think this is a great idea even for here in MN.

support in a tea. Ferment little cups with molasses and it gets even better.

Just fyi for anyone that is interested.

insulation, for a start. 15 degrees at night is just a little too cold for most, you know, water based plants.

Nights are so long there in the winter months, he would get very few hours of sunlight. I'm guessing really efficient grow lights, probably LEDs in the red and blue part of the spectrum (the only parts plants use) and reflective mylar on the inside of the dome, both to retain heat and give the plants every chance to eat every photon of light they can manage to catch.

I wonder what happens when it gets 3 meters of snow. And what's his power source for the lights and heater? Does he run a little generator outside the dome? Maybe a generator inside where it's warm, with the exhaust ducted to the outside? How much diesel fuel does it take to grow a tomato? For the prototype, he may wire his experimental dome into the university's power grid. But for people in remote Yukon areas, off the grid, they'd have to make their own power. Windmills, anyone?

Hydroponic growers have been doing this for over 30 years. The only crop that has the value density to make such an operation viable is marijuana and the legal expenses of that crop make it problematic.

Was gonna try to get on Shark Tank, but it seems that is hard to patent, and they are so fussy about that.

At least a basic description anyway, dont want you to give away any secrets you developed.

thing is, it's not patentable and won't make news on tv.

If the government won't protect their investments, they're just not interested.
