that is possible metal has weird shit in it as do nutrients if acidic enough metal can make hydrochloric gas as it is eroding people used to put tinfoil in muriatic acid to rock meth & to separate ephedrine from gualfasine it's nasty shit breathe enough of it you end up with high levels of heavy metals in the bloodstream there is a reason a lot of those old meth cooks look tore up the red phosphorous don't help either
O boy, sounds like some dangerous shit! I'm gonna have to buy a weighted air stone or figure something else out. No way I'm keeping that in my water. Shouldn't need it soon anyways, Il just let the water sit out for a few days instead of aerating.
I've also been thinking about setting up an experimental hydro system. Id keep it in the same tents as my soil.
A 3gal DIY dwc doesn't seem to complex and I should be able to rig I up for about $30
A bud of mine has been trying to convince me its easier than soil. An experiment im guna have to try,
For science...
