My First Indoor Grow Log

Just bought a 400w dual ballast, starting off with a 400w Cool MH; I will switch to a HPS when flowering. This in in a closet about 2' 6" by 5'. Right now just three plants in their first week but will be adding a few more in the days to come. I plan on growing to about 12" before flowering, trying to keep them short due to only having 400W. Tomorrow I will be installing an exhaust fan into the attic which will later be connected to a carbon filter (closer to flowering). I have considered topping the plants but I think I am going to hold off on this batch due to the delay in recovery. Any advise or criticism is welcome; so please give it!

a few more pics. Day one is obviously not day one of plants growth, just day one under this lighting system. Plants were seeded in veg cabinet using florescent grow bulbs.

thats a nice little set up you got there
