ericvw: Was wondering where you been, streetie "D" getting chilly up there yet? Sept 17, 2015 18:00:46 GMT -8 *
Daryl: Up and down. 70s/80s and a small drought. I'll take it! Winter will be here soon. Too soon. Sept 18, 2015 0:59:27 GMT -8

bstevenb: I'm stumbling towards a hoop house here in USDA Zone 6. Scrounging and upcycling are been my best friends. I have reclaimed 40 each, 16 inch square X 6i nch chimney cinder blocks. (They have a hole in the middle). OK to use horizontally? Oct 7, 2015 6:40:24 GMT -8
bstevenb: The hoop house will have a 12 ft dome in the center. Wings will be 20 foot hoop houses extending East and West.The hoops will be 14 wide but mounted above a knee wall. A 3 foot knee wall means the hoop tops will be lower than the dome top. Convection? Oct 7, 2015 6:47:24 GMT -8
bstevenb: Maybe a taller knee wall? 5 1/2 feet means more area to heat but the RMH or RS in the dome uses passive convection currents to move heat thru the hoops Really trying to avoid running power out to the greenhouse.. Oct 7, 2015 6:49:51 GMT -8
bstevenb: I'm getting off track.Scale How large a hoop house can be heated with a 55 gallon RH. Solar gain? I'm downwind from 4 of the 5 Great Lakes. Annual Sunny days = 66. P. Sunny = 99 leaving 199 Cloudy days. Clouds rule Cleveland's winter skies. Oct 7, 2015 6:56:27 GMT -8
bstevenb: So my 14 foot metal hoops are set as is my zoning code that forbids a permanent foundation. The E/W dimension of 56 feet is a maximum. I'm too old to want to dig out a pair of 20 foot raised beds to install new hot water lines. Oct 7, 2015 6:59:56 GMT -8
bstevenb: Another scheme has me building a set of two telescoping high tunnels. Winter means the taller one (on top of a knee wall) rolls over the stationery. Advantage ? a second layer of plastic sheeting that creates an insulating envelope. Oct 7, 2015 7:04:24 GMT -8
bstevenb: A rocket stove with hot water storage seems the best combo of storing heat, low cost and avoiding trying to lug tons of material in my raggedy old car and with raggedy old back. Is there a success story in NE Ohio I can visit. Oct 7, 2015 7:08:23 GMT -8
ericvw: maybe you can start a thread or two.... Oct 7, 2015 17:04:53 GMT -8
