Question on light

Yes..you want a fan to exhaust heat out of your box and one to circulate air in the box.
depending on your box design. you can do a passive intake or install a fan for air intake.
You can use just the 2700k light to do it. But, your results will suffer.
You need at least a 5000 - 6500k CFL for Veg (Blue) and 2700k (red) for flower
 
so this will grow a shit plant?? gutted a orderd the wrong 1 what light should i add to this or should i just use that for veg then buy a red for flowerin time?
 
You need one of each if you want to get good results.
Dont cancel order. Just order another one that is 6500k

Veg with the 6500k (Blue). Then Flower with the 2700k (Red)
 
so dont cancle my blue light use for a month or so veggin then get the red 1 in & turn the blue off & use red for flowering only correct?
 
My mistake, read the E-bay link wrong in your 1st post...sorry
Right keep the order for the Blue CFL for Veg and order a RED CFL for Flowering. Then you are good.
