Also going to vent my indoor heat to the GH Double wall if I can to extend season from April 1st till November 15th..I was seeing if it was even possible to finish some strains I had with materials I had. Gg4 and wedding cake finished. Going to try and build a properly done greenhouse this summer. There are autos that won't finish here if we have a late spring and a early winter. Last summer we had from June 1st till October 10th. That almost never happens.
I'm on the hunt for the earliest of the photos that act like photos.
