A very beautiful plant to behold. Have you ever considered using a large clear tote of water as a source of free heat at night? Given the abundant sunshine you have there you should be able to get a decent amount of heat stored in the day to radiate at night. I have solar hot water heating for domestic hot water use and it’s amazing how much free boiling hot water you can get on a sunny day and store in a hot water tank. Adding some plumbing pipes with a circulation pump (sort of like you did to thaw your soil with free hot air) you might be able to achieve similar results and be closer to a net zero energy usage for your grow. Just a thought as you seem pretty handy and into using what Mother Nature provides to you for free.

Hi Mike ,those are some good points, I wish actual daylight hrs equaled total sunlight hours ,that be nice but we are pretty cloudy for long periods of time, I do use the sun when its out ,I built solar water heater collector years ago to heat my 275 gallon IBC tank for irrigation , taking my 40 degree well water up to 80 degrees when the sun is out, as far as heating the gh, a single layer of 6 mil poly doesn't really have any insulation value, so for me natural gas unit heaters are the best bet, the trick is don't look at the bill ..lol
