I think you got your sights set a bit high dude, why don't you just get a plant to live till it gives up its smoke, then every improvement you make will be made because of an experience that you had in your space and conditions, not a bunch of advice from growers who use different styles of growing and whose advice may differ or even contradict each other.
Only U can determine your growing style.
yea i dont think ima bleach it, or powerwash it lol. I will hide it tho. i almost got all the humidity in check. jacked a 400 dollar digital de-humidifier. ive dumped 5 pails of water in two days. believe it or not, i have yet to see any mold, mainly cobwebs, spiders, and dampness which is drying up fast. i'm lining that room in mylar. added another cfl to veg 6500k. and ive noticed the soil aint drying out. after i added the dehumidifier and the box fan in the mix. plants are looking more perky, and the soil is drying better.
To bleach/disinfect that space, is the single most important bit of advice you have received in this thread. To ignore about ten people advising you to do this is absolute noobishness at it's worst.
Please, oh please, oh pretty please do not line that space with anything, to do so will beg a host of nasty flora and fauna to grow and fester into crop failure no matter how cheap or expensive or complicated you choose to grow. Not only that, but the water you are currently sucking out will be inaccessible to the dehumidifier and therefore it will be available to nurture all them nasties. Only a very thick coat of flat white paint, how cheap and easy is that?
