Survived a windy spring
"Anchored it well and it laughed off 40 mph gusts. Peak roof sheds rain properly — no pooling on the cover."

Roll-up windows are a game changer
"Ventilation control on hot days is so much easier than my old walk-in. Tomatoes are thriving."

Weekend build with one helper
"Frame parts are labeled and clear. Two of us had it up and covered in a Saturday. Instructions were actually useful."

Great for the money
"Cover material is thicker than expected. Wish the door zippers were a bit heavier duty, otherwise a fantastic buy."

Extended my growing season
"Started seedlings 6 weeks earlier this year. Interior stays 15° warmer than outside on sunny days."

Perfect for our small farm
"10x20 is the sweet spot — big enough for market crops, small enough to heat. Freight came fast."
