He Helps Others Build “Underground” Greenhouses
“Our 78-ft. long and 17-ft. wide design is the most popular,” says Finch. “If you have access to a backhoe and furnish the labor, a full-size unit should come in at around $22,000, fully automated.”
That price includes the cost of fans and 250 ft. of 4-in. diameter plastic tubing required to keep temperatures in the greenhouse above 28 degrees. A 78-ft. greenhouse requires 13 of the 250-ft. tubes buried 8 ft. deep to tap the year-round 52-degree temperature of the earth. The dirt floor of the greenhouse is 5 ft. below the surrounding ground surface.
“Only about 200 ft. of tubing is actually in the ground,” says Finch. “The rest of the closed loop system is used entering and leaving the greenhouse.”
Finch offers the twin-wall, Lexan polycarbonate panels and the framing for the south sides of his greenhouse design. Materials to erect in-ground walls and the “back” side of the structure are available at any home supply store, as is the 4-in. diameter tubing.
“Our materials cost about $122 per linear foot (available in 6-ft. increments),” says Finch. “The construction and fabrication plan package is available for $49.”
Finch also sells his Citrus in the Snow digital report on the geo-air energy system and how it works. The report includes color graphics, notes and comments. It can be downloaded online for $24.
