You know my mom paid a lot of money for me to learn that many years ago and who knew she coulda saved some money and just had me log into a cannabis forum for me to pay attention to itAlright so we touched on water and VPD.. Before we get much further I’m gonna breakdown some basic chemistry information so we can discuss nutrients without going over too many peoples heads.. The whole idea of these posts is to make plants a little more accessible so folks can think for themselves beyond following directions or internet tips on growing.
Plants are autotrophic, meaning they can produce their own food using light, water, carbon dioxide, or other chemicals. They use 17 elements to create everything they need for life. These are known as essential elements. There may be more that have an effect, but plants do not require them to survive and reproduce.
Each nutrient is an element, a substance composed of identical atoms. Atoms are the smallest unit of an element. An atom has positively charged protons in its nucleus, which is surrounded by a cloud of negatively charged electrons.
When atoms of the same or different elements share electrons, a chemical bond is formed. Nutrients form three types of bonds: covalent, ionic, and hydrogen bonds. These affect the qualities and availability of the various nutrients. Plants take in the nutrients in order to build the four types of molecules that are necessary for life: carbohydrates, proteins, lipids, and nucleic acids.
Molecules are the smallest unit of a compound. They result from atoms bonding together. Plants are simply the combination of those four groups of molecules. In fact, so is all life. The only difference between us the cultivators and a bacterium is the way carbohydrate, lipid, protein, and nucleic acid molecules are put together.
I know that can be a little intense, but it will make more sense as we discuss in further detail some of these things. The bonds will be explained as we get to them, however I think it’s important for people to at least hear these words so it can make describing the processes a little bit easier.

