if your growing in soil, which i assume you are, then get a moisture meter from walmart for like 5 bucks.
hmm that seems like sound advice, but i'm looking more for something like a volume of water that would be typical for each watering.
theres lots of variables man. like, what size pots? how big are your girls at each stage? what kind of ferts are you using? (maybe its not enough and the motherfuckers are thirsty) how often do you water? are you running a dehumidifier? what is your humidity level? theres probably some other shit im forgetting but hopefully you get the point. you want specifics? i cant give you specifics and i dont think anyone else can either. it depends on your environment you have and the conditions you introduce to it. get a moisture meter!..............
ha ha alright i got ya. don't know really what i was thinking, now that i understand what a water meter does for you and see that it's the obvious choice. didnt even know those things existed haha thanks a lot man
