Need Advice

I am in the process of building my box..6'5" tall and 46" square..I have a 400 mh with a batwing reflector. Questions..... Is my box big enough for Veg and Flower? If yes how much space for each? How big of a carbon filter do I need? How big of a exhaust fan? If any one would not mind I could use alot of advice. Thanks

Questions..... Is my box big enough for Veg and Flower? Yes, just remember your plant will most likely double in height when you switch to flowering
If yes how much space for each? 1 per square foot
How big of a carbon filter do I need? The larger you build or buy the easier it is on yoour fans
How big of a exhaust fan? Your grow area is apx 105 cubic feet. You need a fan that will IMO run 250 cubic feet a min..

No your is a small box or average grow area you only have a total of 46"X46"=2116"/144"(inches per square foot)=14.7 Square feet IMO this is the Max area for a 400 watt light.
