1. I'd get a stronger fan than you need, not really sure if the 429cfm is overkill.
2. Fan should be rated lower than the carbon filter, otherwise the fan doesn't work as well, could wear out faster, get hot.
3. Better to start with a seedling starter soil for the first week or two. I have used, however, the same potting soil throughout with success.

Good luck :jointsmile:
bigtopsfinn Reviewed by bigtopsfinn on . advice and help is much needed first grow. :rastasmoke:Will get straight to the point, need some quick answers before i go finalize the set-up.. 1. the fan im planning on buying is a 6" vortex 429cfm i belive. the reason i choose 6 "and not 4" is because i just rather be safe then sorry, if somebody wants to convince me im using too much im open to critcism.I would like to use my original thought of the 4"can fan with 4x16 odorsok.(let me know what you think). My set up is a enclosed wood box 5.5'x6x5, 6 plant setup. 400hps Rating: 5
