I have 660watts of CFL lighting for my four plants. They're 3 weeks into flowering, is this enough watts?
Thanks
it is enough watts....... but... is it enough as near natural sunlight as can be achieved? well........no...
cfl will never, and i mean never be as good as hid, i mean a kettle is 2000 watts but you would not put your plants under that would you,
i use dual spectrum 600w hps, ideal for 6-8 plants, for veg and flowering.
small fast plants are better than huge plants that take forever.
i grow my seeds/clones under cfl at 20/24 hours, after two weeks slow growing then i put them under the hps for 1 week at 18/24 hours at a height of 5 feet gradually lowering the light over seven days to 2 feet then a fast switch to 12/12 on the seventh day, and thats them flowering after three weeks,
although the plants flowering trigger will take up to a week to start, so feed them veg feed through this period and then a fast 8 week flowering grow.
