Hey all! I've got some girls in veg now, getting flower room ready. i have a 400 Watt HPS grow light from htgSupply, and the bulb it came with. the bulb is in white paper, and the only mention to the bulb the website provides is: Code: 400 WATT HPS LIGHT BULB This standard bulb emits 50,000 lumens with a rated life span of 24,000 hours. Features: [LIST] [*]50,000 lumens [*]24,000 hour rated life [*]mogul base [*]universal mounting position [/LIST] i want to get the best results, and read that the bulb plays a big part in that. im not sure if this bulb has any uvb output, or is the best spectrum... is there a bulb out there worth upgrading to? or is this "generic" bulb good enough? thanks for looking!
