I have just made the decision to go led since my grow space is pretty small and heat is SUCH and issue. The light are arriving tomorrow, 180w ProSource UFO, and 2 45w panels, so I hope to have my room completely converted by the weekend.

Quick question, how close do you keep your 90w UFO to the top of the canopy? I've only grown w hps before and I've never brought the lights closer than 18". -DF:jointsmile:
