well id definitely take advise on the grow room, ill post the specs on here and if you want you can PM me with thoughts and advice..
my grow room is going to be my basement bathroom since there is a cement shower basin in there i figure thats where the pots will go, nobody uses that shower its old and not really a place where i want to take a shower
ill have to build temporary walls around it so that at some point they can be taken down if i move or what not, but other wise i think ill have a 3'W X 3'W X 8'T grow space for right now that has a drain in the floor for run off, seems like a win win,
the walls will go up fast since i have construction background and it will be sealed for any light leaks,
as far as that reflective stuff most people have idk if ill have that so the walls may just be white
the light will be rigged to the ceiling with draw wires to adjust height 300W led grow light which should be plenty for that space.
otherwise im not sure what else there is to know thats where you and any others with advise come in.
as far as the grow medium im going to probably use 3/4 Fox Farms soil X 1/4 perlite perlite for drainage as well as 2-3 inches of pea gravel at the bottom of the bucket with a few holes at the bottom. fox farm veg and bloom nutes accordingly
