for people who grow these responses are kinda silly.....
we can all agree the sun will be better than the cfl's, now dig this, when the morning sun comes out you bring the plants out, after the morning sun and or the temps get to high outside you bring the plants inside and put them back under the cfl's for the rest of your 18 hours- better for this method of in/outdoor is 24 hour veg, so your simply using the nice morning-early-afternoon rays and supplementing the afternoon (shitty rays and high temps) rays with cfl's...
i used to do this a few years back while i lived in san fran- one grapefruit diesel clone, using only tiger bloom in ffhf in a 5 gallon bucket yielded over 4 ounces with under 300w of cfl and flouros shared between 3 plants
roxies are a kinda of percocet usually in 15 or 30 mg's
and due to patient/dr confidentiality florida is flooded with them and junkies. people move to florida for pills like growers to california
hope this helps
oh and op as long as your temps are not extremely different inside and out you should have no problems and yield incredible. much much better than cfl's alone
to anyone else i also advise this, as long as your not worried about someone seeing them this is the best way to pump weight with cfls and its free.
