your design is almost exactly like mine, and it works great.

I made mine using 5- 4'x8' sheets of white board $12.00 each at homedepot and 2x4s I am using a 600w digital ballast that will except MH and HPS bulbs and is alot more efficant than standard ballast's. I then sealed all seams with aluminum tape and the door with weather striping to seal all light leaks. beware of the heat though use 2 inline fans for exahust with odor filtration no real need for input fans just make 1 or 2 more holes in the bottom. Also invest in a remote thermometer with RH sensor so you can monitor the box without opening the door $30.00 to $40.00 at homedepot. I keep mine on the coffee table.

As for 2 plants. I highly recomend the SOG style for a box this size so to maximize your production vs. electricity consumption. I would put 15 to 20 plants in there for 4 weeks vegitive light on 24/7 then 8 weeks flowering 18/6 (18 hours on 6 hours off) this is my way of doing it and many may disagree with this, but with lights off your plant is not growing. The 18/6 is just enough to induce flowering while getting max light for growth during this period.

lol with your first grow and keep us updated.
Jerry Garcia 2007 Reviewed by Jerry Garcia 2007 on . Grow Box Help. Is my Setup Good? Hello, I'm in the process of doing the research to build a grow box and grow some of my Miracle plant. Attached is my general box blueprint, along with airflow plans. Will this work ok? Any other things I should keep in mind? How much power should I use for the intake and outtake fans? Also, I was thinking about putting a overhead 600w light. Would this be enough? I plan on growing 1-2 plants. Let me know! Thanks! Rating: 5
