One wet wall and one exhaust fan, without the roof vents, you can cool down this greenhouse. That's amazing. I'm going to build a 12'x24' GH, your video really helps, thank so much.

[@greenhousesolutions1074]

For that cubic feet use a 24" vent fan and 60"x34" opening with your cooling pads.

I'm in San Tan Valley, AZ and I put patches of shade cloth up inside my greenhouse just under the plastic. This is my first year of gardening in a greenhouse. From what I can see, that there is a sweet set-up for you but as soon as the dew point rises out here it wouldn't do me any good.

[@greenhousesolutions1074]

Still helps a lot. Just works better at lower humidity. We grow all summer even with high (85%+) humidity.

[@greenhousesolutions1074]

Shade cloth works way better outside the poly. Keeps the poly cooler as well.

[@justgivemethetruth]

Why the shade cloth on the inside? Also, I thought AZ was very low humidity ... how would the dew point get high?

[@melparrishjr]

@@justgivemethetruth Most of the year AZ is very dry but durring Monsoon season it gets extremely humid. It lasts from the latter part of June through September. It's not constant but irratic and sometimes without warning. Just this year we had a gazeebo out there without the covering on it and Monsoons kicked up over night an threw it over the fence and wrecked it before we even got to use it for the first time this year. That was just the naked frame all by itself. Without a permanent structure to do it in Gardening in Az is nearly impossible. I was a novice gardener with a green house when I should've been using a shade house! Temperatures exceeded 120 degrees F in the green house and the only things I was able to grow were Hydroponic lettuce and tomatoes. Everything else just died due to all the rapid changes in the environment. AZ weather isn't always gentle or consistent. Even my dragon fruit got water logged and died in the monsoons. They don't like water at all and the monsoons just dumped it on them!

[@MichaelMarko]

This is great!

[@alexkuhlmann]

I found an excellent formula to determine the size of cooling pad that you will need depending on your greenhouse footprint. "The amount of pad area needed is calculated by multiplying the floor area by 8 feet and dividing by 250 for a 4-inch pad or 400 for a 6-inch pad. For example, a 30- x 100-foot greenhouse with a 4-inch pad would require 96 sq.ft. of pads (30 x 100 x 8÷ 250 = 96 sq.ft.)

[@greenhousesolutions1074]

Humidity has a lot to do with the cooling as well as the cfm of the exhaust fan. The lower the humidity, the better and more efficient the cooling. We have cooled a larger area just by adding an extra exhaust fan. Thanks for the info.

[@alexkuhlmann]

Great info - thanks for posting the detailed video. The rain gutter perimeter is a great idea.

[@zekiah2]

@@greenhousesolutions1074 I am thinking about building one of these for my existing Green House but the problem is my greenhouse is about 27,000 sq feet. Do you think the system could be upscaled to work with a greenhouse this big?

[@charlescochran9803]

Would you be so kind to give me your material list? You have a great build. Thanks

[@BSC419.]

Does it have to be in an opening or could you build a freestanding frame and have it inside the greenhouse

[@Mzvemz]

How do you figure out how big of a water wall you need for the greenhouse ?

[@carlthornton3076]

Great!!!!

[@badenton2]

This is great stuff. For those of us in the desert southwest, what do you do with your wall in the winter, when you don't want cool night air (as low as 25-30 degrees on the coldest nights) coming through your permeable cardboard wall? Do you cover it manually or have some kind of automated shutter?

[@greenhousesolutions1074]

I cover it manually. I use painted plywood or OSB on the outside and as an extra, poly/plastic on the inside.. Thanks for watching.

[@user-kl1nd1mx9x]

It is recommended to know about thermal insulation cotton curtain (manual) and windproof rolling curtain (manual and automatic) for thermal insulation in winter

[@rroyiitzhak]

do you know what is the water consumption for this scale of greenhouse?

[@flatout5815]

This might save me a fortune. Only thing different from a swamp cooler ordeal is they have a fan pushing air in. One thing that might make it operate even better imo might be to bury the water resivoir deep in the ground to make the water even cooler through the hot days.

[@rplatow4120]

Yes, absolutely. The cooler water is a plus!

[@richardtolley495]

hot water evaporates faster. cold water has not been proven to cool a greenhouse faster than warm water. I have a swamp cooler and I'm changing to this wall because it is way better.

[@justgivemethetruth]

@@richardtolley495 That's an interesting point, but even without any additional cooling as the water goes through the cardboard material it will be very cold, so there's not really any point to digging a hole and cooling it because it will cool off very quickly. Maybe it needs a way to heat it rather than cool it?

[@meganmondelli4426]

GREAT video. Going to follow it step by step for my greenhouse wet wall. THANK YOU!! Q: what does the 1/2" pipe connect to other than the float valve? is this step (using a float valve) necessary?

Using a float valve is not necessary, just so you don't have to fill by hand. Thanks, Randy

very very goodenjoy man

[@sergeantseven4240]

Would it be better to point the holes upwards so that the water flows out and over the top of the pipe?

