I have 100% germination of my oxi-clean processed tomato seeds from last year. That's better than any of the 7 store-bought varieties. It's easy, too - 1tsp oxi-clean to a cup of water, soak the seeds for 1/2 hour, rinse and dry. I planted extra in case they didn't work, and now I have too many.
I tried germinating in a windowsill last year and there was not enough light. I have a 2-tube fluorescent fixture over them this year.
