m0useanswered grow question a year ago Anything can be used for edibles , the problem is the more leafy bits will suck in more of your base fat, MCT/butter.
Might be easier to freeze all the trim n knock off the crystals and then add that into the pot, or covert the whole plant into bubble hash then infuse that into the fat,
Most of the trichomes are on the flowers, good amount on sugar leaves and little on the fan leaves and branches.
Good Luck!
