It's the Rimol Matterhorn. We piped water in from the house (only cold, huge mistake - but we're putting a mixer in the basement). They put electric in the same trench as the water. We put in the gas from the street - another mistake because the power company considers it a business, and upcharges, even though I don't sell. But it's on a separate lot, and since it's not a residence, the only other category is a business. The heat is an overhead Reznoir hot air. We are looking at putting some type of heat under the benches, with a hot water system. Much more efficient, but difficult to manage with large pots (up to 32") and moving benches. I should have gotten a heat curtain, but it was expensive (6,000) and it would interfere with the fan system (3 huge industrial fans at the peak). To do over, I would put a masonry wall at the bottom because part of it is below grade, I would do a nice looking solid wall at the north end (we put in insulation this year over the polycarbonate), and I would try to find some way to keep the heating bills down. I love the concrete floor, even though others advised doing rock - I can clean it and I don't slip in mud. And I would make it at least a 20 x 48 (I bought the major pieces of steel in case we ever expand). I would like it wider, but the lot is only 36 feet wide.
Sinbad always fell victim to the fungus among us. Maybe my new spraying routine will help.
