Once it goes to seed, you only have two real options, harvest it right away. Or just let it go. Squishing all the seeds?! What were you thinking?
From the pictures, you have a large amount of seeds. Depending on the different strains, they might be fantastic seeds. It almost sounds like you had a full blown male in the grow room and didn't catch it. If so, the seeds could be really good. I say let it go and hope they are good seeds. Back in the day, the only pot you could get was full of seeds. You did need to smoke more than the stuff people grow now, but don't kid yourself, you could still get higher than a kite. People have the mistaken assumption that pot with seeds won't get you high. That is not true. My last seed project, where I got 600 seeds off of two small plants, after I dried and cleaned out all the seeds, the leftover pot wasn't that bad. It was really good for making brownies.
