I have a growbox that will give me about a foot and half to two feet plant height. I have Pc fans, cfls, a ac charger and a computer power supply. the fans are DC so i pretty much know why the charger doesnt work. so i just bought a power supply. the problem is the power supply doesnt work either. So basically i am stuck. I need help also because i have a plant above ground in veg stage. So can some one help me please. lol
