Round 2, here is a recap of what round 1 was like.
round 1
4-5 gallon red clay soil, 6+ gallon recycled last years potting mix, recycled peat plugs, partially decomposed roots.
large bag of "garden soil" with a tiny amount of NPK
2 gallon overwintered oak and maple leaves
1 pound roasted buckwheat and 1 pound spelt grain
2 cups jobes compost starter (Archaea inoculant)
cardboard strips, chainsaw curls, sawdust, hardwood ash
2 cups gypsum, 1 cup lime, 2 cups Azomite, 1 cup Epsom
water with hydroguard (bacillus inoculant) solution
turned in till the clay clumps 1/2 inch or less
turn a couple times a week, water sparingly
it should maintain it's own moisture in most environments.
Turn in the sprouts as they come up, let them yellow and struggle in there.
Turn in more leafy biomass whenever you want.
round 2 (one month or more later, most cardboard and whatever but sprouts should me broken down pretty good or gone)
1/2 bag builders sand, 1 brick fine COIR (pre-soaked in water)
2 cups Langbeinite, 2 cups azomite, 2 cups black hen, 2 cups cottonseed meal, 2 cups bone meal, 1 gallon vermiculite
2 cups jobes compost starter (Archaea inoculant)
turn in dry ingredients,
water with hydroguard (bacillus inoculant) solution
1 cup Jobes Bio-Zome fungal/bacteria innoculant
turn it over again, cover and/or leave out in sun
in two weeks, uncover the mix, turn it over again, and it isnow a useful starter potting soil mix.
At potting that is my base mix, and I adjust the final mix with one of several other mediums to get the effect I am after.
1. acid loving plants: add sulfur or aluminum to reduce pH to 5 and mix soil 1/3 perlite/coir/potting soil
2. House Plants: same as acid loving without the sulfur and aluminum
3. Vegetables and Berries: Same as House plants, add fish emulsion or Bio-Fish, eggshells or shell meal, Epsom, and either black hen/guano/blood meal, and a generous heap of pine bark.
4. Succulents, 1/3 sand/gravel/soil
This was designed to have organic forms of nutrients in the soil in multiple forms to fully mineralize the contents and create a base that has a high enough CEC to maintain fertility through several rounds of recycling. The more stages of decay happening at once the better.
I had those mycos laying around from planting trees, but for cannabis I would not use those. I always get the two kinds confused, but I am pretty sure it is the ENDO mycos that we want for cannabis, and not the ECTO's. Studies show the ones that burrow into the roots out compete the ones that surround the root and the positive benefits are reduced substantially.
here are several of those mixes, although not with the same batch of soil, this is an older batch. The new stuff from above will go in the grow room, I'm not wasting the super soil on ferns.
I hadn't repotted these in years, they were badly root bound, and the fern on the left was almost dead. I cut out 90% of its foliage. That and the Aloe may not survive, I chopped out some crazy root bound roots.
cant really see in the pics, the aloe has a layer of coarse gravel at bottom, It is 1/3 sand/fine gravel/soil, exactly.. The pics look heavier on perlite than they are.
