Charts up to today:

   You can see the lows steadily climbing in the GH:

Thanks for sharing...

I have a few comments further explaining my design reasons:

1) I'm well aware of water's greater thermal mass capacity (specific heat of 1 vs about .25 - .5 for rock  / concrete)  I chose not to use water because unlike air... water makes a mess when it leaks.. :)
given this was an experimental install, I was concerned any settling or other issues might cause a leak I couldn't get to to fix.

2) I wanted a greenhouse completely independent of power (EMP proof). That meant no fans or pumps.  Not a problem , as convection is quite efficient. I chose again to steer away from water (as much of a fan as I am of water in so many ways!)  also, water piping and connectors are much more expensive, especially when you rely entirely on convection for circulation as friction losses can rapidly degrade performance on smaller pipe diameters.  Air ducting was cheap and easy to do, and I figured since I was planning on heating all the soil underneath.... I'd have plenty of mass.  So far I've thawed the footprint of the greenhouse plus some buffer (more near the furnace, less further away as you'd expect)

3)  that round tank in the video holds 50 gallons of water,  I added it as an afterthought about a week ago... temps are steadily climbing on it... especially on sunny (few and far between these days) days of course.  I had considered adding an undersized coil from the catalyzer over to it to speed heat transfer (currently just running the 6" air output over it) but not sure I'll need it.

I am looking at passive venting systems next...  according to the stats I've uncovered in my research, I'll need 54 square foot of vent space for inlet and again for outlet. (GH sq ft is 288)

Anyway... those are my thoughts...

I'd love to hear your opinions / expanded thoughts on mine.  :)

cheers for sharing!

EDIT:
oh yeah... built with no budget from scrap everything..
except the little bit of ducting and the plastic, a friend sponsored me on those, so cost was DEF a factor also...

for passive heat use this reference

also known as passive solar home

psa is known as passive solar assistance

psh is passive solar heating

Hey Reebotag,

Can't watch the vids. Do you have another link?

or an update?

Im very interested!!!!
