I'm growing hydro and after getting spider mites I am damn good at keeping them under control and/or killing them.

However, I wanted to get more tips on how to PREVENT them from even existing. I know the hygiene factors, everything must be clean, the atmosphere must not be too hot or too humid etc.

But what can I truly use in the reservoir to avoid having any spider mites, gnats, etc to even appear. :/

Thanks for all the help!!!
