I've read not to. The article I read said that if the plant was sick somehow the problem would spread to the new plants through the decomposing roots. But I guess if your plants were healthy it wouldn't matter. I would thing any nuets left in the roots would leach back into the soil. Idk though.

I reuse it
I add more rock powders
25% happy frog and soak it down with microbes like Bush doctor.
Let it work in a warm spot 65> four weeks
I use 30gal tubs with a lid.
After three rounds it goes in a raised bed outdoors for lettuce.

I save it for summertime outdoor grows and mix about 50-50 with new.

update i checked with local growers who grow inside and they put old cannabis soil in a worm composter to be broke down with kicthen scraps. then use after 90 days

they said just add 10% more perlite
and 30% new soil

A friend of mine loves it. He tills in old soil into his outdoor garden. I get free vegies this way.

When you live on a lake and just have sand, that "used" stuff is valuable, not saying everybody should use it but I do

If it was organic I can't see why not, flush it really good. Mix in organic nutes of your choice. Sit for a month. There you go. Lol soil outside is renewable I can't see why your indoor soil would be different.
