Here is a ebb and flow crop I harvested a couple months ago. There were 8 ILGM Northern Lights autos in 4x4” rock wool blocks sitting on a 24x48x3” flood and drain table, with a 25 gallon reservoir underneath. The tray was covered with Panda film and clipped to the sides so the roots would be able to grow out into the tray. Everything was going great until 3 of the plants decided to flower 2 weeks after the others. I did my best trying to tame the canopy with a scrog net but only could do so much. The final results were great but the canopy wasn’t very pretty.
