Chicken wire is used more then most and is fine. I build units that use a 2" square steel mesh and fine that works the best. I use the non galvanize wire and paint it white with an anti-rust type of paint. The galvanized steel may leave behind led because itā??s used in the galvanized process as a bonding agent in most countries. You donā??t want to smoke that shit it will kill you over time. Make a wooden frame and use staples to pull it tight. The idea of a see of green grow is lots of small plants growing in Hydroponics and you flower them from clones once they reach about 12ā? tall. The screen is placed about 6 to 8ā? and no more then 12ā? above the canopy. I got my camera fixed I hope so I will try to get you some pictures when I make my rounds later and check up on some of my friends.
