Well there is yield and then there is consistent quality. I grow every plant with individual attention all the way through. I have (with a ton of trial and many errors
finally grown consistently better flowers than I imagined I could.
Indoor is expensive no doubt. I share my heating and a/c and humidifiers/dehumidifiers with the grow and whole house. We all live at about 67- 70 degrees ambient and 45-60 % humidity. It radically lowers my costs but of course watts still add up. And it won’t work anymore if I add lights.
So I’m going to build an insulated room in my unfinished open Michigan basement or go outside.
But I will surely want light dep and then a/c and then...........
