@SillyHippy not to turn the thread into a living soil only discussion, no intent to highjack a thread so now that i have time to type let me share what i can.
TL;DR - if cost efficient is your means i would personally buy Fox Farms Ocean Forest (FFOF) and small amount of supplemetal nutrition, or cheap organic garden soil and a higher amount of supplements. Meaning I have seen FFOF give very similar results to plants as KIND soil, though you may have to feed once a week supplement the last 3-4 weeks of flower. For more details, read on.
In response to your original question, i haven’t heard of a lot of those specific names, but i did read one or two threads on someone growing with Kind soil, not sure if California Kind, but it advertises its all you need, just water, and it’ll take you all the way to flower. It worked well for them and it did seem to provide enough nutrition for the whole grow. They seemed to indicate that Kind recommends a certain maximum veg time which makes perfect sense. I recall looking up the price and if memory serves it was roughly double what Fox Farms Ocean Forest is at my local garden supply.
To put that price tag into an actual value, ive used Fox Farms ocean forest quite a bit. I love the stuff. I would consider it a high end soil, and price reflects it. What sets it apart from the others i’ve tried even to this day, is its out of the bag amazing drainage and aeration ability due to its physical makeup. Also its built in nutrition, and this is a two fold answer for me. One, FFOF (what you’ll see it called in shorthand) has enough nutrition to make it well into flower on a same sized container and veg time as the kind soil. I may have had to feed after week 5 or 6 of flower but that was after a 2-3 month veg. Thats not nothing.
And secondly the nutrition comes from good sources, oyster shell, bat guano, earthworm castings. Its easy for a soil to have long lasting nutrition when it comes from chemical salts or synthetic means. Much harder for it to have long lasting quality organic nutrition. The organic concept become more important to me as time goes on, even on my first grow when i was struggling with pH meters and liquid nute feedings charts i raised an eyebrow when the charts all recommend to flush the soil 5 times before i harvest. Why? What’s in it that needs to be so aggressively flushed out? And why would i want it anywhere in my garden? Remember flushing a container is to flow 3 times its capacity through it i think it is, so 15 gallons through a 5 gallon pot.
So i say that to present this - How does Kind soil create this nutrition? This i do not know. If it is chemically based i would immediately rule it out.
If it is safer and more sustainable, i would compare it to Fox Farms where FF is roughly half the cost though you may have to add a supplement the last four weeks of flower or so, depending on plant size.
I just learned they sell living soil and i’m skeptical. But i’m skeptical of everything at first. I just read last night that its important to plant cover crops like legumes or clover in your living soil as soon as you chop your cannabis harvest because the mycorrizae in the soil need a living root in the ground to attach to and keep the network alive - so shipping living soil would lose that bc theres no root, and so then whats the difference between their living soil and high quality organic soil except the price tag? With how marketing is these days its a solid question in my mind. I just don’t know until i look into it, but for me, true living soil is like the forest floor, undisturbed and constantly littered with rich decomposing greens and browns, and i hope to be able to keep a few containers of each size going, year round, with cover crops in the offseason to make some. For me, no till living soil is the aim for probably half my garden, for the other half i’m learning its probably unrealistic and i’ll just have very healthy high grade organic soil that i basically make myself through composting and adding organic feeds to what i have now - which is largely used FFOF and home depot organic garden soil bags. Both deprived of their nutritional content, but the FFOF is a great soil as far as physical makeup, perlite content, etc and the organic mulchy soil is the beginnings of the breakdown process and dense organic matter i hope to have in the future.
thanks for enduring the sativa ramble
