Reusing soil

sure.. best to sanitize in some way to avoid any carryover issues or something lurking that needs more time to be a catastrophe. Also, need to amend it again with various fertilizers unless you intend to treat it like a soilless substrate or know it has plenty of nutes remaining from your fertilization in flower etc.. either way, probably has a low nutrient content compared to new soil. i say that only to cover my bases. i reused my soil for 2-3 cycles before i switched to soilless. small sample. but shows it isn't a super high percentage risk to do so without taking any precautions... and common sense to not re-used a pot that had an unhealhty plant related to rootzone. One other thing -- the substrate breaks down over time. it will lose water capacity over time. if it can't hold water, it can't feed the plants. drainage qualities will change over time too as it breaks down more. Roots can rot, which invites any random microbe to get a foothold, carryover diseases you didn't notice, yet, and other risks are introduced when doing this. if you re-amend and sanitize it, it's not a risk at all, but just re-using it without any maintenance is a bad idea -- eventually it will cause a problem even if it takes years of doing it. always good to put things in perspective. for 3-4 plants it might cost 20$ for soil, but you'll spend 300+ on electricity. IMO, if it adds more hours of maintenance, i start to consider how much my time is worth vs how much i am saving. if the savings amounts to some paltry sum per hour, i'm going with convenience. just my 2 cents on that stuff. i was huge on trying to re-use and save as much as possible the first year... much happier since i moved away from that strategy, lol. Each to their own on that.

Hello, it depends in how much fertiliser you have been putting into your grows so either let the soil rest for a few months or mix it using 60 percent Old soil and 30 percent fresh soil, some perlite to have better drainage. i would recomend growing photoperiods in the reused soil, and transplant after seedlingsstage into this i would start a seed into new soil, because they like it quite poor greetings if you go with an automatic grow, delute the old soil at least to 50:50

You can, although not the best. Some resuse coco 4 5 even 6 times. You have to make sure the nutrients was flushed out properly last time and the pppms are very low. Also having recharge or equivalent would help with microbes. Reusing soil is OK, if it was flushed as well, same thing as coco. Just have to make sure it's not to hot for the babies. I would flush it until ppms are no more then 100ppms over tap water. My tap is at 120ppm. So 220-250ppms in runoff. If you can get it to that point then I see nothing wrong. It would be best to use new, but many reuse soil and coco over and over to save money. It's best to do it when not in need, so you can experiment. When your in a tight spot you could be risking alot. Adding perlite to your grow could help. Just 1 gallon of perlite or pumus split between your other plants. If you have 4 5 or 6 more plants then 1 gallon of perlite split between them wouldn't be that had and would help aerate the soil more.
