@Sasquatch Howdy I think we had one or two frosts and one frost warning. 35-40’ average. This thing weighs about 10 lbs. I can pick it up with one hand to move it. The plastic kinda goes out to the side so that’s why the bricks are there to hold the plastic down and the gh. So far it has withstood pretty stiff winds both from the west and the east, rain, cold weather and just spits in their faces. When I open it in the morning I get warm moist air coming out and the girls just respond to it really well. I take them outside for the day if warm. You can see it has it’s own weather system lol and thunderstorms when the heat meets the cool jk. I would not have had such a successful grow going on now without it. I love it. The only con is the shelves do not hold 75 lbs as stated and are very flimsy (I let Amazon.com know). I am in a wheelchair so I have to have things up, hence the cinder blocks. I can fit 10 cinder blocks inside. You can’t go wrong at the price. Come and follow my journal and you can see more pics. Good growing and happy Harvest to you. ‘Come grow with me by HCG’ and start one for your self. We SoCali’s have it so good!
