hey, ill be 12/12ing in a week or so. i have a 400W mh and 800W in CFLs on 8 plants. 24/0 lighting should i change them ALL to yellow spectrum lights? ive read posts recommending using a mix (yellow and white) for better results. whats the best way to go?
I have heard many times that the 400Mh is great for vegetation and 400HPS is for flowering. Its even on the write up that someone made about "USING CFL"
get a 400 hps bulb in there for flower.. and i would change over pretty much all of those cfls..use a few of the daylight bulbs but mainly the warm ones
another 12/12 question do i need to "prepare" the plant? just go straight from 24/0 to 12/12? when should i change ferts to high phosphate? before starting 12/12 or after? how much MINIMUM nitrogen and potassium should the fert have? thanks
