I just blasted mine with 30 seconds of 22w of UVC which first came up in conversation in Shed’s thread, you’ll find it in its normal location, but it may have been instigated by CL?
Anyway - to get the PM it needs to be done after lights out because PM has a natural defense against UVC but its like some contrived Star Wars death star shield plot device - its only active whilst the sun is active. So 4 hours or so after lights out I zapped them for 30 seconds. The problem is of course - the light runs from about 90-430nm UVC, above about 300nm its visible. So yeah - light stress on the plants leading to hermies or not?
All these questions and more to be answered in the next episode of “How to fk your grow!”
Personally, I think - no way is it going to stress the plants enough to hermie. I reckon light stress is the least likely stress to cause hermaphrodite plants. Temperature/Humidity/diet I think are far more likely. In nature here we might get on certain weeks of the year electrical storms 5 nights out of 7. Lot of sheet lightening. All sort of lightning.
Its in areas like this cannabis sativa originates.
Anyway - wasn’t expecting PM anyway, we treated them and the tent is so bare the environment is way lower down but its there so I used it!
