Bloomcabin High Tunnel Greenhouse 10x13 review

The Bloomcabin High Tunnel gives you 129 sq ft under 6 mm polycarbonate on zinc-coated steel arches, a published snow load of about 32.8 lb/ft² and a 12-year warranty, the longest on our list alongside the Scandiglas. It extends in modules up to 388 sq ft. The catch: Bloomcabin publishes no wind rating, and the $3,372.97 price is after a 45% discount Bloomcabin shows against $6,132.67.

This is the most farm-like kit on our list. At 9 ft 11 in by 13 ft 2 in, you get 129 sq ft: enough for two long beds and a central path, with room for tall crops in the middle. The frame is zinc-coated steel "Omega" profiles, 56 mm wide and 1 mm thick, with an arch every 3 ft 3 in and extra arch reinforcements. Each arch goes about 13.8 in (35 cm) into the ground, which is how the tunnel holds itself down.

The peak is 83 in, 6 ft 11 in. Comfortable down the middle, lower over the beds, like every round tunnel.

Bloomcabin uses 6 mm (0.24 in) polycarbonate with UV protection and puts a 10-year warranty on the panels. The snow load is 160 kg/m², about 32.8 lb/ft², one of the strongest figures on our list. What we could not find is a wind rating. That is not a sign the tunnel is weak, only that Bloomcabin does not publish one, and our formula scores unpublished criteria low on purpose. If you live in an exposed, windy spot, ask Bloomcabin before ordering.

Two side windows give you cross-ventilation, and Bloomcabin sells an automatic roof vent separately. For a summer tunnel full of tomatoes, we would want both. The real party trick is the modular length: the tunnel extends in 6 ft 6¾ in modules up to 388 sq ft, so a first season at 129 sq ft can grow into a proper kitchen-garden tunnel.
