Killing mold on marijuana with alcohol

If you are going to go to the trouble of detailing each individual spot of mold with a q-tip, I’d use bicarbonate instead. Baking soda has extreme high ph. It will kill almost any mold/mildew/fungus. You can make solution, approximate 0.5% concentration when mixing 1 TBS per Gallon and keep this solution to dab on spots, much better than alcohol which could actually damage any trichomes it comes in contact with them. The bicarbonate solution can be rinsed off with pure water without any damage to trichomes, you can even mist a whole plant with this solution weekly, but you need to be careful it doesn’t get in the soil and you would want to rinse it off the plant the day before before a fresh application as you also don’t want it to continue to build up on the plant’s surfaces. It can cause a harsher smoke if you don’t get it all cleaned off with misting rinses of pure water after the mildew is gone, right before harvest. Rinse during the day with plenty of time to completely dry before dark.
