My first grow setup

I am wondering if you guys think this will be sufficient enough to lst 2 - 3 plants. ( I will be adding another 18'' fluro for flowering. ) And do you think the 3 larger planters are big enough for the whole grow.

( The box in the top left has an exhaust fan under it, there is a air intake/utility whole in the bottom, most light is kept in. )

What are you dimins. and your gonna need more light, a lot more light for 2-3. That or your not gonna get that much of a yield. You might wanna think about building some cfl lamps and reflector. It's real easy to do so. Check out Youtube and put in build cfl lamp or fixture. There is a ten minute video that is real helpful. Hope that helps for now. I'll check back later for more info. Good luck!

I'm installing another 18'' fluro for flowering. and that picture is with the lid all the way open - its alot brighter closed.

Cfls get hot and I don't want to need alot of ventilation because then I need a better fan and better filter, also cfls can burn your plant in a small space like mine. thanks for the suggestion though.
