 Outdoor greenhouse w/ desert climate? 
#15904220 - 03/05/12 05:26 PM (1 year, 2 months ago) |

Ok so Ive got some experience with indoor cubes and I want to expand my knowledge of mycology and try doing edibles. Ive just started researching on the subject and I haven't seen much info on edibles in hot climates. I live in a desert, ridiculously hot in summer and little to no humidity (10-20%). I going to get materials for a simple outdoor greenhouse, and i just wanted to know if anyone has had experience in growing in hot climates. The main benefits of the greenhouse is the humidity, but the draw back is when the temps rise to the high 90's whats gonna happen?
I want to include a mister set up, just hooked up to the sprinkler timers and stuff. Not exactly sure how to rig the water lines up but my dad does so Ill have him show me. and I need to add a fan or too, especially for the edibles not being very CO2 tolerant. What are some good strains for this climate? And what ways can I make the greenhouse conditions more welcoming for my mushrooms? Its basically an experiment so anybody's thoughts will be put into the project. Ill take alot of pics once I get my ideas straightened out.
Peace

Check this out Greenhouse cooling. Rig an evaporative cooler. Super effective in dry climates and humidity to boot.

Yes. Your climate will work with a "swamp cooler" very well, and these
are a very low cost (relatively) way to cool in the desert.
Cool link.
Good luck,

Thats a sweet set up. The pump is outside too and it keeps the water cool?

I imagine that you will want to keep the water reservoir shaded.
(I do not think that the pump does anything but circulate water)
Good luck,

doesnt seem its good for a fruiting chamber
Quote:
4) - Evaporative cooling: This works best in arid climates. But doesn't do much when humidity is close to 100%.
PS i accually used to visit a greenhouse like this pretty often and yes it cools pretty well in the middle of the summer when temps here are around 40C though u shud consider the 100% humidity thing again..

Hmmmm....the OP said "I live in a desert, ridiculously hot in summer and little to no humidity (10-20%)."
I see no humidity problems for a swamp cooler here...

unless ur planning to cool ur fruiting chamber wheres the humidity is around 100%

if you plan to cool your incubation room to 29C it should work because theres no humidity there... but if you need to cool your fruiting chamber for around 24C itll be problematic since you need the humidity to be around 100% and it says this type of cooler have problems in places with high lvls of humidity

Ah, I see.
Let me point out that it is only external (i.e. very dry) air that
will be passed through the proposed swamp cooler.
I was never recommending that a swamp cooler be used to moisten and/or
cool air that was *recirculated*.
That would require some other technology.
So, there, we are on the same page after all. ;0)

This guy grows in the desert of mexico by arizona. His set up seems to be what your looking for.

It's an obvious point, but keep your greenhouse out of direct sunlight. My first outdoor greenhouse got direct morning sunlight and the temp jumped up to over 100 when the air temperature was only in the high 60's.

the video is great, that setup it perfect. But I'm not sure what end the fan and swamp cooler are supposed to be on. He says he has two fans at one end and the wet wall on the other. He continues, that the fans "pull" the air thru the swamp cooler pad. How would that look?
A negative pressure system? Negative pressure systems have exhaust fans that blow air out of the building, creating a slight negative pressure (vacuum) to draw air into the building through designed inlet, in this case a swamp cooler pad.

Im still researching and I just went to home depot to check out prices, and holy shit its expensive. I mean sure the fruits should turn a profit eventually, but thats a good 2 months before seeing a return. My scale is pretty small, maybe 8' x 12'. I plan on getting a small fan and a swamp cooler set up. But for all the money is this worth it? I could fit a good number of oyster baskets and or logs, anywhere from 3 - 9, but I'm more worried about the conditions the greenhouse will provide. Its basically a balloon with a fan at one end and a wet towel at the other. Sun or no sun? What about the heat, if its too hot then what? Science doesn't lie but the factors involved are all dependent on each other. WILL this work? any experience?
Thanks for the help.

Honestly, two months before profit is like rocket-speed in business terms.
I will leave you to your ruminations.
Good luck,

Yeah that is true but when you invest all your money two months is a long time. I'm going to make up a grip of jars and keep researching, although at the moment this looks possible

can the greenhouse be on the side of my house? it won't get much sunlight other than the early morning until the sun passes over the house, but the sun is really bright and the houses around me are white and its always bright , its just not directly in the sun.

My greenhouse only got morning sun for about two hours and then was shaded the rest of the day, but the temperature still shot WAY too high. I live in the pacific northwest, so I'm guessing the sun we get isn't as intense as what you experience. The only way to know for sure is to set up your greenhouse and see what happens, but my gut says that any amount to direct sunlight will be too much.
