This comment is sort of addressing the 7 or so posts directly above.....
We're trying to produce flowers that:
1. do fantastic things to our consciousness
2. taste great
3. are perfectly healthy to consume in every way
Being a chemist (I'm not) or someone with advanced training in soil agronomy, ornamental horticulture, crop science and soil science is all well and good, and we need people like this on our team.....
But what we really do is more like being a chef than a chemist. A scientist might tell you why something tastes so good, but they could never tell you on paper HOW to make something taste good. That's what a chef does. A chef is a practical chemist.....while a chemist might not even be able to cook.
So, what I'm trying to say is that growing great weed is like being a great chef, not like being a pHD in soil science. We want those people on our team, but we need not have the level of knowledge they have....we do need them to find out certain things for us....but in the end it's personal creativity coupled with hard science that wins the day.
For example: A chemist understands how heat de-natures protein by breaking polypeptide bonds.....In contrast, a chef knows how to make fantastic omelets. The chemistry is the same....but one applies it with style and panache, while the other merely defines it.
So, what am I trying to say?
Learn about the soil and the microbes and how they work in principle. Upon learning the basic principles, start acting like a chef....mixing this, trying that....all the while sticking to principles that are proven.
Now, let's talk about layers of soil:
1. Everything leaches out of the pot at varying rates.
2. roots grow down, out, in and around.....
So, should these "layers" be oriented vertically for roots to grow out, or should they be horizontally stacked like plates for the roots to grow down?
How can we stop one layer from mixing with the layer below?
My scientific side knows that we can have 2 distinct layers.....a top layer and a bottom layer and the top layer always mixes with the bottom, but rarely the other way around, unless you bottom feed and rely on wicking action, but even that will not take what's on the bottom layer and switch it to the top.
So, if you want layers, you get to choose 2. That's the chemist/soil scientist talking and he's right.
The chef/grower understands all of the above and experiments with little things here and there in order to:
......produce flowers that:
1. do fantastic things to our consciousness
2. taste great
3. are perfectly healthy to consume in every way
Violate the science and you have problems....period. But the science of growing has many ingredients to choose from....and it's the chef/grower's job to mix, match, tweak and try different things that scientifically sound in order to get the best results.
Weed growers are great chefs.....but many are ignorant of science. Egghead academics are often great scientists.....but lack the panache and style to do special things with their produce.
So.....I employ a lab to keep me on the straight and narrow with regard to science.....but when it comes to growing, I function as a chef, not a scientist.
Dang....I wrote this with 4 interruptions, I hope it makes sense.
