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 its enough.My main question is that i have been told that i should start flowering when my plants are around 10-15"....what should i do, when i start flowering go buy a red spectrum bulb or do yall think it will be fine with theblue spec.ANY ADVICE i am more than thankful for. Also will be having pics soon to further help us all>

if you can fit 2x 125w in there, just use blue and red spectrum, otherwise i would go with the red one for flowering if you have to choose. or try fitting a well balanced spectrum CFL? they dont cost much and would help alot in small space like this.

good luck with your grow friend, hope everything work's out great.:thumbsup:

blue light for veg, red for flower.

thanks a lot guys i was starting to get real frustrated but yall came along and helped me out

for flowering, use them both.... check my posts about spectrums in the LED thread in the Advanced section..
