Problems with saved seed
OK, so last year was my first REAL attempt at saving seeds from my garden. I have been growing all heirloom/ open pollinated for several years now but this was the first time I have really tried saving seed. This first attempt was, well...a total flop. I can't figure out what I did wrong. All the peppers and tomatoes were ripe, I let the tomato guts ferment like I was told to; I let everything dry completely before storing in envelopes in a glass jar out of the sunlight. I am getting maybe 1 plant for every 8 or 10 seeds sown. The only thing I can think of is that my AC went out when it was over 100, so my house was 80-90 degrees for part of a week before we could get the new unit installed, could that have effected the seed viability that much?
Any ideas on what I probably did wrong? How should I go about saving my seed this year?
I would very much appreciate some veteran seed saving advice!
