I want to sow some areas and wonder how much I can stretch the seed I have. Instead of counting 3.000 seeds of something, it would be easier to know on average how many seeds of each crop there are per grams (or in the US pounds or whatever you use). I have found some sources but they seem to differ a lot. I also suspect some of them are AI-generated, which makes them more unreliable. Do you know of a good reliable source that shows the most common vegetable seed per gram? ---

If I remember right Suzann Ashworth’s book “Seed to Seed” has that information for a lot of common crops. If you have particular crops in mind, I can look them up for you. ---

I would doubt there is any other way than to count and weight a small portion of the seeds you have. Not that difficult if you have high precision scale. Just about all seeds have probably around 1 to 10 ratio from lightest to heaviest. Averages in landrace context might work with a lot of seeds, but it depends what kinda population you have and what the source uses as baseline. ---

High Mowing Seeds provides that info. Find the crop, then look in Seed Specifications. They have given these numbers for many years, so unlikely to be AI (junk) [https://www.highmowingseeds.com/](https://www.highmowingseeds.com/) ---

Great tip. I have that. Been a long time I looked in it though. ---

I considered to do that. I just need a ballpark / some proportions while I’m planning the area of growth, to start. If I want more fine grained data, I might start doing that more. In any case, I can then compare the databases with my own measurements, so the sources help me. ---
