Just wondering what th best string or stuff is too use? and aswell as how much space i should give them between crosses. Ive heard 2x2". Also how much room more should i give them more then grow area. As well as what should i use for a frame? pvc?
Any string basically works. I would go with something that isn't a really small diameter, as it could cause some damage to your plants possibly. 2x2 is fine. Any smaller and it's a pain in the dick. I think you're having an issue because there are too many options. Anything will work. There is no absolute best way to make a screen. PVC frame works just as well as one made from wood or something else. Use what is cheapest. There's no reason to spend 30 bucks on a fucking screen if you can build it for 6 bucks.
