Assuming you mean the shade curtains around 6:27, this is the shade curtains that come with the Janssens greenhouses. It uses specific hooks and clips. We made a Short video explaining how it works a while back: ua-cam.com/users/shortsuL5qp3WKXMc?feature=shared
You can always put a Riga on a stem wall to increase the height by a few feet if that's enough. The Janssens Gigant (greenhouseemporium.com/products/janssens-gigant-greenhouse/) can go up to 12.75′ at the peak. It can be ordered with 10mm polycarbonate. Otherwise, we don't offer higher models. It would be a custom configuration at that point.
As far as I can tell, they use 6mm polycarbonate which is still a bit thin. We recommend at least 8mm if you intend to grow during winter. If you're only extending the growing season (early Spring and late fall), then 6mm might be enough (but make sure to caulk all panels so they stay in place when it's windy). As for the yellowing, I cannot tell because we don't have experience with these greenhouses. I couldn't find any note that they are using UV protection or anything to prevent it. That doesn't mean that they don't do it but I'd ask them specifically if it's one of your concerns.
@ghemporium Thanks for the info, I appreciate it. I'm in St George, Utah zone 8b & our winter so far the coldest got down to 22° F. Still pretty cold for 6mm I'm sure. Not sure if I'd grow in it all winter, but might in the future. I'm growing my Fig trees in my garage now as it's already heated as I work in there. And the figs are putting on growth & the Mango I planted from seed is already 10" tall. I plan to put the figs in ground in the Spring, but may need to grow my mango tree another year before trying that??? Either Greenhouse or Garage again 🤔???
@@MatthewsFabrication Sounds like you're in a similar climate to us here in Central Texas! For overwintering plants, you likely don’t need much thicker material (I've seen a lot of people just use portable greenhouses for that). That said, you’ll definitely need a heater for those colder days-but keep in mind, with thinner material and potential gaps, it could use a LOT of electricity due to the lack of insulation. Make sure your greenhouse has auto-openers on the vents to prevent overheating if it warms up during the day. Also, the more plants you have in there, the warmer it will stay overnight, so you may not need to run the heater as much compared to if it were nearly empty. As for the fig, cooler temperatures might actually help it enter its dormancy phase, so a spot outside the garage could be ideal. On the other hand, the mango will likely thrive in the warmer garage setting since it loves consistent warmth year-round, especially as a young plant.
@ghemporium Thanks for the info. Still debating on a greenhouse or not. Fig trees don't need to go Dormant or need chill hours to produce more figs like other Fruits, like Stone fruits, apples, etcetera. My garage stays around 68-70° at night and 72-78° during the day. I have tons of LED 5000k light, plus high-quality grow lights. I know it's not the same as the sun, but they're pushing growth & I have about 3 months before planting in ground. The mango is just for fun, but if I could make it work outside, that'd be awesome.
@@MatthewsFabrication I learned something new about figs - thanks for sharing that knowledge with me! It sounds like your setup is quite great and successful. If I were you, I'd ask myself the questions: Am I going to use the greenhouse after Spring when the figs are in the ground and if the the answer is yes, how am I going to use it? Is it for more warm-season crops in the winter? Is it just a seasonal fling? Going through the hassle of setting up a greenhouse for a few months, makes no sense especially if you have such a good setup already. If you want to grow more in a greenhouse over longer periods, I'd highly suggest getting a good one so you can use it for many years to come without much hassle or outrageous electricity costs. I hope this helps a bit more with your decision!
Im getting a greenhouse /shed builder building me a 8x12 greenhouse with poly ,to be delivered to my house the 16th,im nervous now cause i, gonna put 4 barrels 55 gallon drums painted black in it,,,i read u could take alot off electric using the drums , but still need some kind of plug in heater, can you help me here ,? appreciate any advice you can give me, the temps drop in 30's next week, i have plants in a 6x 8 shelter logic at the moment till wed. Thanks..
You mentioned that UV light is harmful to plants. I'm not sure this is correct. If it was the case that UV light was harmful to plants, there wouldn't be any. I actually think the opposite could be said... that natural UV levels are healthy for plants. I think polycarbonate could be improved if it allowed more UV light through. That being said, polycarbonate sheets are still good options for greenhouse glazing.
You’re absolutely right that plants have evolved to handle natural UV exposure-UV-A can even have beneficial effects like boosting pigmentation and stress tolerance. However, excessive UV-B (a smaller but more intense part of the spectrum) can harm plants by damaging DNA, proteins, and photosynthetic processes. Plants often adapt with protective pigments, but in controlled environments like greenhouses, we use UV-blocking materials to minimize stress and maximize growth. By the way, we’re actually working on another video about this topic! We had a similar question and thought it would be great to dive deeper into “light in greenhouses,” including UV light and how it impacts plants. Stay tuned! 😊

Nice tip about caulking the polycarbonate to reduce panels rattling in the wind.
My guy, your moustache is top notch, also the info is very informative.
Thanks so much! The moustache appreciates the love, and I'm glad you found the info helpful.
If it's passing light through, it is not opaque. Light diffusing panels are translucent. Opaque does not allow light to pass.
Good catch! Thanks for clearing this up.
Could you explain the drapery behind you at the end of the video and how it is applied?

The word is translucent. it's in between opaque and transparent.
I need something a little larger than the Rigla to grow dwarf fruit trees. Any ideas?

How does the Polycarbonate on a Howe brand Greenhouse compare? From Amazon?
Will those polycarbonate panels yellow?

The better word you was asking for is translucent

I answered your question on the other video you commented on.
I think the words you’re looking for is translucent
Snap
useful thnx

I honestly want to make a tiny house with polycarbonate
That's an interesting way to use polycarbonate. Feel free to share your journey with us!
Translucent, the word you're looking for is 'translucent'
The word would be opacity
Just purchased a polycarbonate greenhouse not like the one your in nice
