|Good Morning ISO,|
While home shopping in 1981 (after Chevrolet moved me to Houston), I looked at homes in Tomball TX. Humble Oil Company had large gas wells in Tomball.
Part of the perks to drill in Tomball was free natural gas for rural locations.
I remember marveling at the outdoor pools being heated during the winter months. The steamy water would lift out of the pools all day.
Those homes were well above my pay range, but your story has brought back the memory.
P.S. I think you need to have a heated pool out in front of your greenhouse.
How relaxing to watch your seedlings sprout, as you sprint into the warm water. LOL
