"This is my GH heater. It is a "Rocket Mass Heater" and the mass is the 2500g of water in the AP system. Water stores more than twice the BTUs in terms of weight or volume of rock or cobb. The black pipe inside i3 @ 7 feet of 3/4" SS…"
I saw a request the other day about how to deal with high humidity in a GH and was curious about that myself since it rains in my GH during the winter. Just now it occurred to me that, while it would tend to decrease temps in the GH, if you took a small pump and circulated water (or anti-freeze) outside to cool it and back inside to create controlled condensation you could in essence have a cheap dehumidifier. If you catch the run off from the condensation lines you just put it back into your FT. Whadaya think?
Hi In your EMAIL I believe you mentioned that you hadn't come across insulated I B C systems ? The first thing I did was to insulate the system ,cool in summer warm in winter .The grow light eight T 5 lights combined with sump tank give 12C- outside Tem 9C fish tank 19C -,going to install gas heating for G H ,simply the grow lights go out at night , the gas heater can maintain tem to about 15C .When it gets colder will send you readings .My first winter aquaponics .I like the idea of using freezers good insulators
Jeremiah, what do you think of this greenhouse design? I came across it while dreaming of creating something like it on my parent's land in Door County. I'm not thinking of the "rooftop" aspect, but more just the "bucky ball" shape, which would be easy to build, shed snow and wind load, and generally be awesome. Then perhaps one of your covered fish tanks right in the middle? Wonder if I would need to excavate ala a root cellar to be able to heat it thru a Door Co. winter? Could it be done with plastic covering? I just started surfing your site so please excuse the newbie questions.
