a light question

i'm about to switch from veg to flower, i have 4 plants in a 2'x3'x6' space
yesterday i went from:
9 26w 6500k cfls
to :
8 26w 6500k cfl's
6 26w 2700k cfl's
3 20w 3500k cfl's

first off is this enuff, i'm not sure where i can hang additional fixtures or even if i need to. they seem healthy so far but i'm admittedly new at this.

also i know i need to change the 6500k down to a 2700k but the question is when does this become a critical change? should i do this immediately when i make the 12-12 change, or gradually as the plants show sex? should i keep some (2-3) 6500k in throught out? and any thoughts on the 3500k cfls?

thanx in advance for thoughts and suggestions

Its all good man, i hear a mix of both is good I use both 2700k and 6500k ,but yes mostly 2700k in flower and the 3500k won't do any harm but you might have to worry about heat with all them CFL's in a confined space

thanks for the input. since the 2700k's i use come in 6-packs i'll probably change 6 of the 8 6500k's to 2700k's. any thoughts on the timing of the change? i was thinking of leaving the 6500k's in until i see sex/pre-flowers then chaning gradually over the plant(s) as the develop.

another thought i had was changing the 3 3500k's and 3 of the 6500k's this will leave more of the blue-white light but will increace the lumens by 900-1200.

again i'm open to suggestions

Yeah I would keep a few 6500k in the room as my last grow when i switched i switched straight to 2700k and the plants stretched like fuck but I don't know if the 6500k would have helped but it sure keeps the internode spacing short and this won't be your last grow I assume so hold on to the 6500k's they are great for veg and also the mix might help with THC production the blue light helps this I think
