Here is an ebb and flow crop I harvested a couple months ago. 8 ILGM Northern Lights autos in 4x4x3” Grodan rockwool blocks sitting on a 24x48x3” flood&drain table with a 25 gallon reservoir underneath. The tray was covered with Panda film and clipped to the sides to create darkness so the roots would be able to grow out into the tray.
