ok so my current set up is 1 - 150 watt HPS on top and 4 - 2700K cfls on the side which i bought because i thought i was going to be flowering someone's plants for them. My question is will my new plants still be ok vegging under this 2700K light and the HPS or would it be worth while to go out and buy 6500K lights?

they'll be a little taller that's all, but it would be worthwhile to add the 6500 K you'll get bushier greener foliage.

If they are called "Daylight" they are 6500 K, usually come in a blue package. Philips & GE are the two who I've bought.

I have not , personally, used 2,700 K Flouro's to veg with. But nevertheless, here's my $.02 worth!

The difference between using, either, 2,700 K or 6,500 K CFL's (or Flouro's) for the purpose of either Vegging or Flowering has not been well documented - as opposed to Metal Halide vs. High Pressure Sodium lights (when used in the "wrong" stage). But I suspect that the results would be similar - that is to say that either light does work in either stage, with some degree of effectiveness. And even better, when both spectrums are combined in an optimum ratio, the effectiveness is magnified. In other words, "Yeah! Go out and buy some 6,500 K (Daylight) CFL's to go along with your HPS. That way you should kick some serious bud!

By the way - G.E. (General Electric) Daylight CFL bulbs are 6,500 K.

And then for flowering, do you switch it around? Using 4 2,700 K and 2 6,500 K? This is about the most popular ratio I've heard of for mixing CFL's, either "2-to-1" or "3-to-1", then reverse the ratio for flowering.

I'm not a great fan of CFL's only for flowering, but it seems to me that the original poster would do very well by mixing his 150 watt HPS and 4, 25 watt 6,500 K's all the way through the whole grow!

the best bud i have smoled has been grown with cfl lights and here in alaska hard to find bad herb 2700 k is almost the best light possible to bud with more red spec than an hps but light penetration is the down fall buy the cure for that is couple more cfls
