Id be grateful to know how many grams of MegaCrop V 2.5 are in a plain ole coffee teaspoon from the drawer.
Tough question. All I can tell you is 5mL = 1tsp so if you can find anything that has a 5mL mark on it then it will work. If near a dollar store you can grab a set of measuring spoons cheap as another option.
farside measures his teaspoon at 5g, where I'll use 6g as my reference.
