Of course, I fully understand. It's just I'm a low-tech guy, so I've got no lamp, neither filters. By microbe-killers I meant rather some chemicals. Still, I avoided even that.UV filters do not harm plants.
Do you have any particular arguments to support this assessment? I'm not suggesting otherwise, it's just I don't know and would like to know better.the moment you dosed your traces, which are usually consumed by plants quite rapidly.
