- CULTIVATING KNOWLEDGE -
Achieving such a feat as reaching the optimal result with a specific cannabis strain doesn’t happen just by chance. Science and technologies are essential to bringing the best out of the hidden power of your plant. Active ingredients, such as mycorrhizal fungi, are definitely part of the equation. Let me explain why.
Seed germination and young plant production starts with the right growing medium or substrate. It is important to have a substrate with good physical characteristics, such as air porosity and water holding capacity, however chemical characteristics are equally important.
Mixing your own growing medium for organic crop culture can be quite a challenge. Learn more about the subject here.

A mixture of coarse and fine particles can be prejudicial for a substrate because the macropores will be filled by the fine particles, which reduces the air porosity of the growing medium.
Choosing the right substrate not only depends on the physical properties of the substrate, but also on the type of plants to be grown, the growing environment and the availability of the substrate.
When you see a picture of a harvested Canadian peat bog, it looks like any other field that is made up of mineral soil.
In Canada, peatlands cover 280 million acres (113.6 million hectares), or 13% of the land area of Canada.

The three main attributes associated with plant stretch from fertilizer are: fertilizer application rate, nitrogen forms and phosphorus.
Purchasing water soluble fertilizer for your crops is not simply based on what is on sale or selecting a “geranium fertilizer” for your geraniums; it is based mostly on the quality of your water source.
Vegetables and herbs fertilization requirements are similar to bedding plants early in their crop cycle. However, as vegetable and herb plants progress from vegetative growth into flowering and fruit production, fertility rates and ratios change for each crop.
Watering techniques have a major influence on crop quality and several crop production concerns.
During the crop cycle, some growers may have experienced pH drift that can affect the quality of their plants. Improper growing medium pH can lead to plant chlorosis (yellowing tissue), distortion of growth or leaf necrosis (brown, dead tissue).
If you have a pH meter, how often should it be used? How do you use a pH meter? Calibrating the meter, preparing the sample and taking the measurement takes some time, but knowing the pH of the growing medium can help avoid crop problems.
As the old saying goes, “an ounce of prevention is worth a pound of cure”. The cost of greenhouse sanitation is minimal in comparison to the costs associated with fixing problems, such as weeding and chemical pest control.
Growers may occasionally experience high pH problems with their growing media causing iron chlorosis in petunias and calibrachoa.
Over the last several years there has been an increasing trend for “Young Plant” producers to move from seed germination to cutting propagation. One of the more popular methods for cutting production is the use of the Ellepot machine. Discover more about this process in the following article.
