Root = life.
A lot can be written about the cannabis plant root, its morphology, and structure. It's safe to say that the root is the fundamental part of every single plant from which marijuana flowers will grow.
Fortunately, to properly care for roots, and thus ensure that marijuana seeds grow into healthy plants, we don't need to study its structure and operating principles in detail, but there are still some things worth knowing.
What about those humidifiers?
The dilemma of many American, Dutch, and even Canadian marijuana growers and seed collectors – Should I put a humidifier in my box or not?
A moment of thought...
Okay, everyone's putting a humidifier in, so I'll put one too.
And I'll tell you – read on...
The mechanism of water uptake and conduction is based primarily on transpiration. Evaporation of water from the surface of leaf parenchyma cells creates a state of tension in the water column in the vessels. Thanks to the cohesion of water molecules, this state is transferred along the root stem, which draws water from the soil.
Therefore, a negative hydrostatic pressure, caused by transpiration, prevails in the vessels, and the uninterrupted water column is maintained thanks to the cohesion (mutual attraction) of water molecules.
What does this mean?
This means that if your soil is rich in fertilizers from the start, even in small doses, when you provide high humidity in the box, you could accidentally burn or over-burn the roots of a young plant. This could set it up for trouble right from the start, without necessarily even realizing what's happening.
The plant won't absorb water from the ground, and therefore won't drink or eat fertilizers. It will instead marinate its roots in these fertilizers. It won't drink because it doesn't need to – the humidifier provides enough moisture to absorb what the leaves absorb. Very little evaporation will occur from the leaves, as the humidity inside the four walls of your cannabis home will still be high. The cycle is complete.
What it all grows on...
Soil consists of a solid phase, a liquid phase (soil solutions), and a gaseous phase (air contained in the soil). The plant draws its nourishment from the liquid phase. Soil water, constantly renewed by atmospheric precipitation – in the case of outdoor crops – occurs in the form of groundwater inaccessible to the plant, absorption water forming the hydration envelopes of soil colloids (swelling water), and capillary water – the actual water source for the plant.
Soil does not contain pure water, but solutions with a certain osmotic value. This value, along with the absorption and swelling forces of the soil, constitutes the soil's suction force, which the plant overcomes when absorbing water. Interesting fact: Normally, this force is on the order of one to several atmospheres, but in deserts and salty steppes, it can increase to even tens of atmospheres! This is the power of plants – they will suck up everything they can. Almost like a bad wife ;) :D
Suction and pressure.
It can be argued that the action of suction forces combined with active transport (that is, with a constant input of energy) creates what is known as root pressure, which is expressed by the constant rise of water in vessels, for example, in marijuana plants.
However, root pressure alone could not force water into the conductive pathways and sustain a column of water, sometimes of considerable height (e.g., tall trees such as oak and birch, but also large marijuana bushes measuring over 3 meters). Therefore, a second, and indeed the main, factor interacts with them: the suction effect, which occurs during transpiration. Due to a lack of humidity, air absorbs water vapor from leaf cells, causing their hydration to decrease.
In tall vessels, there is a risk of their walls collapsing (or simply breaking). This is counteracted by lignification and appropriate thickening of the vessel walls. Mother Nature has practically everything planned.
Soon, everything interesting about photosynthesis.
Warm Hemp Greetings.
