The number of seeds provided for each variety differs based on several factors.
We examined per-capita food consumption statistics, average varietal yields and expected germination rates. Then we accounted for a certain amount of loss due to climactic events, pests and other problematic situations. Ultimately, we came up with a given amount of seed for each variety that would provide an abundance for the number of feeding units each particular bank is rated for.
It should be emphasized that our per-capita seed counts were based on the assumption that the harvests would be less than stellar, and certainly not bountiful. For example, we figured that a single Hales Best cantaloupe seed would yield, on average, two cantaloupes; similarly, we figured that six Texas Big Boy pea seeds would yield only one pound of peas. In other words, we were overly cautious in our assessments.
It should also be noted that micro seeds such as carrots, mustard and celery are supplied in numbers exceeding actual need, simply because they are small and difficult to work with. (On the other hand, we don't use this type of seed to artificially inflate the seed count in our banks as some of our competitors do. It would be very easy for us to put 5,000 celery seeds, 5,000 carrot seeds and 5,000 lettuce seeds in our Piggy Bank, thereby inflating the total seed count to well over 25,000. But we don't play those games.)
Suffice it to say that if the seeds are cultivated according to the instructions given in the books we sell, you should have enough for your family with an abundance to share. And remember that at the end of each growing season, you will use this abundance to replenish the seeds taken from your bank.
So to answer the question, the total number of seeds in our banks ranges from way over 10,000 in the Piggy Bank to approximately 200,000 in the Treasury. Again, any seed you reproduce in your own garden should be saved properly and used to replenish older stock.
