Couple growing questions

jguy21 · Jul 19, 2009

Ok, Ive got 2 questions.

Ive decided Im going to use those new 250watt fluorescent grow bulbs. Ive found 3 different kinds, 2700k for flowering 6500k for vegetative growth, and a bulb that "supposedly" combines both bulbs in one.

My first question is should I buy both bulbs and just use the 2700k for the first phase then use 6500k for flowering. Should I use both bulbs at once or 1 at a time?

(Has anybody had any experience with
these bulbs, can I use the 2 in 1 bulb?)

Also, is it the type of light that makes the plant bud? Or does the amount of light make the plant flower?

Other way round. 6500k (blue) for veg, then 2700k (red) for flower.

Flowering is initiated by your lighting schedule (unless you are growing an auto strain, which will flower based on age). 18+ hours of light per day for veg, and 12 hours of light to initiate flowering. The light types are simply the spectrum that the plant uses most efficiently during each stage.

woops mixed those up
But yehh your right 2700k flowering 6500k veg

So the spectrums make no difference in when it flowers?

Cuz i was gonna put one of each in my grow room when i get it going

It really wouldnt hurt to run both bulbs at the same time. During vegging it is just more light. And during flowering having some of the blue spectrum helps to keep stretching down, which keeps the nodes closer together.
