to lower the viscosity, rosin is typically very thick. the best method i have found for solventless carts is to press the material very low temp on the 1st press giving a more terpy profile. the 2nd press is turned up in temp to pull more of a full spectrum profile the 2nd press gets decarb and then 1st press is re introduced to the 2nd press to help with viscosity and add some flavor. with this method most of the time i am able to add the oil into carts without any addition to change the viscosity
