The translucent CrystalCave™ Tunnel Greenhouse will protect your plants against birds, harsh weather and frosts and is useful to warm soil early in the growing season. CrystalCaves are lightweight and freestanding so they can be easily moved depending on your needs. There is adequate space for full-sized plants and tools or several layers of seed flats and shelves along the length of each side. We offer two sizes (9-foot and 11-foot) and they can be placed end-to-end to produce a longer shelter or special ordered in additional lengths.
Easy Set Up
Your CrystalCave arrives with all hubs and clips attached. Just slip the interchangeable poles into the hubs and in 40 minutes your CrystalCave is complete. Once up, you may lift or turn your CrystalCave into position. The CrystalCave can be disassembled in 5 minutes, just remove the poles and roll up the covering into a compact package that is easily stored or transported.
The Covering is made wholly of a superstrong, tear-proof multilaminate woven ripstop film which will not rot or mildew. It is UV stabilized to withstand up to 3 years full sun exposure and treated with fire retardant. The fabric is a super strong, high tensile strength, rip-stop, completely waterproof, mildew resistant, and cannot be torn by hand even after it is cut. This US made, proprietary material is the finest material we could find to make our tents from.
The Poles are of high quality US made PVC that is admirable for its strength, resiliency, long life, natural UV stability for a long sun life, and its strength to weight and cost ratio. The poles we use are Class 200 PVC tubing.
Shelter Systems’ Patented Grip Clips that we use to join the domes cover to its poles are molded of a UV stabilized resin blended specifically for it high strength and durability.

The CrystalCave comes complete with clips and connectors attached to covering, poles, stakes, and instruction manual.
