Growing up and normalizing your nutrients

The first ten years have passed since Washington and Colorado legalized adult cannabis in the United States – and Canada may be close to four years leading the way in national legitimacy. For commercial farmers, today’s landscape is very different from the past. The current commercial cannabis diet is very different from the beginning.

Approach to developing systems

Growing areas of highly controlled areas and technological advances are growing, and growers want a more inclusive system-based development approach. Horticulture expert Shaye Donald and agronomist Jean-Pierre Fortin, members of the Hawthorne Gardening Company Technical Service team, work directly with growers as part of a comprehensive approach to developing practices and product use.

In the past, farmers focused on nutrition, but Donald noted that attitudes were changing. Although nutrition is important, it is being viewed as a whole. Many growers focus on integrated development, with integrated nutrition, irrigation, fertility and other aspects of growth.

“Plants, like all living things, are complex, so their environment is not just one piece. It’s a system where everyone is connected and connected, ”said Donald. At Hawthorne, the concept behind this trend is home to the Hawthorne 360 ​​initiative. He added: “It’s all about knowing that this is a system, so we have to take the approach of the systems.”

Nutrition-based crop leader

Donald shares that crop leader: Managing points or inputs to stimulate certain plant responses in the growth process is another trend.

“It is human nature to change the crop leader to get the response we want,” he explains.

When Growers Recognize the Importance of Changes During the Crop – From light conditions and fertilizer levels to irrigation and environmental conditions such as humidity and temperature, growers are more likely to focus on adjusting their points.

“In terms of nutrients, there are many different signals that we send to the crop, especially macro-nutrients,” says Donald. By changing the nutrient ratio – especially nitrogen, phosphorus, potassium, calcium and magnesium – growers can respond to plants at different stages of development. A simple example is to increase nitrogen at the plant level to encourage and support leaf and stem growth.

“Then when you get to the flower, you want to give more nutrients to the flower structures and then to the secondary metabolism,” Donald said. Hawthorne’s study focused on how to better feed crops to find the answers that growers most desperately needed.

Irrigation automation and management

The need for irrigation has long been assessed. But as the business moves towards more automated water and nutrients supply, this is changing – for better crop management results.

“If the trend is smart, people are moving to automation,” Donald says. “Many of these [crop steering] Techniques are highly dependent on automated equipment. He added that it is very difficult to water crops safely by hand.

According to Fortin and Donald, many growers still supply water – especially in new markets. But automated dropping irrigation, a key part of the Hawthorne 360 ​​approach, is on the rise. Combined with automated fertilization and simpler, more efficient nutrients, growers can easily and efficiently change their diets to manage crops and save money.

Automation can go from simple to complex. The most basic level, according to Fortin, is just a timer to trigger irrigation events.

“If we go through the automation, we may have soil moisture sensors that detect moisture content, and some irrigation sites will be set up in that control software,” he explains.

Fortin emphasizes that many of the problems in commercial plants are related to lack of consistency. Automatic irrigation and a better, thinner fertilizer program can help. “It’s similar in water, but water is a carrier of the diet,” he says. “So it’s similar to a crop diet – and that increases.”

Small growing media volume

Nutrition-based crop management and automated drip irrigation link movement to significantly reduced pot sizes or to small root zones in commercial cannabis. Automation allows frequent watering, which allows growers to reduce the amount of clay and increase the capacity of nutrient-based crop management techniques.

Fortin explains that there are two main ways of crop management: “The first is a very small container for a large plant. Obviously you can’t meet the needs of the day with just one water, so we have to pay for watering at various events. The rock wool cube is an example of a small media growing to hold enough water to meet the needs of the day.

Once automation and small root zones are played, the next step is nutrition. Once a day, instead of watering the plant with all the nutrients it needs, it can provide nutrients throughout the day, just as a plant needs. Fortin explains that in a small root zone water carries nutrients closer to the root, making it more efficient to absorb.

Growing media allows for greater control, allowing growers to play with what is commonly called dry background — especially during irrigation events or the amount of dryness allowed before the first irrigation event in the morning.

“I think things are moving in that direction,” said Donald. “General Communication If you have a dry root zone – if the plant detects a drought-like stress – then it will start sending signals that could affect the lower basin. For example, increase flowering.

“I like to think I’m always learning, and I think the best growers are always learning,” Donald added.

Acceptance of systematic approach is part of its development. By treating overall growth as a system, all aspects interrelated and working together, you can achieve these trends by making each business cannabis diet more effective, more efficient and more profitable.
