Do you reuse soil?

So, I’ve harvested one of my plants, it’s drying right now. I want to start another one.
Can I reuse the same soil or should I buy new soil and perlite and start anew?

(It’s “terreau”, the usual soil we can buy in bags in gardening stores here, no added nutrients or anything. I did use nutrients to water during culture of course.)

Thanks!

In living soil, the soil is reused. There are special additives that you can mix into the soil to use it again. You should check online to see what’s available in your area

Do you mean I should look for a place where they take your old soil and upcycle it (but not for me, just so that I don’t throw it away)?
Sorry, the translation isn’t very clear

You can definitely reuse with some amendments. Last time I added craft blend by BuildaSoil, some worm castings, more perlite, and some compost. You’re essentially just rejuvenating the life in the soil and adding nutrients back in

I grow organically in living soil and have grow with the same soil for the last 3 years. If you’re growing with bottled nutes, you would have to fully flush your soil to wash away salt build up. It is possible to reuse the soil either way.

Yes you can reuse your medium. Depending on what type of nutrient you use will dictate how to proceed. If you use salt based nutrients, which is a lot of bottled nutes, you should flush the medium some so you start fresh again. If you are more along the organic route you can just reamend your medium. I’m on my 4th grow in the same medium and it has just gotten better every grow. I use 10 gallon pots with coco, charcoal , and worms as a medium. I use Gaia Green 4-4-4 and 2-8-4 with silica, microbes, and cal/mag added.

Thanks for your as sers. I’m still a bit lost though, probably because there’s a lot of vocabulary I’m not familiar with.
I used biobizz as nutrients.
How does one “flush” their medium, concretely?
Is there a full tutorial somewhere as to precisely what steps one should take?
Thanks

For example: for 4 liters of soil, you take 40 liters of water PH 6.5 and let it run through the soil.
After that, let the soil dry. Afterwards, you should mix new perlite into the soil.
When you replant, you should perhaps start fertilizing earlier since you have flushed the soil and it lacks nutrients.

As herr-green said you run a lot of ph adjusted water through your medium to rinse out the nutrients left in the medium. Some run water through until their EC or ppm is almost nothing. EC and ppm are a measurement of how strong the nutrients are. If you use organic nutrients you shouldn’t flush 1 bc organic bites don’t bind to water like a salt based nutrient and 2 you can ruin the microbiology in the medium in a couple of ways.

I also reuse my soil. On my third run right now started with a base of mother Earth potting soil added some peat moss, perlite, vermiculite, biochar, blood and bone meal, earthworm castings, then I throw a little of homemade compost in the mix. I don’t use bottle nutes I use Gaia green all purpose and the power Bloom as a top dress during cycles. Right now I’ve got my best looking ladies so far.

i also reuse my soil with the occasional new bag mixed in once a year and i use roots organics terp tea lineup but reammend with veg nutes,worm castings,essential earth, and ill water it in with recharge and a coconut water powder mix. pretty simple and can honestly say works well and i feel like has a good amount of microbial life

My way of using old stuff is a bit different to everyone else. I grow in coco with synthetic nutrients so I replace it after each run but the old stuff will be sat outside to get flushed by the rain for a few months and then mixed into whatever soil im using for veggies and whatever else we have going on outside at the time.

I’m using coco now too and going into my second run. You think that’s the best way to do it over flushing and reusing the coco? I don’t mind buying new coco, I actually just bought a second bag to mix in for my next run anyways, but would rather play it safe if you think that’s best?

I use Fox Farm coco, biochar, perlite, red wigglers, and Gaia Green 4-4-4 and 2-8-4. I add silica, cal/mag (both organic and salt based), microbes, fulvic and humid acids, with a pk booster in flower. Then I top dress every 3-4 weeks with the Gaia Green, I use both at all times but the ratio will change throughout the grow. In veg more 4-4-4 and then in flower I use more of the 2-8-4. I don’t do any flushing at the end I just remove one plant and put another in its place.

I do it that way just because after a 3-4 month run in autopots I have a very visible mineral build up at the top and I’m honestly just too lazy to take the time to flush it all back to almost blank.

lol I feel ya on that one! I’ll probably do the same
