Do you keep any Blue CFLs going during Flowering?

I was wondering what most people do for flowering. All red CFLs? Even between red and blue? What's the best method?

Yes i had a few 6500K...but concentrate the light more in the red end of things for best results. There are rumours that a slight mix up of spectrums is actually good for your plant, i would have to agree.

I use both red and blue during all periods.Despite what you will hear about all the red for flower and blue for veg, I think a mix is best. Ed rosenthal states that plants finished quicker and with no noticeable differences when under a metal halite, which carries the blue spectrum.

I was wondering the same thing - ive read in a few places mixed spectrum is better than sticking with just the one.

Im actually investing in three more lights (unless anyone here says anyhting different in my journal!) and was wondering which spectrum to buy. Im planning on flowering in the next couple of weeks, and wasnt sure whether to buy all blue's now, and then replace them with reds - or just buy all reds now and mix the spectrum up a bit??

Any CFL gods wanna enlighten us all???

Sorry if i sound stupid, but are you referring to the blue colored and red colored CFLs? i saw them in Home Depot and was wondering about them...is it really that simple or am i retarded?

blue is the brighter white, or daylight sometimes called. These are useful for vegetative phase cause they tend to reduce stretching.

Red is the warmer white, or softlight sometimes called. These supposedly give out the spectrum your plant wants to produce flowers.

I'm just not sure what combination is good for flowering. I ran only blue lights during vegetative, and then switched to 5 reds and one blue.

first 2-3 weeks of flowering im using just red spectrum, then adding some blue for the latter part of flowering to add some potency and taste as iv heard

blue is supposed to stop the plant from stretching as much as it would otherwise...

I use all blue (6500K) at first. It keeps them nice and tight. Once flowering begins I use mostly red (2700). The ratio is about 3 2700K's for every 1 6500K light. I have no idea if it's correct or not, but based on what I've read it certainly seems like a plausible solution. I'm also getting some pretty decent results with this balance.

Princess, don't buy the tinted bulbs. You are looking for the Kelvin rating on the bulb. This is the specturm which the bulb emits its color. 6500K appear more blue (almost white) to both your eyes and the plant. 2700K appear reddish/orange when on. 2700K is most often the bulb used for indoor lighting of living rooms and very common at hardware stores. 6500K is a brighter looking light when turned on and is used for kitchen and outdoor applications to approximate daylight. Hope this helps.

I use the best of both worlds. Meaning read and blue spectrum Cfl's. I find this mimicks mother nature the best.

Using blue CFLs during the flowering period will stop some of the stretching plants go through during flowering.

There's some natural stretching the plant will go through, but from what I understand it's the absence of a blue spectrum that causes plants to stretch out excessively.

If you think about it, it's s no brainer. Even in the fall, during the day the sun shines bright white.

Personally I would try adding at least 20% bright white lights.

What would happen if you used all blue cfl's for the for week of flowering? Then hps for the rest of the way.
