Hallo. I have a 600w Lumatek Dimmable Digital Ballast (very nice) I'm switching to flower next week, first time grower, what bulb should I use Duel Spectrum or Red Spectrum? I currently run blue spectrum metal halide for vegging... Thanks in advance
Dual then red later in flowering. dual is a better spectrum but Generally puts out less light then a standard HPS. Sent from my LG-LS980 using Grasscity Forum mobile app
