Ohhh WOW!!! To tell you the truth, the past week I’ve been talking myself into trying another hydro run. And I kinda settled on soil/coco but I’m try a single hydro setup until I can get more experience and knowledge on hydro. But I truly feel I would do much better with soil. So this living soil. You grow your own worms. And as they poop you mix that with a good soil (Ocean Forest, or Gaia Green) or do you mix it with straight coco?
Pre-edited: sorry for the ramble, High as Fuck... separated it into bullets you can piece together in whatever order makes sense
I have what started as a peat-based mix. But I got come coco bricks to use as worm bedding so some of that gets in there.
What I liked about the "take-n-bake" kit was it showed up in about 7 different boxes with over a dozen components all in the proper ratio. I know exactly what is in it. I can now make my own.
$300 got me ~70g of soil. One month of resting after mixing, soaking, then letting it dry out. No worms or anything for that month - which made it a great time to get a worm bin started. Started last summer and I have more soil than I need right now.
A handful of worms will become hundreds in the pot easily. If you can keep a worm bin you can let a plant grow in it. That is basically my theory.
The starting "food" in the soil was a Clackamas Coot's mix of natural stuff, but once your plants are going it's all about feeding the worms and microbes.
I have a cover crop that I "mow" every watering. Each pot is like a little tree in the front yard.
It came with compost and castings which is what starts changing the dirt into soil, but as you add mulch, and castings, and top-dress you add soil volume over time.
