It’s not hard. It’s really easy. All this talk about temps and root rot is real but it’s all FUD. You are going to be fine and grow some nice bud.

In my house (1800 sq ft) with my large family (wife and 5 young kids) the average ppm is over 1000 with the low being 900 and high being about 1500 ppm I have 2 4×2 tents in my master bedroom. I regularly check co2 and it’s always over 1000ppm even in the tents. Both tents fully circulating air with inline intake and exhaust fans.
