cfl's for veg: only cool bulbs or mix?

[whitestalkslongwalks]

ok, here's the simple question: would it be better to have all, say 6500k or 5000k bulbs for veg, OR would it be best to have a mix of cool-bulbs and a few warm ones as well?

Well depends if you want to grow short dense plants or plants that are going to stretch a little more. I used nothing but 6500ks for vegging and then a mix of 3000k and 6500k for flowering.

uh, well, i'd prefer to keep them small and dense. they are northern lights; but you didn't mention which is which?

i'll use a 250w hps by itself to flower, most likely 2 plants at a time

CTT in Kelvin (K)/ Light Color/ Effect/

5000 to 8000/ Deep blue/ Encourages excellent leaf and stem growth.

4000 to 5000 / Light blue/ Encourages good leaf and
stem growth.

4000/ Neutral white/ Promotes normal growth.

3700 to 4000/ Warm neutral/ Promotes rapid growth.

3000 to 37000/ Warmer yellow neutral/ Highly active
photosynthesis for all stages of growth.

1500 to 3000/ Hot orange or red/ Promotes flowering

For cannabis, 6500k is the ideal spectrum for vegetative growth. Now this doesn't mean the plants wont grow under other specs, it just means they will do best at 6500k. in flower, cannabis does well with warm specs, 2300-2800k is ideal for maximum bud production, where as 6500k will grow shorter more dense plants with more leaves, tighter node spaces.

yeah, i've read most of that long FAQ; thanks, i think i'll be ok :)

just put in my order from insidesun for

250w hps system
2 ona blocks for odor
floramicro/grow/bloom (even though it's for hydro i hear it works well for soil?)
superthrive
rootech cloning gell
mylar

and some random crap; feeling good; gotta get a new lock for the door tomorrow, first priority, seeds should be here anyday and then i'm rolling :) i just hope i can germinate well enough and at least get a single female from my nirvana northern lights pack; odds are on my side

looks like i'll manage to keep my costs under $400 for everything for my little closet grow. now i just have to start worrying about everything else: heat, noise, odor, light leakage, blah blah blah :) but any day now the fun starts :)

wish me luck! :)
