If your shadecloth is inside your greenhouse, the heat it blocks would be dissipated into your greenhouse. It would have a net zero effect on the temperature, but reduce the sunlight to your plants.
Except she's actually using this system and says it works. Maybe some of the heat stays between the cloth and the plastic and is radiated outward. Has anyone tried her method to see if it works? Repeat the experiment before denying.
The mighty string and grommet idea! I have been studying so many things and I know over thinking things, but the string and grommet is the most brilliant I have heard and will work wonderfully. In the summer I will use a shade screen on string with grommets as you propose, and in the winter, run strings half way down (grow toward the ground) and cover with a thermal blanket at night. Thank you!
@@SanDiegoSeedCompany Quick question. Is there a difference between the colors? I keep seeing black, green, and white; and none of the research I have done helps me 😂
@@yolandapierce4258 Great Question! Different manufacturers will make different colored shade cloth, the biggest factor is the precent of UV light that it blocks out. 70% blocks out 70% of UV light, while 20% only blocks out 20%, and so on. That's the biggest factor you want to consider. For vegetables, really anything over 50/60% is too much UV blockage and your plants will be stunted.
I would use shower curtain hangers and some type of tubing to have a track for it to move down. Possiblity of a solar power motor with a thermometer actuator for the switch to move it to shade the plants at the correct temp of the day
They make solar fans . or u could make 1 ur self with car radiator fan hooked up to a 100 watt solar panel.u can hook the set up 2 a temperature sensor that cuts fan on .hands free system really. Works off the sun
Dealing with the heat is one problem, but I've also been struggling with dealing with the swing to cold evenings during the winter, where the temps get low, and the humidity skyrockets inside the greenhouse, leading to mold growth, etc. Any tips for managing the temp swings through a 24 hour period (very hot to very cold), taking into account humidity? I'd be especially interested in solutions that may work for smaller, non-permanent structure greenhouses (the plastic ones that can be disassembled when not needed). Thanks!
From my tests on this the cloth is better on the outside and not touching the greenhouse itself cause that will allow heat transfer to the inside,, once the sunlight is allowed through the outer shell the heat is already in the greenhouse
I have the same type of greenhouse. It gets up to 120 degrees sometimes and thought about getting one. Is having it on the inside more efficient than the outside?
I don't know, I put it on the inside because I have a way to attach it. It gets very hot inside and even though I shaded my plants the heat was too much for them anyway, I could not cool it down enough. I ended up moving it where it got partial shade all day long.
The black was what was available in quality I needed and I like it over the white because it has less glare for the eyes and does not get filthy as fast.

I was going to say the same thing. It has to be on the exterior if temperature control is the objective.

Did not think about hanging the shade cloth and using clips. We just built my greenhouse and it is a learning process for sure. Thanks for the tip!
Happy to help!

It’s next on our list!
if you install the shade out of your greenhouse it would be cooler than current installation just because sunlight is limited out of the greenhouse
We have it both inside and out!
Carabiners on the string and grommets on the edge of the shade cloth. I used 4 bungie cords on each corner to keep it tight.
Great ideas!
Love that idea!

You can put a fan on a thermostat. Have it kick on at a certain temperature and pull cool air outside. We do that with a heater too.

My greenhouse is a pop up and I run the shade cloth on the outside of the frame on the inside, works great

Hi where did you get your thermometer? Thanks
Love ya shirt and greenhouse setup 😍🌺💜
Thank you. It's full of flowers right now!
Im in central Ca. Its hot in the greenhouse ? Thank You Im going to try shade cloth !!
Also a heavy duty fan will help. You will want to have windows and doors to open and let the hot air out.
Why not using white shade cloth?
The black was what was available in quality I needed and I like it over the white because it has less glare for the eyes and does not get filthy as fast.
Your shirt is epic!
Thanks! You can get your own! sandiegoseedcompany.com/product/tools-and-merchandise/straight-outta-compost-t-shirts/

@@SanDiegoSeedCompany sweet! Thanks
Hows the shade cloth going? U guys did the sliding thingy??
It’s just clipped to the side of the greenhouse. No sliding mechanism yet because we leave it up from July until oct.
Why You need green house there?
Because it helps with temperature regulation and holds humidity. We are a very dry climate.
