can you use old soil for seeds

I would not risk using old soil for seeds if the old soil is a bagged product that has been through a flowering cycle. Chances are it was flushed, hopefully, but there will be a buildup of something that could give you headaches not to mention the soil will probably still be too hot.
Yea..left over stuff..not so good...it's like you're living in someone old room rather than a new room for yourself and that rocks...your own room!

If you aren't recycling your soil you must like to throw away money. It gets better with age, as long as you know what you are doing.
Youre going to want to start your seedlings with a NEW seed starter mix in small cups, add some perlite & dolomite lime (small bag, cheap and easy)....when you repot em into larger pots THEN you can reuse your old soil...be sure to flush the heck out of it first, add some new perlite and dolomite lime and good to go...no need to cook it first...there are a ton of pictorials on this out there on this with great results, you can get six or more grows out of used soil so long as you flush it good first...same yield and no problems, why go through the hassle of buying/mixing/throwing away good soil every grow? it works, trust me...
Seeds I start with plain coco, I don't think seeds need nothing to start. After first true leaves plant in used flushed soil. Soil that has been flushed and maybe treated og bio, neem, or some prevention for pest Is a must.
but there is nothing wrong with using old soil as someone sailsaid it gets better with time.

In organic soil I would say yes, but anything that has synthesized fertilizers added to it I'd say meh. The only exception is if your soil is a heavily amended organic soil that has had nutrients fed to it from bottles; there's a few ways to get it back on track one of them being before you reuse add more biodynamic compost or ewc or both and feed it a tea with ful power or any humic acid (ful power is the best) and give it 3-4 weeks keeping the soil moist all the while. A can't recall where I read it, but there was once upon a time a study about microbes where some researchers infected a compost pile with radiation and 6 months later the microbes were still there and the radiation was not. The microbes wiped it clean. If microbes can do that, no problem for your situation. Just gotta make sure it's an organic soil that doesn't depend on bottled nutrients.
Depends on whether one wants to spend the time. I throw my money on the lawn, so it only helps, really.
But I do get and appreciate your point.
Couldn't agree more.
Around here you can fill a 5 gallon pot with mix for $2. I think I'll spend the $3 for $100 worth of seeds and avoid all risks. Even when I'm recycling. (don't do it anymore, just improve the lawn and outdoor run-of-the-mill plants.
