This is kind of a continuation of my previous post about treating PM. (I can’t post links yet ). But after reading more about UVC light treatments for PM, etc I thought I’d make a post more focused on that.
A lot of what I’ve read about talks about how effective UVC light exposure is at killing bacteria, specifically PM, but the majority talk about how dangerous it is and that they are scared to use it, etc. I thought these type of lights were super expensive, which is why I didn’t start with this path, but I’ve seen more affordable hand held UVC lights. However, they all seem be only 3w and I’m not sure if it will be effective enough to kill this PM. If it is possible for a light with this power to kill PM, how long should I be exposing the plants to it?
From reading, PM needs to be exposed to about 1800 uW of UVC per square cm to be destroyed. Using an 11w UVC light, a quick once over (basically a second or so I guess) is supposedly enough to kill it. So if using 3w, how long of a light exposure is needed for the same effect? 3-4 times as long? There is a post on thcfarmer about this (again, no link).
As with everything, knowledge is key. UVC light is dangerous, but it looks to be extremely effective at killing PM without having to spray liquids all over the flowers and leaves.
Any knowledge and/or experience with using UVC light to treat PM is greatly appreciated. Thanks!!
