I'm trying to find out what bulb hasn't be most lumen output and best light spectrum, I've done some research but would like to know what you guys have used before and how it worked out. I currently have a 1000w MH by Digilux and was gonna go for Thier hps as well but I know their something better out there. I need and HPS bulb for my 1000 and for my 400 watt. Starting to flower 12 Kush plants next week.
