Nice full-melt… If it don’t bubble it ain’t worth the trouble 
You have probably seen my bubblehash extraction.
@Baudelaire is right. I experiment a lot with volume of pail and amount of material. I don’t want much of the water column occupied by material, cause I’m afraid that trichome glands will became “captured” inside of the mass… I want it only say 7-8 cm high (and still 70% of it being ice cubes). If it is more, I remove the material or use wider diameter pail.
And btw I’m always using trim and I’m drying the material same way as top buds. Once dried I pack it up and give to freezer before actually mixing it.
