well for starters if it showed two carts it was the conversion for a 4gram kit, which yealds approx 40ml at a ratio of 75mg/ml if you use all of the oil that is provided. that is usually the standard mg/ml for the kits. If you wanted a higher ratio you would use less oil, but it may be a little more painful because the ba concentration would be higher. there are a couple of good post on this board about the different ratios. if it is your first time making it i would just use all the oil that is provided.
