Hello from Central Oklahoma. I'm interested in building a greenhouse and the more I research, the more overwhelmed I get! I would love to know what greenhouse designs have been successful for you in the Texas/Oklahoma region.
I was considering doing a Greenhouse in the Snow--partially submerged geothermal greenhouse, but I'm concerned about our high water table here and wonder if it would be a covered drainage pond for most of the season. Does anybody have one of these in this area? It seems like most of these types of greenhouses on the web have been built in the Northwest area of the US and I'm wondering if it would actually be too hot to grow anything but tropical plants here in OK.
I'm also considering an above ground geothermal greenhouse, and would appreciate any words of wisdom on geothermal!
Lastly, if you have a non-heated greenhouse (or one that uses emergency heating system), I would love to know what you are able to grow! Thanks!
