200 cell tray.
