Me I had to go thru a lot of work to get my temps down for the 400w lighting system but I think it was worth it I have 4 big bushy females. I wouldnt regret getting it but I'm not going to lie it was a lot of work. 1 main reason it worked is cause the Cool Tube for the bulb. I still havent finished it but Its half done and its done half the job so if I just stop being lazy n finish it I'm pretty sure it will work 100%. for the cool tube check out the FAQs on Mellow Man or the IndoorCloset section on Turtle420 :thumbsup:
