Im starting a new grow, but i need new lights as my old ones got smashed, im planning on buying a 250w cfl but not sure whether to get blue (6400k) or red (2700k) spectrum, i will be growing about 3-4 auto ak47 plants.

So should i buy a red or blue spectrum ?

PS: i can only afford 1 bulb, as im buying a sunmate cfl reflector which is £40, seeds £42, bulb should be about £40 and thats £20 over budget already!

:peace:

I'm workin on some lr2ak's, tried strating em with some 5500's AND 6500k's, and have noticed, the plants definately go for the 65's more than the 55's so i got all 6500's now and they love it. Just my 2 cents, but i'd setup with some 6500's at first, till they show thier hairs, then start givin em the 5500k, OR setup with both spectrums.

buy both warm 2700k and daylight 5500k i believe. More of a mix of WARM though.

I cannot afford to buy both bulbs or i would, its one or the other.

Also the only 300w bulb i can find is on fleabay, and not sure whether its a good idea to order from there.

So again, should i buy a 250w red spectrum (2700k) or a 250w blue spectrum for the whole grow?

thanks for ur input so far.
