Hello everyone here, I am new to the forum and hope I cant get some really good advice on my next grow room build. I just moved (renting) and have a un-attached garage in back hooked up with a separate electric panel equipped with 100 amps. The exterior walls are siding t-one11 and inside has been sheet rocked, the ceiling is open with truss joist and it has an aluminum roll up door and a regular side entry key lock door, also it has a window on one side. I started a couple years ago first with a 4 x 8 tent and 2k then went to a room with 4k air cooled with intake and exhaust.I had to move so i am now ready to start up again I am in the Sacramento valley area where the summers are brutally hot and the winters can get pretty cold.i have basically all my old equipment 6' and 8' air cooled hoods, fans portable a/c 70 pint dehumid ect... my new property management frowns on growing per the lease it was extensive so my " Dilemma" is that my next room HAS TO BE STEALTH. I am leaning towards a fully sealed room and need advice on the build reflectors I have already bought the co2 tanks so at this point I am thinking of building 2 inside walls inside the garage like an " L" shape and run three 4 x 8 trays in it. I am also willing to go to open reflectors and upgrade to a mini split a/c, so those are the basics sorry it's such a long read but I would really appreciate any really experienced grower/builders/consultants to help me from here. I used to be a carpenter before i became disabled so the building will not be an issue, I just need it to be odor free from neighbors and control the climate as best as possible. Again any help, ideas, reccommendations on the build or the equipment will be helpful. thank you all in advance. hope to speak soon with you all. peace .
