Honestly, I don't see a difference between it and the cheap ass Chinese bulb I got with my ballast.. No difference at all. But the Ushio is better crafted..
I used the chinese bulb for 5 grows, including side by side with this Ushio... I think its all hype man.
8.75 weeks.. Yellowing up good except for one... damn thing dont want to quit..
Heres the first one down at wk8 Very potent smoke. a good 60% sativa rush with a 40% Indica kick back and relax. I only tried a 3 day dried tester from lower down and it is nice, needs to finish a cure and it will be great.
