CBD Terp Tanks are made using the purest available CBD (All of our products are!) and strain-specific terpene profiles from XJ-13 and Wedding Cake to our new terp sauce carts (More to Come!) which have their own medicinal value and strain-specific characteristics. Each 1ml cart contains 300mg or 500mg CBD and less than 0.3% THC. These are all now sold in disposable cartriges for ease of use.
