If 66 full sized plants would fit into a smaller greenhouse that would be great, but they won`t. I can only get 60 of them in under the tunnels as it is. I`m thinking there 10+ x 40+ tunnels next year with lumber supports ,ends, vents, Fans, and wood fired forced air heaters. I`d think two swamp coolers turned 12v and screened on the outside to be pollen proof to 2 microns at the low end and two self closing flanged greenhouse exhaust vents with pollen screen on the high side end. At night I could run circulation while using sulfer burners to help prevent mold spores. Toward the beginning of flower in the Fall when it just starts to cool down I could run CO2. I was thinking if I wanted to used each greenhouse from start to dried bud , I could. I experimented last year with the tunnels and while the air is just right they nearly had the hanging stocks dried. If I put ends on the tunnels I could control the moist air much better. I`d still need to run fans a lot. Add a few T-5 lights and I could extend veg and if I wanted to add a blackout roll over cover I could start flowering earlier. Much more control like an indoor grow. The difference would be most of the light cycle would be provided free by the sun. Much of the heat for cooler nights could also be collected with circulated water system installed to collect heat from the sun in the day and stored like in a thermal collector until the cool of the night then recirculated back into heat expiration units in a closed system and timed 12 water pumps doing all the work by battery and solar collected energy. The point would be to use as much of the natural surroundings and available energy as possible. I`d need two more controllers so I`d have one for each greenhouse.
Once I get this kind of set up I want to put the permanent greenhouses in mostly under ground. This would help keep the temperatures even regardless of the time of year. I wouldn`t need ac or heaters besides maybe a passive solar heat collector. All fans could be 12v and all water pumps as well. Thinking I could run a Simi hydroponic /soil system with air and temp controlled reservoirs. The top would be triple pane glass sheeting on steel frame. I could grow my vegies and meds year round! With a larger set up I might even get very long season fruit ,nut and berries nearly year round. Think fresh pineapple and avocados ! Oh Lord just get me on my property and I`ll experiment and in time flourish !
