Don’t beat yourself down cause only a arrogant or blind grower would say a master or they can run their room without mistakes . Biggests thing I learned was keep your eyes open to mistakes and non efficient and correct them , meaning always even when the room is running smooth to look for mistakes and errors . I like to construct my grow plan and rooms tough and simple so they do work . I noitice when people make their rooms with too many bells and whistles it only only takes one mistake too ruin ya . Keep it simple and make sure it’s 100%
