Mike jay,
thank you very much for the welcome, i plan on orienting it east-west yes the land is very flat. Ive considered insulating the north side but im worried even though its on the north that ill love alot of useful sunlight. It is dug into the ground to add high and act as good insulation.Thank you though for the advice and i welcome any more you may have

hi im looking to build a 15x 60-foot aquaponics greenhouse in southern Minnesota. The plan is to sink in about 4 feet in the ground with a 5-foot double plastic wrapped greenhouse tunnel above. there will be large water pools (1500 gallons) and many many concrete blocks for constructing grow beds that will make wonderful heatsinks. id like to heat this year round with a rocket mass heater but I've never seen one heat something this big in a place that it gets so cold in something that's not very well insulated. Is this possible? how big do you think it would need to be? how much wood do you think id go through? sorry if this is alot to ask of you guys but i really wanna learn what I can before i commit. Thanks!