I love the science class it’s literally unlocking so much more understanding of the plant and what my large actions above the soil do to them on a molecular level!
Freaking mind blowing
I can’t put into words how hard I just laughed. This was the FIRST thing I read this morning after my eyes were open for all but a minute!My mother tried as well, and all was good until I turned 13 and discovered Cannabis to be fair though, it was at that point I realized I’d been lied to by a lot of people. I smoked a joint and laughed my butt off and had an amazing time.. I didn’t instantly end up on a crack House floor giving my body away for hits of dope so I became very suspicious about all the things the adults had told me up to that point lol.
Yea I fell for the whole “UnCle SaM WIlL TeaCh YOU thInGs nO UnI eVEr COuld” bit and the rest is history.What I did realize though was, I can learn easily if I’m interested and engaged, and because I insisted on taking the hard road with the working class instead of the university road with the white collar kids, I learned how to speak and explain things in a way the masses can understand. Look at me now mom!
Yes If I have to second guess myself I step back and go read more. Whatever I do I should be doing it knowing the cause effect and do it as you said with confidence.On a more serious note though.. I know exactly what you mean.. It also really helps give you that confidence and ability to look at your plants and understand even the smallest of moves you perform can have seriously huge impacts down below. You’ll hear me harp on confidence almost as much as balance. Confidence separates good from great, and REALLY separates bad from good.
I just learned something so incredible I had to pullover in the middle of my route and share it. Specific bacteria work better on specific plants which determines things like hardiness, disease, efficiency, etc. This goes even further in Cannabis where specific strains have specific bacteria that work better.
These bacteria (I’m gonna break down in way more detail all of this including rhizophagy) are transferred from plant to plant through the seeds. These seeds hold the bacteria until the seed germinates. The moment the seed germinates these bacteria explode out of the seed and into the environment around them to get the ball rolling in terms of growth, health, etc.
This means that when you germinate in a paper towel or sterile environment, those bacteria that the plant has been refining for generations escape out into the paper towel or the sterile environment and are lost.
These bacteria are responsible for so many things such as resilience to PM, the ability to build root hairs, etc. just think about the implication of losing them upon germination.
I will be going back to planting directly into the soil.. I’ll still wet the seeds and roll them in myco but no longer will I germinate them in liquid unless I can pour all of that liquid into the soil and even then only one seed per vessel.
That's interesting about the seeds and built in microbes. Something I had never considered.
Ok my bad.. I got my wires crossed on this one.. What I have is quite a few studies and reports that explain all the known factors affecting seed viability. The major factors affecting viability in storage are related to what I posted. Temperature, RH, light, air.
Those are the major factors that affect the storage viability, however provenance and/or “pre-harvest” also majorly affect seed viability, aka seed vigor. Seeds are embryonic plants, with a nutrition source inside. In flowering plants, the nutritional materials are composed of oils, fats, starches, and many other compounds including sugars.
During pre harvest a variety of factors such as the environment (temperature), stress, nutrition, drought, etc all have an effect on the quality of the seed. “All parts of the seed deteriorate with time, the damage from which can be sustained by the chemical constituents of seeds and the way these compounds interact to form biological structures. Integrity of DNA, proteins, and membranes is especially important for maintaining seed viability”
“Environmental stresses, including deficiency of minerals (including nitrogen, potassium, and calcium), water and temperature extremes during seed development and prior to physiological maturity can also reduce the longevity of seeds.”
So because seeds are made of genetic materials that are heavily influenced by environmental stresses, the plants natural processes, and also include strain specific rhizophagy bacteria refined over the strains life time that are stored in the seed itself, and upon germination escape into the medium around them, it gives us a small window to theorize. (This strain specific rhizophagy, and the natural nutritional processes I believe is going to be where the influences are happening)
In the 70s and 80s “wild” cannabis seeds it was written, were found to last far, far longer than domesticated plants. There’s records that show these wild canna seeds lasting as long as 1300 years in some instances.
Modern breeders see nothing even close to that. What they have seen though is that plants they have grown synthetically, and those that have been forced to seed (feminized), quickly break down, become unstable and lose viability.. Within 2 years in some instances they notice a marked loss in quality. In a lot of instances, certain strains can no longer be grown outdoors without “herming”.
Whereas organic seed breeders are seeing viability for as long as 10 years without intentional proper storage in some instances, normally more around 5 without protection.
Due to 70+ years of prohibition and at least 50+ years of research prohibition, a lot of what we have in terms of data comes from breeders. This is quickly changing due to a variety of federal initiatives and cannabis being legal in multiple states, but it still leaves us with a dearth of hard scientific data.
We have a lot of knowledge (which is quickly exploding due to the threat of extinction to at least 8% of our current plant life) on the influences on seed viability and vigor. However, seeds can vary wildly from phenotype to phenotype never mind cultivar to cultivar. I’ve posted a bit of it up top and will link the resources for others to see.
So with all of this, plus what we now know of strain specific bacteria that is seed bound upon reproduction, it is believed that the current methods of synthetic growing weaken the plants natural systems. A lot of the innate processes the plant performs are being replaced by growers using sterile mediums and synthetically chelated nutrients. These processes need to be developed within the plant and if we’re performing them for the plant the plant has no reason to perform them itself. Thus leading to a weakening in the plants ability to effectively reproduce.
Not only that, these bacteria that are bound within the seed have been refined over generations. When growers germinate into a paper towel or sterile media, that evolved bacteria is lost forever. These bacteria carry everything from resistance to PM, to the ability to generate root hairs. Losing them upon germination has massive implications for the stability of the plant, and it loses years of evolution. This is a relatively recent finding (first observed in 2018). I’ve been digging into it and am quite gobsmacked at what they’re observing.
With all of that being said, we’re left with what breeders have told us, what science is seeing, what growers have seen when using synthetic versus organic methods, and a few major inferences and implications. The breeders obviously have reasons to be less than honest, however if you take the average of each of their claims you’re left with similar numbers to what I posted. At the end of the day we’re left to rely upon the integrity of our fellow growers for a lot of this. I’ve sourced my time frames only from reputable breeders and their observations and statements.
Seeds seem so innocuous but are so wildly interesting I’m excited to see where we go from here. With funding amping up, and money to be found, you can bet us Canna growers will be getting a lot more data in the coming years. With advances in microscopy that allow us to see at the atomic level we hopefully will start unleashing some truly strong evidence. There’s still plenty of room for folks to get in and make their mark.
In the future I’ll make sure I add a disclaimer when referring to longevity

Furthering my realization I was lied to even more that I thought.
I'm like that, as well. I found a notebook I can write stuff down in, and have a record of it. Works for me.I will either need to go back and listen multiple times or just read more about it.
Similar, here. And have grown more so, since the Democrats wage war against Republicans, costing taxpayers all that money, and not getting anything meaningful done. Look at the way they're (states and federal) rolling out cannabis legislation? Has to be a huge money game! Well, there it is! Time for be to go back lurking, lol. Happy Smokin'We got out, and we went under the radar completely.
Highya Kefka,
Similar thinking patterns. Surprising to me.

Aren't chloroplasts the structures which perform photosynthesis?Also learned that “light bleaching” is due to the ratio of red light in your LED. This is fascinating as well. Red light is efficient and plants do not need to make protective chloroplasts to protect against it. This is why the white color appears.. The plants do not need the protection because of the efficiency of the light therefore no chlorophyll. This should technically mean no impact on quality but I doubt it’s as simple as that.
