I suspect I really should have done it sooner but I didn't. Still my tomato and pepper seeds are now in the potting mix in trays and ready to begin sprouting. I don't really have anywhere inside to put them in light or warmth other than whatever temp the house is. So I just have to set them out on warm days in the sun and bring them in at night. I suspect this will delay the sprouting but it's what I have to work with.
I dunno if all will sprout but I have WAY MORE seeds in the two trays than I will have room to plant them really. I'll be eating fresh green onions real soon as they are growing fast.
