Thank you for the replies.
I’m planning to buy double-wall polycarbonate panels, either 6mm or 8mm. I’m also thinking of installing a water wall with an exhaust fan to keep the greenhouse cooler in the summer, and add heating for the winter. I plan to install an automatic roof vent opener as well.

I’ll be growing rare anthuriums and would like to maintain the temperature between 60°F and 85°F, and humidity around 65 to 75%

A nursery owner mentioned that polycarbonate panels provide excellent conditions for plants
However, I’m a bit hesitant because it will cost me a couple of thousand dollars.

Hello,

I built a small greenhouse(440sf ft) in our backyard in Los Angeles California a few years ago using regular greenhouse film to grow houseplants.

However, I quickly found that it became too hot and too bright inside—especially during the summer—for most houseplants. So, I applied shading compound to the plastic film and made other adjustments.

Over time, I noticed that cats were walking across the greenhouse, which caused small holes in the film. As a result, it started leaking during winter.

Now, we’re considering growing rare anthuriums in the greenhouse. Because of that, we’re thinking about upgrading it with polycarbonate panels as we’ve heard good things about them. (—6mm for the roof and 8mm for the sides—)

Could you let me know if upgrading to polycarbonate panels will significantly improve the greenhouse environment?
The product description says it has 89% light transmission and blocks 99% of UV rays.
Do we still need to install shade cloth?

Thank you!
