mixing spectrums?

[Dutch Pimp]

3000k would do as well as 2700k...and 5000k would do as well as 6500k

it's not a perfect science...sometimes, you have to round off the sharp edges..:stoned:...(with floros)

Dutch Pimp Reviewed by Dutch Pimp on 06-30-2009. mixing spectrums? quick question about CFL lights. I know 6500k for veg 2700k for flower, but I see alot of logs with mixed spectrums. is this better than just switching bulbs? I've got plenty of both spectrums, I just want to know what is best for the plants. Rating: 5

would 5000k or 7300k be better for vegging? maybe a combination of the both?




and shake, i don't want to say your mistakin for sure, because i havn't looked, but cfls come in those, but i checked several manufactures and 2700k and 6500k may come in some special lamp, but for GE, philips or sylvania didn't have any in their catalog

i'm not mistaken, you just didn't look hard enough. no worries. i already have lights.

6500K. they don't make a 2700K, it was 3000K, like i stated it might be above.

good growing.

also, lookey what a little google search returned. 2700K t-8s. this was one of about 109,000 returns. so they must exist.

look a little bit harder.

[jimmy21]

those are t12's


but searching google, it looks like they do make them, for special "plant lights" but not for the 2.00 a standard lamp costs

my bad.

here.

here are some from ge if you prefer? the same ones that they sell at walmart.

hmmm, well i stand corrected. i'll have to see if my local walmart carries them. Like i said my electrical supply house couldn't get any without a special order

[headshake]

no worries man, we are all here to learn! if i get grumpy sometimes just ignore it. i'm getting old and have no patience.

not to jack the thread but i read some place that the uv rays that mh lights put out helps in the trich production when used with hps lights . i also read that the day light bulbs put out more uv than the cool white or the kitchen and bath bulbs. so my question is ; would it help to run a few 6700k cfls in with your 2700k or 3000k cfls during flower ?

[headshake]

a lot of people who use fluoros use a mixed spectrum. it is actually recommended. 75%/25% (75% 2700k, 25% 6500K).

if it's as simple as that then you could just throw in a uvb bulb. this is a highly debated topic 'round these parts.

i've got one that i'm thinking about throwing in my flower box. as soon as there is room.
