Ya DONT want to use "fan leaves"...rather, the leaves coated with 'trichs' (the white frosting) and the 'sweet leaf' in the buds is what ya need to use. You usually get this when ya trim buds. Fan leaves (w/o trichs) are a waste of time and very little THC/CBD content. These fan leaves should be trimmed off as you grow.
With the recipe given here, a 1 pound butter/1 oz trim/bud is a good ratio.
REMEMBER...you will only get about 3/4 pound budder than what you start with (this is common)....so, I like to put about another 1/4 trimmings into 1 pound butter batch. This will give you a nice potent budder. And, usually 1 stick budder to 1 batch (3 dozen) cookies...so you can get 96 (9 dozen) 2" POTENT cookies
As for giving medible to pets...NEVER! Its very CRUEL to do that to a cat, dog whatever! they cannot understand whats happening...just DONT DO IT!
...if a person DOES feed medibles to their pets, they should be SHOT.
just sayin...
