Hehe tell me about it. I grew the two tallest ones too much in veg... they are now on the side of the light instead of right underneath touching. The cab is nearly 6 ft tall, minus the electrical part at top. the calmagic is suppose to help burnt tips, bleaching and led issues. That's why calmag stuff is needed with leds I was told. No bleaching yet and she's doing decent, ill post more pics soon.
