If you take apart 2 Walmart lights of America shop lights you can wire each bulb w/it's own 2bulb ballast. While over the years I have tried almost every bulb/ballast combo, the cheap stuff works just as good. Flower time is faster w/ colored bulbs red 625nm kino flow and 420nm on seperate timers (think low $ PAD). The yeild suffers. I've even tried some German 60" Osram L58W/60 in different colors. PIA. I'm thinking about a detailed instructional video. Tacman w/ flouro tubes SOG is the only way to get yeild up
I'm running 60 at a time in flower cab packed like sardines when they get top heavy they hold eachother up.
