I havent started my first grow yet, but your plants a way to droopy! They look like they have aids or hiv. Should name them magic johnson! JK just bein funny buy really they are droopy. other than that, the temp shouldnt be below 75(AIR TEMP) I will be growing in soil, the way GOD intended. God didnt create hydroponics! Also, check out you tube and look up the green man! He make his own hydro set up and everything. Very helpful! Also, if anyone is from texas reading this, please visit texasnorml.com and mpp.com. There is a bill going through leg. that would allow the use of marijuana for medical purposes! The only way it will happen is if enough people do there part! Even if your not from texas, you can help us out if you like! Just visit the same websites! The green man shows how to produce a qp every 2 months or so! Thanks for growing dude, everybody needs to grow!
