I take down one flower room at a time, and thoroughly clean in between runs. I use prokure gas and liquid prokure as well as spray the whole room with zerotol.
My veg room does have plants in it at all times so it’s harder to clean but I do veg for a few weeks in my flower room after going to bigger pots, and every couple months I’ll move my mothers and new clones to that room and do the same thing in veg.
My veg room still exchanges air so if I do have any issues it’s usually in that room and in the summer. I plan on adding ac and sealing that room as well before next summer.
And yes we do it all, well we have paid for help trimming a couple times but they never work out and she has to touch up the product to get it how we like it.
I only had one other friend help with the whole building, no hvac, no electricians. Well besides the spray foam guy it was just me and one laborer. The building started off as metal pole barn with no insulation, basic electric and no water or drain. I wired up new 200 amp service, framed out rooms, painted, water line, drainage, installed 3 mini splits and set up the rooms.
I have another garage and just replaced the roof in plans to start another build, but they are talking about doing away with caregivers at some point so I’m debating whether or not I want to invest so much in that or just try to get a commercial building in town for a micro business. It’s not like I’ll stop if they change the laws it’s still only a misdemeanor for up to 200 plants, but I’m kinda just waiting to see how it plays out before going bigger here. The growing part of the micro I have no problems with it’s the paperwork and storefront that has me hesitant, but a small grow without a storefront will really take a hit when wholesale prices go down.
