makin my 1st real grow gox

hey
im just starting to make my 1st grow box / room im making 2m long by 1.5m wide dry line walled box i have a 400 hps and 600 2 6in intake/out take fans waiting on the silencers for them and i have 2 6in desk fans and a temp/humid gage anything else i need b4 i start ?

Well I am in the process of gathering everything I need to start a room. I have 2 configurations in mind, 1 with 3 rooms, flower/mother/veg or 1 with 2 rooms flower/mothers-veg. I also plan to have a small space to start clones/seedlings. I have some diagrams drawn up see what you guys thing what one I should use. I would like to grow as much as possible, at least 15 plants flowering would be great, but whatever works the best. I was planning on growing DWC using a few big ass bins, but any other ideas would be greatly appreciated! Also not sure what size of lights to use yet. I was thinking 2 600wers in the flowering room maybe 1 600/400 in veg room. Like I said I am still putting together all the pieces so it is a work in progress. By September I hope everything will be ready to grow! Here is the 2 plan layouts I was thinking about. Any feedback would be great! Thanks!
