Will 3000k work for flowering?

went to get a bunch of 2700s today for when i start vegging in a few weeks, but they didnt have any. i ended up getting a bunch of 3000ks instead. i figured a 300k difference isnt enough to change much about the way the plant flowers

will the 3000ks work for flowering?

yes, you can flower with 6500k for small yeild but a mix of the two is better so the 3000k might be a bit better for your plants.

so a mix is better than just having warm lights?

yeah, i have some 6500's i could mix in with the 3000's, but would strictly 3000s or a mixture of the two be better?

I just got my new CFL's i got 2 150w full spectrum. i think its like 6500k

and i have 2 buls that are 3000k .

would this be enough to get like one or two plants from it?

from what i've read use ~3000 minimum lumens per plant. the more the better. i havent read anything about using twice as many lumens for flowering, but i'm sure it would help either way. just read what i've said above to your questions and youll be fine light-wise.

how many lumens are your 150w putting out? are they 150 equivalents, or 150w cfls?

I do believe the cool spectrum around 6500k is best suited for vegging plants, and more of the warm spec of 2700k is needed for flowering.
