I have over a year growing now and just finishing up a 4th grow in my basement, which is huge, and moving into a 2nd story room that's much smaller. easier to manage heat, humidity, etc. I will be stripping wallpaper prepping with trisodium phosphate and painting white. will the TSP along with paint be well enough to sterilize? or should I clean with bleach and water after paint just the same. thanks in advance.
