cfl question

hey guys i have a cfl 125w 6400k for vegetation phase and 400w hps dual spectrum for bloom phase.1st i want to ask if i can flower with this 6400k cfl or its not recomended for bloom,and i have to get the 2700k one?and my 2nd question is can i use 2 cfls 1x125w 6400k and 1x125w2700k side by side for flower? i know that hps give more yield instead of cfls but it cost more electricity also.

it depends on how many plants you have. you can flower with 6400k bulbs just fine its just not an ideal spectrum, the 2700's arent very good for veg though so if choosing one bulb or the other to use throughout the whole grow go with 6400k. 2of the large 125w cfl bulbs would grow 1 or 2 plants fairly well.
My advice would be to use the cfl's for the first month or so of veg then go to the 400w hps for when you flower. the 400w would handle 4 plants quite well for flowering.

you could but imho would be counter productive the amount of yield you would get from that hps compared to the cfls would prolly make up for future costs street buys or future grows, depending on how many plants and how exactly you want to do it what strain, hydro, soil so many variables, 2 plants max use both 2700 and 6500 for veg when buds start to form 2-3 weeks in start the hps and your golden that way you only have to run for a couple weeks as opposed to 6 or 10

A 400 watt light does't cost that much to run.

about 200$ a year

Like the calculator. Thanks for the link.

you can veg and flower under either..nothing in life is perfect.
