WeedyBoyWonder Reviewed by WeedyBoyWonder on . red or blue....light gangs?? advice plz hi all!!! when i bought my compact floro sysytem (125w hydrafarm)about a week ago the store had no more blue spectrum bulbs and they werent getting any until today. So he gave me a red spectrum for the time being. I went there to day to trade out bulbs and when i got home a little while ago i was thinking about how things are going to work out. For those who dont know i started a a new setup consisting of:a 4'x2'x2' homemade box, the light,and a 4" duct fan.I dont have too much room to grow but Rating: 5
