This Hemohim is some amazing stuff. I love it. It also addresses the issue you bring up. Please, connect with me if you want to get some.
Other than that, we here in LA saw a lot of rain in March, which is not typically a month when we get rain especially a down poor. It was neat because the skies cleared up with no smog around. And, since the lockdown, the smog hasn't really returned. It is pretty awesome.
Thanks buddy, I'll read up on it. 🙏
