I've always wanted a secret bookshelf door into a secret room :O
Got plans for a drainage system tied into the flooring somehow?
I've been tossing that idea around lately... it might simplify my world if I didn't have to worry about collecting the runoff.
BoomShakalaka... Yup, that's goin into the 'usernames I wished I thought of' list.
Sheetrock on a grow room floor would seem problematic at the very least. Any spilled water not instantly removed would tend to turn it to mush... maybe especially so with the slightly acidic mixes we tend to use. Not to mention OSB will support much more weight than drywall.
Its mostly a durability solution and it matches the surrounding workshop. The bottom 4 feet of OSB is more durable than drywall and saves me from endless patchwork. [emoji1]I meant the bottom half of the walls, not the floor, sorry. I didn't know if you had a specific reason for that.
Progress has been a little slow lately but I'm getting there. I'll get some pics up asap. I have the door installed that divides the veg & bloom rooms. Also, some ventilation has been roughed in. I have some seeds germinating so I have extra incentive to wrap up the build.
I'm thinking about using an old 4 inch carbon filter on my fresh air intake. I'm not sure if this is a good idea or not. I want to keep dust, pollen, bugs and junk out of the room. Additionally, if my main ventilation fan goes down I won't have stinky air exiting through the intake hole.
