hey, my next run I’m going to use all rockwool. The cec with promix in smart pots is annoying to manage. Any tipsYou guys have in regards to irrigation? how lite do you let them get typically? I’m going to be starting seeds in 1 1/2 inch cubes moving them to 4 inch blocks for a portion of the veg and then into the unit slab for flower. I used two drippers per four inch block. curious about irrigation times as well as what kind a drainage slits you guys like to cut.
