  1. No roof on earth. Wtf was that cartoon@ the beginning with earth having a roof… around a ball. Lmfao. The only way you get a greenhouse effect is with a roof. Just saying👍good video.

  2. Modern agricultural intelligent glass greenhouses achieve the most suitable temperature, light, water, steam, fertilizer and other conditions for the growth of plants in the greenhouse by adjusting the shading system, ventilation system, ventilation system, cooling system, and heating system of the greenhouse.

  3. NW Arizona gets triple digits 3 months in summer; my 12×16 greenhouse hasn't been through a summer YET, because I just built it (October). I plan on using shade cloth in summer and have high-level vents along the top 1/3 of the wall on the NORTH side of it, and east and west sides have windows with screens; I also plant to have grapevines planted outside that will shade the greenhouse in summer but drop their leaves in fall for sun light in winter. I hope all that works. I have no money to spend on AC .

  4. I like the earth tubes idea. Is there a way to control the temperature tho? Maybe with a automatic temperature sensor on the fan to control the fan speed?

  5. I'm thinking of building a Shadehouse on my terrace, Winter temperatures are not an issue here as it doesn't go below 16C at all. But the Summer is super super hot here. It regularly gets to 40C for 1.5 Months and can reach upto 45C for nearly 2.5 weeks with humidity at 19-35% during the hot times. So does using 50% Aluminets, Foggers and/or ultrasonic humidifiers and Ventilating and circulating fans allow me to get down the temperature in shade house below 34C for growing orchids???
    Is this even a good idea??

  6. With a stirling engine using the excess heat or a steam engine with alcohol or some other refrigerant mixture which boils above the temperature you want to keep the plants at and which uses the excess heat, both could be used to run an AC system to cool the greenhouse. Unfortunately, those things are not very popular (yet). And maybe sunscreen can be used inside the greenhouse's windows/film to reduce the heat from the sunlight, and a light pressure washing would wipe it all out. if the sunscreen is non-toxic and biodegradable, then it could be washed off without issue at any time, and if not, just cover the plants with some waterproof tarps, and wash away! Sunflower (cooking) oil has a SPF of 15-19, if you're interested.

  8. Ironically I am in the window film industry. I manufacture High end Ceramic films that are virtually clear and yet they block 90% of the infrared spectrum. I am thinking about building a glass greenhouse now. Apollo Window Film Ultra Sky Series 73% VLT 90 IR We use on windshields and entire vehicles when you want performance and still see. Can also be used on residential or Architectural Windows. The old adage You dont have to go dark to block the heat anymore!

  9. Problem with too much moisture in a greenhouse is molds and mildew. If you were to use water for cooling you'd need to ventilate and other ways to prevent mildew like using sulfur.

  10. Sir; when using "Geothermal Cooling"; does they use metal/pvc pipes?? Otherwise how it would exchange heat with earth efficiently? If yes; then how do they they make it corrosion-resistant?? Please enlight. Thank you!!

  11. Hey Boss! How about cooling a greenhouse, in Coastal areas, where avg temperature is around 27 Celcius and humidity is around 80%. Your reply would be appreciated. Thank you.

  12. Hy Grand Master Greenhouse, Was wondering if you may have any sugestions on a 1200square meter greenhouse with invidual 200square meter rooms and on top of the it all has to be seald for GMP medical use. Would you have any sugestion on an efficiant and sustainable method?
    Money ist not realy an issue. Looking forard to hear from you

  13. I would like to design and build a special greenhouse for plants two zones greater that mine. I want to put a brick fireplace on the North Wall, passive adjustable vents on the East & West Walls, and a door on the South. I also want a height of 12 feet. What do you suggest?

  14. I have what I call a greenhouse, it's actually not a greenhouse. It's kind of a more sturdy, overbuilt hoop house covered in Nylon mesh rather than a solid plastic sheet covering. In the very hot and humid climate of central Thailand I am always on the lookout for some economical method of cooling. I use 40% shade cloth to protect the more sensitive plants and wonder if fans would offer much in my circumstance. Evaporative coolers wont work given the open airflow of the mesh covering. I am already at about the same temperature inside as out so I assume there isn't much more I can do given financial realities.

  15. Hi If you don't know about biochar. Yet tell everyone that you know very very good videos thank you very much keep up the good work videos are awesome do you know about biochar feed it to the hogs and cattle and goats it goes through them and helps the soil im from northern Kentucky look up the history of biochar for gardening tell everyone you know passed it on it's good for bad clay soil ok for good soil barn wood to char douse it with water then dry it out then activate it with worm castings or compost liquids first I also like rocket store Mass heaters couches and earthships homes are nice too look up sand to gold very interesting it's for deserts growing have a good day https://youtu.be/c5jvFbQYybg

  16. Had a private greenhouse in Saudi Arabia. We grew orchids. One thing we used was called “desert coolers”. It sucked in the humidity and cooled the moisture by blowing air through it. Then blew the cool air out thus cooling the greenhouse down and taking some of the humidity out at the same time. We did use shade cloth also. It was a glass greenhouse. Average outside temperature was 118 F. with 98% humidity.

  17. Great share, do you think these techniques put together will work well for a Mediterranean climate? In a way where we can spend time inside all year long for work and resting? Of course along with growing alot of plants and having Aquaponics system.
    Any other recommendations?

  18. So if you limited the spectrum of light passing through the window tint to only allow red and blue. When you were inside , although you should find some reduction in heat, your plants would appear black, and thus would become very hard to care for since most things we identify with our eyes, such as funguses or any other fine detail that might be lost under anything but the best lighting conditions…… that being said you see that kind of grow op all the time in tent growing with a set spectrum led setup, so it is quite feasible that you could train your eyes past it.

  19. Thank you so much for sharing. I am first year greenhouse growing in my back yard. I just lost all my seedlings when the sun came out one day during 20 degree weather and I was at work. My greenhouse reached 119 degrees . killing all my seedlings. I started all over. Please come check me out when you can. Join if you like.

  20. They also make variable tint films .. there are window films that vary in clarity like a dimmer switch can vary the amount of light from a light .. soo in the summer when you want less you tint more light out , and in the winter when you want more you tint less light out .. As pointed out in the video this reduction in sunlight .. like any shade cloths or conventional tint , would reduce the sunlight to the plants as well , as the heat .. Variable tint films are more expensive initially than either the shade cloths or conventional films .. but do provide a convenience of being able to very easily and quickly change the amount of shading .. of course there are others .. here are a few example links .. https://www.raynofilm.com/smartfilmhttps://www.smarttint.com/ … also .. white type of reflective is more effective at reducing interior heat than black / dark absorbing .. the black / dark will block light , but it gets hot as the dark surface itself absorbs that light energy .. The dark is often used in mobile applications for our human optic system to more easier to still see through that tinted layer .. although there could be aesthetic reasons to want this in a stationary application (like a green house) , it isn't as necessary as it is in mobile applications , and thus the better cooling effect of reflective will have a larger edge in the non-mobile application.

  21. Hey,
    Once again I'm here with my strange ideas. And for this I'm thinking of using a solar heater in the greenhouse (but taking "cold" air inside and giving "hot" air outisde).
    It's not a perfect solution and will not cool the inside but it could be enough for where I live to keep inside to an acceptable temperature (+ ventilation at night and/or earth tubes).
    What you think? :p

  22. Tubes length is primary for transference, transference efficiency can be increased but I want to try it before I add my idea to this mix of brought together info. Efficiency talks to running Geo without compressors like ground source heat pumps utilize but using a compressor takes away the real efficiency in electric costs. Need higher transference, think I might have the answer but am not quite there yet.
