As an Organic Bio-Dynamic grower, I have used horsetail tee for PM it helped but did not cure all the problems of the most susceptible varieties imported directly from Afghanistan and the surrounding areas. UV lights worked better like flower growers in Holland use in greenhouses.
To me the key is using Cannabis varieties that have a high natural resistance vs varieties that have very high susceptibility, think about it, do we really want varieties that have no resistance like many WLD Indicas and their hybrids? I suggest we breed solutions to our problems instead of masking them and increasing problems in the future by using such plants as parents.
Do you know the active materials in horsetail? I do not. Other then diverse alkaloids, nicotinic acid, silica.
