In addition to his previous notes since 1992, it now includes 10X the commentary, explanations, instructions, and details. 20X more color photos and detailed diagrams, complete with many more graphics and illustrations than in the original publication.
“A must-read before you buy or build any Geothermal greenhouse.”
This new version also includes three (3) geo-air systems which he is using at various facilities. Although all are geothermal and geo-air technology, all three are quite different in function with notes and detailed pro/con comments on each system.
This is larger than any report in previous years and contains more details on the recent manufacturing and technical performance of the Finch ‘sun pit’ style geothermal greenhouse.
The new Citrus In The Snow is now more than 170 pages of an easy-to-read PDF format, updated by the GreenCube Research Institute staff.

The Technology- This valuable report is the most accurate, "real life" and successful usage of Low Grade Geothermal use, and will certainly become a very popular and profitiable Green energy source for 2023 and in decades to come.
This is possibly the most realistic, economical, sustainable and the simplest technology to heat and cool homes or greenhouses.
This technology is the cheapest, efficient energy source now getting all the International attention?
Russ Finch didn't invent the Geothermal Greenhouse concept, but he read about the 'Grow In The Snow technology'  50 years ago and was inspired. But unlike most people who read about this ‘Grow In The Snow’ technology in 1972, Russ actually stepped up, and did it. A lot of trial and error, but he did it! First his home, then atrium, then full greenhouse.
Whether you are a building contractor or a DIY consumer this well documented and detailed Report is a must.
After you read his detailed Report of his actul use of 3 types of geo-air systems, you will wonder why it's not being used in every home and business in the US and globally.
This graphic and illustrated workbook you will have all the basic information you need to design and build your own geo-air greenhouse system, or even develop your own geo-energy construction business.
In addition to the easy, and profitable construction types, see how anyone could easily build a "free energy" greenhouse anywhere and earn more than $100,000 per acre annually.
