Hey thanks for the post and on the day I started the thread! First thing I heard about using duct fans was they will last longer by not having hot air get pulled past them...any thoughts?
Secondly I really need to learn not to water, way to anxious and bored, I love this hobby. If I run the hps with its timers and all the temps are fine in this sealed box. But if on the off cycle I keep the fresh air intake going for the box itself it pulls in the air from the basement which is at best mid 60's, its an unfinished basement in the midwest.

I put castors to make it off ground and mobile and with it being spring in three wks temps will change. I may put a small heater facing intake area of box that starts up when hps is off just trying to be safe and not burn down my place..

When people say how many watts they are using would my box then be around 900watts? one bulb is 85watt input feit cfl that should make 360watts I think and then there is one 200watt output daylight cfl and then the 400w hps. I have read your post on others threads and I am glad your the first to comment.

I have no problems with changing things or trying new stuff cause this is suppose to be fun for me and its in a safe enviroment. oh how far should my hps be from my new plants? I am going with about 25-30'' away and then keep the cfl close to them as well. I am starting out with 20 plants as to weed out the males and then start a mother or three... after i do some cutting to find out I will trim down the count.

If I lst will my height in the box be ok? its 4ft tall and about 3 something when taking the light and even less with the plants container. I am working on a extension cube to add to the top and reseal, wish i would have done it off the bat.. live and learn..
