Great video. I’ve never seen anyone else present this material.
Glad you enjoyed it!
ANOTHER EXCELLENT VIDEO! THANK YOU!
Our pleasure!
Very informative..Great camera work too. Thank you.
You guys rock!! Thank you so much!
You are the best 👌 just what I was looking for.
fantastic!
Nice video! Greatings from Mexico
Hola and thanks!
....Michigan Zone 6 hello ..
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.
For that cubic feet use a 24" vent fan and 60"x34" opening with your cooling pads.
@@greenhousesolutions1074 Thank you
I have a 20’ x36’ high tunnel
This is great!
great video thanks for sharing .what size would you recommend for 20x96 hoops.10" center height with one 4 foot fan at rear a few stir fans along wall. Do you have a material list as well a source list for this project. were also in humid climate where humidity will need to be controlled at times any extra thoughts appreciated. Wish I could just buy the kit!
Great!!!!
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
Would you be so kind to give me your material list? You have a great build. Thanks
How do you figure out how big of a water wall you need for the greenhouse ?
This was a great video. We just built a 20’ x 53’ x 13 1/2” high tunnel. My plans are to add an evap cooler. I was wondering where you ordered your pads?
Thank you,
Ronda from Merry Noise Farm in Elmo, Texas. :)
ZORO has been our best for the pads so far. Thanks for watching!
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?
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.
It is recommended to know about thermal insulation cotton curtain (manual) and windproof rolling curtain (manual and automatic) for thermal insulation in winter

What are the cooling pads made of
do you know what is the water consumption for this scale of greenhouse?
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?
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.
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.
Full video shows the float etc. I use a timer on the pump for the cooling pads. Depends on time of year/temperature.
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.
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.
Where can I order the cool cell holder? Thanks
GREENHOUSE SOLUTIONS: For beginners like me, could you please post the
right order to watch your videos on the DUTCH BUCKET SYSTEM & FLOAT
BED GROWING SYSTEM along with Complete instructions and where to source
everything we need? Thank you.
Great idea. Watch for "newbee" videos. Thanks!!
I live in SW Colorado... we get cold, snow and icy conditions here in winter. How do I take care of my evaporative water wall here during winter? Thank you for a great video. Very helpful.
I put plastic on the outside and then screw on a piece of plywood to the outside of that. Inside I will put a sheet of insulation board over the pads. Works very well.
Thanks
@@randyplatow2643 Thank you very much.
Does the wet wall have to be on a window or open wall? Can it be against a solid wall? Thank you great vids.
You can use inside air for smaller units, but for this size, open to outside air is best.
Thanks
Does it have to be in an opening or could you build a freestanding frame and have it inside the greenhouse
Would it be better to point the holes upwards so that the water flows out and over the top of the pipe?
Tried that. Works best down. Water flow and and even pad wetting better pointed down. Thanks
where can we purchase the wetting Panels? I did not find them on your webpage
Nice low cost solution for a work shed also. Do you add bleach or such to the water to avoid slime and keep water clean ?
Yes. You can use H2O2 as well. Thanks
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.
Still helps a lot. Just works better at lower humidity. We grow all summer even with high (85%+) humidity.
Shade cloth works way better outside the poly. Keeps the poly cooler as well.
Why the shade cloth on the inside?
Also, I thought AZ was very low humidity ... how would the dew point get high?
@@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!
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?
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.)
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.
Great info - thanks for posting the detailed video. The rain gutter perimeter is a great idea.

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?
With high humidity, you cannot cool down the greenhouse to 65 with evaporative cooling. You would need to go with window unit - refridgerated air.
@@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.
How much do those swamp cooler pads cost?
Can you post links to the pump and pads suppliers?
We do have the pump, pads and fittings at www.completegreenhouse.com but are still working out the best way to ship. The company ZORO is where we get the pads and everything else are hardware stores and amazon.
Hi, I have a question which is, how many of those cooling pad can I run with a water pump with power of 1HP
Depends on the pump GPH, how and high it needs to pump (head). That being said, you should be able to do at least 24 - 1 foot wide pads. Thanks
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?
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
24" fan and 5' x 3' pad opening- exactly like the video.
Thanks
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.
Yes, absolutely. The cooler water is a plus!
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.
@@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?
Thanks for the video. Does this system good for 130-140 degree?
Yes. Especially if it is in low humidity
@@rplatow4120 Thank you.
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?
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.
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.
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.
thanks so much
When getting a shade screen for my green house, which is better, a black one or a white one?
Black blocks more. 30% best for flowering plants (tomatoes etc.) 50% can be used for leafy - spinach, lettuce chard. Thanks
How thick are the pad on the video
4 inches. Still get great air flow and plenty to cool.
What kind of water pump? Utility pump or sumpump
Either one, Just need the right size for your system. We use 350 -400 gph on this size.
Dont you need to monitor humidity too?
Humidity can be a problem, but with enough circulation (fans) inside, we have had no problems.
Thanks for watching.
Does this work in humid areas?
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
Whats the name of the pads and where to buy?
These are commercial evaporative cooler pads. Found on ZORO, but we buy in bulk, split and cut to size.
@Greenhouse solutions, what’s the dimensions of those pads?
Why not put the reservoir outside? it would stay cooler
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.
How much water wasted cost?
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)
Estimated cost of project
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.
Greenhouse Solutions thank you so much for your response! We are putting a buisiness plan together for a small mom and pops hemp farm. This is such valuable information❤️

What’s the size of your greenhouse
We have 18'x 24', 18'x 36' , 10'x 12', and 26'x 72'. The size determines the fan sizes and "wet wall" size. Full video on sizing coming soon. Thanks
You could eat dirt and call it a Beto oRoark impression.
I like it!
This would be a better video without the clowning and the stupid and political nonsense. Just stick to the point. Otherwise a good very informative video.
Just having some fun. Must have a sense of humor!
