The problem with trim/shake is it contains around 1/5th the THC of flower. Doing bubble hash is a lot of work and doing with trim you generally get low yield amounts compared to flower.
A lot of us cooked our trim (after decarb’ing) in coconut oil with a tablespoon of lecithin then strained the plant material out of the oil. Oil is then used to bake with or put in capsules. The problem with this method is it is inefficient extraction (leaves a lot of goodness behind) and it tends to taste very green or ‘weedy’.
Doing a cold extraction with ethanol pulls almost everything out and does it without pulling a bunch of chlorophyll from the plant material. I found doing a full spectrum oil with the Source Turbo produces an oil I can infuse into coconut oil to bake with and cookies are completely free of weed taste.
