100+ F
I have no way of telling how much water my swamp cooler actually uses. When
it runs it pumps the water back over the aspen wood pads. It pumps a small amount of water out into the drain so there isn't a mineral buildup. When I started the Greenhouse 5 years ago I did not see a big increase in the waterbill. I don't think the water usage is much. Gene "Manelli Family" wrote in message ...

As a point of reference....in the DC area yesterday it was about as humid as it can get and the air temp was 100F. The min/max thermometer in my greenhouse was 86.7 degrees as a high. That is about the hottest the GH has been all summer and we have had a couple of days in the high 90s. I have 50% shade cloth on it right now and use tap water in the Swamp Cooler. Tap water is very warm this time of year so the cool is mostly coming from the air movement and the evaporation. Can you tell me approximately how many gallons of water a day your SC uses? Good growing, Gene "Manelli Family" wrote in message ... "K Barrett" wrote in message news I used a lot of the advice from Charley's greenhouse when I built my GH. I've provided a link to their tips page. I used their formulas to calculate how large a swamp cooler (evaporative cooler) I'd need as well as how large a heater. My GH was 8x16 and I put Charley's swamp cooler in it which was over kill, but when I expanded the GH to 8 x 30 I didn't have to get a larger cooler. It still works fine. http://www.charleysgreenhouse.com/index.cfm?page=_tips OK. I checked them out. The air here is not dry but quite humid from spring to fall. It's only dry in the winter but the plants still thrived even with the 20 to 30% humidity. Wetting the gravel in winter with the hose would bring it up to maybe 40 or 45% for a few hours - when the hose wasn't frozen. Then I'd use a 1g spray bottle. These swamp coolers wouldn't help much as they only drop the temps down 5 to 10F for the affordable one. That's not much when you're dealing with 120/130+ all summer long. Also, I don't know how many sq. feet the Rion is because of the roof shape. The larger SC is $590 and needs a constant water supply. Blasting the limestone to run a line is cost prohibitive as is this cooler. We've already spent a lot more than we figured on on the Rion GH, what with all the gravel, cement, rebar, bubblewrap, shade-cloth, fans, heaters, extra weather stripping etc. etc... etc... ad infinitum................ |
