Im browsing some systems to get into some aero or hydro grow (still deciding) and found most of them to be PVC.

PVC has been proved to be carcinogenous.
They are moving growing to other materials like alimentary grade polyethylene.
Just wanted to shared it as ive found lot of posts here using PVC to build, and because most manufacturers are still using it because they dont want to lose their precious money and dont giv a shit about ppl safety.
