*Please note:  The wide span of seeds per gram within some crops is mainly based on variations of the seed weight of different cultivars. That means, e.g. there are lettuces that will have 600 seeds per gram and lettuces that will have 1,200 seeds per g and everything in between. Please treat the numbers given as approximations.
