Believe it or not, there is no perceivable, visible difference which could be noticed by eye between the different kinds of cannabis seeds. Indica and Sativa, autoflowering, regular or feminised, finally – strains for cultivating industrial hemp – they all look practically the same. To assure yourself, that you buy a right and authentic variety, you should rely on tried and tested seedbanks only.
What about the size of marijuana seed? It can be as big as a match-head, as a small pea or as a tomato seed. The later size and health of the plant which will grow from it are totally independent factors. There is only one rule: in most of the cases Indica seeds are bigger than those of Sativa strains.
