i took prolly like 4 ounces of scraps, and used like 4 sticks of butter and it was def not as strong as id like...id say this, it prolly isnt going to taste good, so the stronger the better...id rather make honey oil and cook with that than make butter cuz the butter i made was green and pretty nasty... use a solvent method, described earlier to extract the essential oils out of the scrap material you cant do anything with...any solvent works, assuming its of high concentration, ive successfully made like 4 grams of hash oil off of the scraps of likke 4 plants, so i figure u'll get a gram per plant ish, depending on size and what not...but ya, id recommend seperating out the leaves you have which have trichomes, get the trichomes off, and then extract the remaining oils after... THC is NOT soluble in water, thus if you use a blender method, using ice cold water to get the trichomes off all of your plant scuff, then take take that scuff after you've removed the trichomes, you can then put that same material into a solvent, (93% isopropyl alcohol, butane), and extract the remaning oils and make hash oil; essentailly is the same process as making cannabutter but a lil different...if you don't know how to do a solvent extraction, id check out some youtube videos thats how i learned but it really isnt difficult
