Honestly I started with 2 tbspoon per gallon of 3% hydrogen peroxide. For two weeks I watered and occasionally sprayed the same mix. That did absolutely nothing except piss off any living pest ON my soil. Adults would still come around and lay eggs and eventually I will see little larvae after watering and adults fly out anytime I get near. At one point I almost lost the plant. I figured well shit, if I'm gonna loose the plant, I'm going to take my chances with peroxide. My environment and strain is most likely different from yours. So I would advise trying a medium mix first. Something like 12oz of 3% peroxide to 60 oz of water. Or 1 part peroxide to 5 parts water. If your plant doesn't show stress then try for a 1 part peroxide to 4 parts water. This is for 3% Only. Any other percentage will have to be diluted to 3% before using the tables listed.
Please please, I will say this. I am no expert and i have much to learn. Take it slow and keep an eye on it. Different strain and environment might take this solution differently then mines. Oh and habanero pepper spray with a tad of dish soap mixed with water will help keep aphids and gnats off the leaves for a short period. Adding neem oil will increase that short period. Good luck bro and keep us updated =)
