<p>If you heat the water, you can keep the air temp a bit lower. Check this out-</p>

<p>Hi Brent,</p>
<p>There are so many ideas about how to do this that it's hard to know where to begin. If you can wrap your head around the concepts of radiant heat, passive solar heat storage, and enthalpy then you can come up with some really creative solutions. </p>

<p>As for the aquaponic side of things, I think you should take a look at my blog on <a rel="nofollow" href="http://coldweatheraquaponics.wordpress.com" target="_blank">Cold Weather Aquaponics</a> since that's all that it's about. Sorry for the self-promotion. I'd point you elsewhere except I started the blog since I can't find anyone else promoting energy efficiency in aquaponic design.</p> http://www.youtube.com/watch?…tag:aquaponicgardening.ning.com,2014-03-19:4778851:Comment:5541892014-03-19T03:09:53.520ZJason Nhttps://aquaponicgardening.ning.com/profile/JasonN

<p>What if all the lower walls were cob and had rocket stove piping running through them? The thermal mass of the cob and a rocket stove combined could possibly do it. I have been doing some planing of my own on a greenhouse and am doing cob or putting it half underground. I am thinking cob would be better.</p>

<p>We're doing the same thing and are planning to use a rocket mass heater or a masonry heater (very similar) with an earthen bench as the mass to hold the heat that dissipates. YouTube has lots of videos (some good some hokey) and they can be built yourself, if you wish. We'll be running duct work that carries the heat through the floor to heat the GH. These heaters use a LOT less wood, their combustion is nearly 80-90% so your only putting out water vapor, and the mass can easily hold heat 2…</p>

These heaters use a LOT less wood, their combustion is nearly 80-90% so your only putting out water vapor, and the mass can easily hold heat 2 days. They burn at incredibly high temperatures if constructed properly. House will also have one that will include oven space and water heating capacity. Hubby just ordered a book with plans from the Masonry Heater Association. The concept has been in Europe and Asia for generations. </p> I am also in a northern clima…tag:aquaponicgardening.ning.com,2014-01-03:4778851:Comment:5391822014-01-03T05:04:54.910ZLayne allenhttps://aquaponicgardening.ning.com/profile/Layneallen
I am also in a northern climate and have been researching methane production thru anaerobic composting for a fuel source. My hope would be to generate enough methane to heat a greenhouse through the winter. I am still working my way through the theory but I thought I'd throw it into the discussion. Please let me know if it is one of those looks great but don't work ideas.

<p>I said it's better... not a cure-all for temperature problems. If you have warm air and a cold root zone, your plants are more likely to die.</p>

<p>And yep, tomatoes are summer lovin' plants, so cold temps will definitely kill them off.</p>
