While organiks is correct, I'll add a little more.
You're recycling soil
If you're using less than 10 gallons you won't be getting results you should be getting. And that's at the smallest container. Best to use big container 30+ and plant multiple plants.
Recycling soil is good but again you won't see the results you want. But I'd recommended that if you don't wanna do no till.
Soil is complex, lots of activity, life and work going on. You need volume. You wouldn't compost or have a worm farm in 1 gallon. although you can, you're missing the boat.
Disturbing the soil is like knocking down a house. All the life inside soil had to rebuild.
Once you get your soil dialed in, you just top dress with neem and kelp a couple times year. Same soil for over 20 cycles! Bluejay is on 22 cycles
