You either need to go with bigger pots or you need to use layers and spikes of raw nutrients with a well cooked soil. I could grow out a 2-3 gallon pot with the soil I have (you can even do it with a lightly amended commercial SS as seen in my previous journal) but I would have to make powerful spikes and thoughtful layers in my containers to do it and would have to be extremely vigilant about teas and balance. Spikes can contain things like blood meal, bone meal, and oyster shells, in 2 inch round holes made through the container from the top to an inch or two from the bottom. Powerful nutrients that are placed in specific places so the plant can access them and mine them on its terms, not being forced on its roots globally in the soil.
The smaller pots (below 10-15) require a lot more effort to maintain. Especially because I haven’t even mentioned carbon yet lol.
@Gee64 and I have had incredibly long and complex talks about carbon and it took a long time for such a simple concept I unnecessarily made difficult to sink in (6 months). Nowadays I keep a Rubbermaid bin full of coco outside rinsing in the weather for when I need to feed the microbes their fuel. Boom, simple concept
Or you could make an alright soil and use Geoflora. You’ll get additional benefits from a nice soil on top of GFs feeding regimen, and you can grow in smaller pots with ease. I would still recommend every mix you use, getting a few parts coco and few parts perlite in it regardless of whatever else you add. Those two items will drive increased growth on their own.
I’ve grown in small containers a few times on purpose to really test my ability to read the plants needs and rescue it because small pots are that finicky. They run out of carbon if not prepared correctly and the balance of bacteria to fungi falls out of wack very easily. It’s easy to underestimate just how much the plant and microbes will eat, especially if you’re successful.
Also, mulch your containers. There’s so many benefits to mulching your containers and relatively few drawbacks, almost all of which are related to the physical act of mulching itself lol. Mulch allows you to toss in some extra resources while allowing huge life to catalyze, it improves water retention, allows roots to grow above the soil line, and has a ton of other benefits I can’t remember because I just woke and toked
