What are some short plants that preferably could be grown indoor which have similar nutritional requirements (in terms of N-P-K ratio, doses etc.) as Cannabis?
The purpose of this is testing a mineral fertilizer for Cannabis, without actually growing Cannabis as it is illegal in my country.
I was looking into Cannabaceae family and found out that Hops are closely related. However, due to its size/height it won't be convenient to grow it at home. Also, I'm not sure if being in the same family implies similar nutritional needs.
Plus bonus for valuable/exotic plants.
