I gave Isopropyl alcohol 70% equal parts water, 1 tsp cayenne, kept enough for multiday application, what little population of aphids is left I shall catch them the next morning, opening the tent 10 min b4 lights on the clovers have yet to open, all the aphids hiding on undersides are easily visible, still none ever went near cannabis plant. Clovers far tastier it seems.
The alcohol kills on contact, the idea was to saturate the leaves with a light foliar application, and once I was done I ran it through the canopy with my hands making sure as much of the clover surface came in contact with the iso, once done turned on the fans and evaporate it quickly.
iSOPRO......ops caps . ... beautiful thing about Isopropyl is that it evaporates rapidly at room temperature way below boiling point leaving behind zero residual so nothing seeps its way into rootzones unless you spill it there.
Tis a magical solvent.
