Mosquito Net to Control Caterpillars on Plants

So I've been putting some of my plants under mosquito nets to prevent caterpillars and it's working!

We have broccoli, cauliflower, and kale growing and it was being attached by caterpillars causing me to have to hand pick all these guys off every day (we do not use any pesticides or chemicals to keep the garden 100% organic!)

Here's the net I bought on Amazon:

Coghlan's Double Mosquito Net, White

I LOVE it. We have 4x4 posts at the corners of our garden so I just attached it to those. Otherwise, you would need 4 places to tie this off to, as it will not suspend itself. I've heard some people build a structure out of pvc...

Is it affecting the sunlight getting to my plants? Maybe a little, but they seem to be growing ok, anyway.

Best part? NO caterpillars at all!
