@qclabrat Yes, it is posted across 4 pages in @Gemma's thread: Do you have a greenhouse? at https://www.gardenpondforum.com/threads/do-you-have-a-greenhouse.22332/

The most important consideration for a winter greenhouse if you live in a cold climate...and I see you are Zone 6a...is to insulate the ground in the greenhouse. Insulating the walls, etc. is relatively easy, but if you don't insulate the floor, you'll lose a ton of heat through the floor. There are many ways to insulate the floor...even use it as a heat sink. I am partial to the two methods here...especially the "Swedish Skirt" method if you can't dig a regular foundation because of the ground placement or to save $$ https://www.ceresgs.com/solar-greenhouse-basics-insulating-your-foundation/

We have built greenhouses in the past from cattle panels using metal fence posts on the sides to hold the cattle panels in the proper curve. Presently, in a cold climate, we dug into the ground 42" to take advantage of the relatively warm year round temperature of the earth. I do supplement the light with cheap LED grow bulbs.
