+1 the sharp sand will carve em up, the myco will starve em and the traps do what they do best Heya itchy will building the bacteria in the medium with lacto or the like assist with keeping the gnats disinterested do you know?
yes & no
lacto are like the organisers , they get all the microlife pulling in the same direction then become food for that life , but the life needs to be there to begin with to keep bugs disinterested ,( plant health would be the best protection )
best microlife are the homemade castings or compost , made by you with microlife that live on your property & already speak each others language ,
IMO's = indigenous microorganism ,
checkout that Dan Kittredge vid , he pretty much sums it up , "a healthy plant does not have bug or pathogen probs" &
guess what , when the plants are really healthy , so are we !
Something to think about , What if these genetic markers they can find in looking at your DNA that suggest predisposition to whatever illness , what if those makers
are signs of lack of nutrition , your body is constantly renewing it's self , blood over a week , bones of several years , a large number of cells are renewed daily , so what would
happen if you weren't getting the required boron lets say & boron is the center of an enzyme that joins 2 links in the chain together that make your DNA , well that joining dose not happen
& they stay separated , it's this separation that is seen as markers for a predisposition to something , if we fix the lack of boron does that chain now become linked & DNA markers disappear ?
Sorry for going off topic Mr Jane
