From an older Journal entry on the website:
I grow cannabis in soil, specifically cheap, easily obtainable, peat based potting soil. In the mid 90's when I first ventured into the online world of cannabis discussion in the Usenet group alt.pot.drugs.cultivation, two of the āveteransā of the group were the nyms pH and NPKaye. They were exceedingly knowledgeable cannabis developers, who were strong proponents of hydroponics. They were heavily into chemical fertilizers, measuring pH, etc.
I wonāt say they were condescending to those of us who utilized soil rather than water for a medium to develop roots in, but it was pretty close. Another of the knowledgeable veteran groups were militant, organic soil growers. They utilized soil but were adamant about using bone meal, blood meal, etc. _only_. Like the hydroponic group, they were also quite condescending, almost arrogant at times, about only using organic products and looked down on those of us who used regular, chemical fertilizers. So, Iāve got a bit of a chip on my shoulder for anyone who is adamant about there being one ābestā way to cultivate and develop cannabis, especially if itās hydroponic or organic. In all my years of growing cannabis, I have found there to be only one truth in regards to developing cannabis:
There is no _best_ way for developing superior cannabis because not only is everyoneās environment different but the genetics of the cannabis seed they use are variable as well.
So this is the system Iāve been using for utilizing soil as a medium for root development of the cannabis plant. If you explore a link to the BCGA website Iām going to give here in a bit, you will read about Vic High utilizing an ozone generator, to try and control gnats, that were attracted to all the bone meal, blood meal and chicken shit he used in his organic soil. I just never saw a reason to make things that complicated and difficult. I strive to keep things as simple as possible, so there are fewer variables for me to contend with.
I'm a dirt guy, and I could bore you to death with how I came up with the system that I use. One time long ago, I extensively experimented with organic fertilizers. I tried more bone meal, blood meal, chicken shit ( I never got into bat shit

) than you can ever imagine. See this section of Vic High's website to understand all the stuff I tried and yes I was an active participant in these discussions under a different nym, because I was so paranoid I didn't even trust the Canadians:
BCGA Super Soil
And as Chris Farley used to say... "For the love of God and all that's holy" don't mention the name of the guy, who is now dead, whose name is usually associated with super soil.
What I ended up doing was taking the best that I had learned from pH and NPKaye (who were hydroponic fanatics) on chemical fertilizers and decided to just use regular, cheap ass potting soil but with chemical fertilizers. I used to argue with Vic when he started using ozone generators around his grow, just to kill the fungus gnats, that were attracted by all of that organic material.
BOG took my method (that I strongly advocated for on adpc) and posted it on OG like it was his own idea. And never even mentioned my nym, because he knew I absolutely hated the flashy, blinky emoticons/smiley faces that were so popular on OG.
I digress... (zBear but absolutely fucking love that).
Here's the system I use, with pictures. I start with this, which is old soil with fan leaves and other non-bud material from the winter grow that I recycle:

Mix it in with a couple of bags of this, which is composted cow shit:

Add in a couple of bags of this:

Which is cheap ass Lowe's potting soil but it used to be Miracle-Gro before this inflation bullshit. Whatever the fuck was on sale and cheap is what I was interested in. There's a nym on IC, who I can't remember... imagine that... who frequently states that he grows in Miracle Grow just to piss people off, we are kindred spirits!!!!
This is the next thing I do, in extremis:

Massive, 10 to 15 minute streams of pure Blue Ridge mountain spring water, spend about 15 to 20 minutes mixing it all up with a shovel and a hoe... and my wife just now said don't call me a ho.

And we're almost done.
This is not a product placement and I put it in another thread, but here is all I need after I prepare the soil:

Didn't take a picture of the two handfuls of dolomitic lime and couple of pinches of Epsom salts that I throw in, just for old time sake. Many years ago, I was broke as a fuck and had to reuse soil... a bunch. After many grows, things got funky as shit, discolored leaves, stunted growth, etc. I used a little bit of Epsom salt and some lime I had left over from the vegetable garden. Things got back to normal. Don't know If it was a calcium or magnesium deficiency but it cured the problem."
So that's why I use soil and chemical fertilizers... it just works well for me, in the environment I develop cannabis in and at this point I just don't see a compelling reason to not only change but even to experiment with hydroponics and organics.
Here is how roots develop in this soil:
