unfortunately it's looking like my attic is the last resort and I'm going to take advantage of it. I might add that I live in really cold winters and really hot summers so I know I have a challenge ahead of me. the biggest concern I have right now is what is the best material to make my grow room out of in my apex? I plan on insulating behind the two by fours but I was told not to use plywood. any suggestions? Thanks much. Peace Sent from my SCH-I535 using Grasscity Forum mobile app
Who told you not to use plywood and why? Most of us live in houses made with plywood. As far as grow rooms my rooms are just space blankets like a curtain with air space on the bottom and top. My rooms are warm but not hot, its just like Hawaii in my rooms 80F 45%RH. I run 1,000 watt lights and don't run any fans at all. Many noob growers think you have to grow in a light proof sealed up tent them wonder how to cool that oven. Attics are ovens though, you will have to pump hot air out and pump cool air in.
In a forum on another site. Had to do with moisture and the board swelling from humidity but I do plan on putting a humidifier and dehumidfier combo to control the humidity. Thought I was missing something newbie and all. Thanks brother
Never vapor barrier or plywood the studs on your roof. You seal your roof THAT IS A NO NO!. it will create hot spots on your roof and wreck your shingles, plywood and you will have to rebuild the whole things as roofers wont walk on it to re shingle. I would build a room free standing in the middle of the attic slightly shorter then the roof. Vent it to a direct port out of your house. split the room in two or make it longer if u need veg/flower.
The reason you don't use plywood is because it has an R value of about zero. You will build up moisture, icicles will be hanging from your soffits and will cause a bit of a problem. In between your studs and anywhere wood comes together is a highway for air leakage. In order to have a successful, problem free grow, I'd Insulate and air seal your attic. If you are unfamiliar with weatherization, remember that it is key to keep conditioner spaces conditioned and anything that is conditioned going into unconditioned space ie warm growbox in cold attic, everything needs to be insulated with xps board, fiberglass, etc. Sent from my XT1080 using Grasscity Forum mobile app
Never a good place to grow anything is the attic, major temps swings will make you cry more than once, use your closet!
You do not want to insulate your attic ceiling unless you use some special means to allow for ventilation, installed by an expert. Insulating by regular means can cause moisture problems for your roof since the air will be trapped below the roof and the insulation. Also, if your roof becomes to warm it can cause the snow on the roof to melt during cold periods and refreeze under shingles or in gutters. im telling your right now you insulate your attic roof you will be replacing your entire roof shingles and plywood within two years due to water damage. I am an industrial insulator by trade work for the international heat and frost insulators union, now Residential is not my ticketed field but the way heat and moisture and insulation dosnt change between a steam pipe and an attic. if the moisture is trapped in your attic it will soak into the wood. also creating heat spot on your roof causing snow to melt and refreeze under the shingles and ply wood. When people say insulate your attic they mean use loos fill in the rafters to keep the heat from traveling into the attic period. Only time u can fully insulate is as stated above you have an expert install a proper ventilation system to handle the new amount of heat going into your attic.
