So you say this works well for you? I guess my only question would be if you have experience under similar (or the same) growing conditions, but without the home-brewed C02? I ask, because what the "con" side generally says, is that people end up crediting their home-brew C02 systems (which they say don't really produce much C02 at all) for something it didn't really do. Something to compare it to would either support or challenge that assertion.

If it does work, however, I would definately take advantage of it, if playing with the venting would not involve too big (or elaborate) a set-up. Obviously if using C02 would get me more bud in the same space, I'd be interested - since it would mean I could just use less space (since I'm really only growing for myself and "the missuss", and the odd "session" I host.)
hey babe, i'm using co2 on this run, first time. i've always gone with a fresh air intake, but this time i'm trying the other way (because my fan is WAY TOO LOUD!) i have MAJOR differences in bud density and quantity. plants are growing like they are in the tropics. i don't have any pix to compare as of now, but can probably manage to get a comparison tonite. it won't add a lb, i'm sure, but i got two to four ounces a plant before, i harvest at the end of march.

as far as a big space, my flower room is 12x16. i'm using two 5g jugs and two one gallon jugs. recipe is :

5cups water
2cups sugar
one pack yeast (highly active)

that's for a one gallon. for a larger jug, just multiply amounts by the # of gallons.... shake twice daily. in two weeks, ad one cup of sugar per gallon to each jug. these can last as long as 6 weeks (so i've been told)

my jugs fill the whole room with co2 (know how you can taste the co2 in the first sip of a coke or pepsi?) if you stay in there for a while, you'll get light headed i have NO idea what the ppm is, i just go by the "taste"

hope that helps.

also, you are MUCH better off with a 400w than with several smaller ones. trust me, a 400w is PERFECT for your space; it will light every square inch.
kindprincess Reviewed by kindprincess on . Lumens and number of lights For a fairly small grow cab situation (no bigger floor area than 2' x 3', or possibly 2.5' x 2.5'), I was debating which would be the best use of light, considering... - I don't want a lot of noise - I want to use as little power as possible - I have no immediate plans for C02 enrichment. As such, I'd like the lights to give adequate light per square foot, but not generate unnecessary heat (necessitating further climate control measures, hence more noise and more power consumption.)
