Cannabis root system

The Roots Are the Most Important Part of Your Cannabis Plant
What is a ‘vital organ’? It’s an organ that’s absolutely necessary in order for life to continue for the organism it belongs to. To a cannabis plant, the roots are its vital ‘organ’.

What You Can Do: If you’re using properly amended soil, you’re most likely good to go. Lucky! Everyone else should make a point to check the pH of their root zone often to ensure proper nutrient uptake. Bad pH equates to bad nutrient uptake which equates to damaged-looking leaves and plants.
Rootbound (Not Enough Space for Roots to Grow)
The size of a plant is determined in part by the amount of space the roots have to grow. Once the roots run out of space – known as being ‘rootbound’ – the growth of the plant will grind to a halt unless conditions change. Although this won’t necessarily degrade the health of the roots directly, the rest of the plant will directly suffer in the form of stunted growth.

The leaves of a cannabis plant can also take in nutrients; growers can do this through a method called ‘foliar feeding’, where a nutrient solution is applied directly to the leaves.
Overwatering or Underwatering (Too Much or Not Enough Water)
Overwatering is the term used to describe when there isn’t enough oxygen at the roots of a plant. This pretty much only happens when there is an excess of water in the medium (not counting DWC), so we call it overwatering. That being said, plants grown in DWC can also show signs of being overwatered if there isn’t enough oxygen in the reservoir water.
Today we’re going to show you how to protect your plant’s lovely roots, and your plant will pay you back in sticky home-grown bud!
Underwatering is exactly what it sounds like. If a plant isn’t getting enough water it starts to suffer in a way that looks just like overwatering.
Root Rot (Pythium)
Although Root Rot is a larger problem for hydroponic growers (such as those doing DWC), it can affect any grow where the roots are sitting in stagnating water. That includes the saucers some growers use underneath those old-style pots. This is far less likely to happen in outdoor grows in soil since water can go further underground.

In turn, during harvest, we will notice that the plants fed silicon will have a much smaller internode distance compared to other specimens whose nutritional diet didn’t contain silicon. It should be noted that this material also provides more hardiness and strength against adverse weather conditions such as rain or strong winds.

The roots perform vital functions for the plant

This is due to a prolonged excess of moisture in the substrate. During these periods of high humidity, the roots run out of oxygen, changing from an immaculate white hue to a darker colour that slowly turns to brown.
For this reason, it’s crucial to respect the proper wetness and dryness cycles during the entire growth period in order to get a powerful and vigorous root system capable of absorbing large amounts of nutrients, eventually resulting in a large plant with amazing bud production.
Root rot caused by overwatering
Flushing your plants is a simple process that it’s vital in order to harvest high-quality buds free from any nutrient excesses that could alter its taste and smell.
One of the main roles of the roots is maintaining the plant in an upright position and firmly anchored to the ground. If the root system is poorly developed, the plant will need some type of support to stop it from falling over, especially during the flowering phase, when the branches have to hold more weight due to bud formation.

The roots form the foundations of the plants, given that over its life, the plant is gradually built onto them. In addition, they also perform some vital functions, as we will explain below.

A successful harvest depends to a great extent on the condition of your plants’ roots. In this article you’ll see the most commonly found problems wit
