Decarboxylate your weed by spreading your coarsely ground cannabis evenly on an oven tray and wrap with tin foil.

Place in the oven on 240F/115C for 35 minutes, and then let it cool for another 30 minutes without taking of the tin foil.

In a mason jar, create a solution of 21ml Vegetable Glycerin and 9ml of Propelyn Glycol, using a syringe for exact measures.

Place your decarbed cannabis in the mason jar with the liquid solution and shake/swirl well.

Place your closed jar in cold water and let it come to a boil, Boil on low for 2 to 3 hours. Shake/swirl the mason jar every 30 minutes.

Use a pantyhose, shrimp net or fine sieve to press out all of the liquid.

Collect liquid with syringes and place into the dropper bottles.

Add any flavourings your might want to add (optional).
