is there such a thing as too much fluoescent?

Hey guys, i have a 5'x4' room with 2x dual 48w t12 bulb holders. is this enough fluorescent lighting for a crop that moves into a 6'x5' room with 2x 400w HPS lights? Also, how much vegetative light is too much?

thanks in advance!

too much light? only if youre burning shit with it. or if you can make more light than the sun does.

Not enough if you ask me.. t-12's are crappy. T-5's wpuld be a much better way to go..

Do T8 tubes fit into T12 lamps? I believe T8's are more efficient, but not sure

T5's are better.. More efficient, more lumens..

You are right about the T5's, they kick ass. My point was just that he already has the T12 fixtures, so if T8's would fit into them he could gain efficiency without buying new fixtures.

thanks for the input guys, so i can fit t8's in my fixture? is two fixtures enough?

thanks in advance.

If I had the extra cash. I'd build a grow room where all of the walls would be covered with fluro tubes. That would kick ass - light EVERYWHERE! The plants would love it.

Actually, I've just done a bit of reading on this and, if I understand correctly, the T8 tubes will fit but you might have to change the internal ballast, which is probably more hassle than it's worth. Check this out: http://answers.yahoo.com/question/index?qid=20090426034846AAalBwK

yeah sounds more annoying than it's worth, lol. I have mylar with fixtures about a foot away from the plants, I'll see how it works out for now, if anything i'll throw a couple cfl's in there.

you can put those cfl right on the plant dude. foot away is a waste
