I am growing in 50L (13gal) and 30L (7gal) containers. In the 'off season' I have been previously tipping my soil out so I can re-amend it, mix it, and let it cook/settle for growing in Spring time. Next grow I might go no till as I feel I probably now have a lot of good stuff in the soil already. I may just re-amend and lightly mix into the surface and just let the soil and the odd bit of rain mix it around. I have a resident worm population in my containers. The nutrient spikes that Rev suggests sound interesting, maybe that is a easier way to no till, to have some sort of refillable spikes to avoid disturbing the soil. My current big girl (a Godfather OG) was on water/worm wee only up until a few weeks ago, but even in a 50L (13gal) my feeling is that is too small to sustain that plant with water only so I relented and gave her a top dressing.Glad to have you along , I really like the sounds of what you are doing , would you say you are doing a no till big pot type situation? They guy at my local grow show started with the revs book and slowly moved to large beds large worm populations and has pretty much created a complete soil food web in his pots , I would like to dabble into something like that but I don’t have the space to commit to that. Maybe one day when we are in a bigger house who knows I would love to see some photos of what your doing , I will have to stop by and check your stuff out .
