The Farm to Vape (FTV) Key Lime kit is designed to turn your herbal concentrates like wax or oil into liquid. The Farm to Vape Key Lime Kit comes with 10ml of FTV Key Lime flavored Thinner and a boil-able glass dropper bottle for mixing/thinning your concentrates into the perfect liquid consistency. The revolutionary FTV dropper bottle boil method makes thinning wax and oil quick and easy. Just place your concentrate in the dropper bottle, add two to three times as much FTV Thinner as you did concentrate. Close the cap. Submerge in boiling water for three minutes (caution this oil will be hot, this should go without saying, but we are saying). Done, ready to use! Itâ€™s that easy. FTV Thinner is made from our proprietary blend of U.S.P. Polyethylene Glycols PEG 400 and PEG 300. Made and bottled in the USA.
