Also don't be discouraged by the complexity of growing indoors. Its really not that complex, in fact, its really only as complex as you want it to be. Cannabis plants are very resilient, hence the name "weed". It'll take a little time to get these simple things dialed in to grow healthy plants, and from there its pretty much all just doing it better, and better and better until you're satisfied with what you've got going on. And if that doesn't happen, don't worry, cuz I don't think I'm every going to be "satisfied", its fun to always try to find things to improve upon, and I'm still nowhere near a professional or master grower. You'll enjoy it, trust me.