[@greenhousesolutions1074]

Tried that. Works best down. Water flow and and even pad wetting better pointed down. Thanks

[@TheGreatTimSheridan]

you might want a small drip reservoir so the pump just fills it intermittently, then it dribbles for an hour over the swamper.. the reservoir needs a float valve to switch on the pump when the water has dripped down.

[@greenhousesolutions1074]

Full video shows the float etc. I use a timer on the pump for the cooling pads. Depends on time of year/temperature.

Wish I could just buy the kit!

[@marthaparungao9162]

I wanted to know how wide your gutter is and how tall your evaporative cooling pads are? Are you leaving 2 inches on each side and the top for expansion?

[@greenhousesolutions1074]

4 inch gutter, 5 feet across and 33" tall to allow for a 36" tall screen to keep bugs out. (36" screen is standard and not expensive). Almost no expansion with these commercial pads.

[@zfam7312]

Great video, where did you buy the pads? Can you pin a post ? I saw multiple people ask this question. Also you said use h202 to help keep clean . What ratio of that per gallon?

[@completegrowing5427]

You can buy the pads online "ZORO". The H2O2 ratio is 1/8 cup of 30% per gallon. Thanks

[@augiemanfredo1697]

Great Video! I have a 30 ft by 96 ft Greenhouse. If I make a 20ft length x 4inch x 5ft Height EC, would this reduce heat in greenhouse. Also, what size of fans needed to use at opposite end. Thanks in advance for your help.

[@greenhousesolutions1074]

2 each 36"- 48" fans, but 3 each of 24" fans would work and give you more options by setting separate thermostats for each fan.

[@varunagarwal3186]

Greetings from India. Love this video! I am making a very small greenhouse of size 16' by 10', height around 7'. The temperature in my area reaches a maximum of 95F and humidity is usually around 85%. What would be the best way to cool my greenhouse down to 65F? If you suggest using fan and pad, then what size pad and fans should I purchase?

[@greenhousesolutions1074]

With high humidity, you cannot cool down the greenhouse to 65 with evaporative cooling. You would need to go with window unit - refridgerated air.

[@flatout5815]

@@greenhousesolutions1074 ty this is what I myself worried about. Humidity and heat is my issue. Don't think the evaporative cooling system is for me. Running dehumidifiers would kinda bring the heat back up making the evap cooling system pointless.

i have a 10x12 x 8 ft greenhouse, high humidity in north florida, so from reading comments I would need refrigerated cooling to lower temperatures during day, what size unit would you suggest . Unfortunately this greenhouse did not come with automatic air vents. I do have 2 oscillating fans that I use, and take my orchids outside as soon as temperatures are appropriate. any suggestions are greatly appreciated.

[@rplatow4120]

We are very humid here in Arkansas as well. One 16 inch vent fan and a water wall will not get it cold, but will keep it from burning your plants. Should work better than you expect in that size greenhouse. We do not use any refrigerated air systems mainly because of cost.

Does the entire wall need to be covered plywood like that? Or can you put a frame to hold the cooling pad and then put the plastic on the rest of the wall? Also what size cooling pad and and exhaust fan would you recommend for a 15'x20' greenhouse in a hot desert climate?

[@greenhousesolutions1074]

The back wall does not have to be solid. Poly works great. (already have done a few like that) Just frame for your space. Thanks

Hey! Is it possible to use this technology for Mushroom House Cooling replacing the Air conditioning unit to the max? Note: Temperature in summers go up to 45 degrees C outside, and inside requirement will be of 20-25 degrees C. Inside requirements will be 80% Humidity which can be maintained by sprinklers i feel?

[@user-kl1nd1mx9x]

It is completely possible to use cooling water curtain and negative pressure fan to replace air conditioning, and groundwater circulation is adopted. It is possible to bring the temperature down to 25 degrees Celsius in summer. I suggest you install some more air conditioners, just in case.

[@seanray3333]

Does this work in humid areas?

[@rplatow4120]

Yes, enough for your greenhouse. Our humidity here is over 80% most of the summer. It does work better in lower humidity of coarse. Thanks

Why not put the reservoir outside? it would stay cooler

[@greenhousesolutions1074]

Plumbing, pump distance and drain more efficient inside. Water stays cool from the water that drains in from the cooler pads. Thanks for your input.

[@elisabethmutiara1758]

How much water wasted cost?

[@greenhousesolutions1074]

Water is not wasted, it is evaporated in the cooling process. Some days a couple gallons, other days 10. Still cheaper than refrigerated air. (or dead plants)

[@blunitehawk]

Estimated cost of project

[@greenhousesolutions1074]

The pads are the most expensive part. They will cost around $125. Total will be around $200 not including the exhaust fan. We are currently checking on purchasing everything in bulk so we can put a kit together to save everyone some money as well as the convenience of all the parts in one place.
