The cheat sheet

Every size in grams

Cannabis flower is sold in fractions of an ounce. An ounce is about 28 grams, so an eighth is 3.5 grams, a quarter is 7 grams and a half is 14 grams. Single grams are sold too, mostly for trying a new strain.

Supers comes in three flower sizes: the eighth, the quarter and the ounce, plus an infused eighth of Sugar Shake.

Same flower, four bags

Every Supers bag is color coded, so the size is the only thing you have to pick. Red is Sativa, green is Hybrid and blue is Indica, in every size.

Bigger bags usually cost less per gram. That makes the ounce the value pick once you know you like a strain, and the eighth the smart way to try one.
