Hi there i had to excavate the soil from under the house to make this room I put in pics of most of the main bits that were done. I am going to run NFT and AQUAFARMS in the room so there is no soil and cuttings are by way of bubble cloner.
i did the same thing just for the cool temps under there. i ran into a few problem tho.1st was mold, the 2nd was mites. now i dont know if it was just being in cooler inviroment or what,all i now is i didnt have those problem in my place,it was two much heat in the other spot.
