I used both H2O2 to wash and lemon juice and baking soda together. H2O2 gets rid of any bacteria and cleans the weed. Lemon juice and baking soda react together foaming, they also change the Ph in helping to stop any mold.
I do an initial quick trim and break large colas down to smaller sections. With photo plants last year I had huge colas bigger around than a 1 liter bottle and as long as my fist to elbow. Tightly packed.
I would have to look it up but I think for H2O2 the ratio is one quart per gallon of water but I use two quarts to five gallon bucket of well water for wash.
Then I rinsed with water in a 5 gallon bucket with a cup of baking soda and a cup of Real Lemon. Then dunk in bucket of fresh water.
Then rinse in fresh water, shake buds and hang to dry.
About two days later I do my final trim and keep all sugar leaves trimmings for edibles. The edibles I make with oil such as olive or coconut oil get me more wasted than smoking just from trim.
I use a Magical Butter decarb box and then an Infuzium 420 to process the oil with trim.
