My light housing is sealed on the bottom with a glass door and has a 6†in and a 6†out flange so I went thru it with the tubing and fan out to the carbon filter... essentially the room never climbed above 77F and the lamp housing was cool to the touch. As for yield, this is a big variable based on grow technique and my original one, was simply topping and LST. I’m now training as if it was the 2020 Olympics! The tea I watered with was worm casing steeped 24 hours and aerated with an air stone. As for current yield, it’s still yielding
The ease and convenience of super soil far exceeds the crazy cost. Eventually, as I see it, most trios of nutes makes up the difference. All I do now is a pH check on my water going in. Able to use about 1200ml without drainage every 2-3 days
