Calcium's role in Cannabis Physiology

Calcium's role in Cannabis Physiology

"Calcium is an extremely important plant nutrient due to its many functions, which includes membrane structural integrity, maintenance of homeostasis, segregation of genetic material during cell division, gene expression, energetics and enzyme activities. The full picture of calcium-mediated physiological processes has not been fully described here nor clarified in academic research; however, researchers do know that calcium is immobile in plants and that it is a constant requirement throughout all growth phases."

THE FACTS ABOUT DYNAMIC ACCUMULATORS. By: JOHN KITSTEINER

THE FACTS ABOUT DYNAMIC ACCUMULATORS. By:  JOHN KITSTEINER

Within the world of Permaculture we often find reference to plants known as Dynamic Accumulators. In brief, this is the idea that certain plants (often deep-rooted ones) will draw up nutrients from the lower layers of the soil, and these nutrients will be stored in the plants’ leaves. When the leaves fall in autumn and winter and are broken down, those stored nutrients are then incorporated into the upper layers of the soil where other plants will benefit from their deposition.

CHA Membership is now open to all interested researchers, educators, students, horticulturists and industry professionals.

Our membership is a premier package for individuals, professionals and businesses to take part in supporting and expanding their knowledge to develop the scientific understanding for cultivating the highest grade cannabis in the most sustainable fashion. Member funding goes to support the expansion of our database as well as conduct outreach to promote ecologically sound management for the cannabis industry. Our online resource center currently covers three broad categories of Integrated Pest Management, Integrated Nutrient Management & BioControls. Within those categories are a range of fields including but not limited to: pest and pathogen management, predatory insects, biochemical pesticides, microbial pesticides, organic chemical controls, soil chemistry, soil biology, soil physiology, nutrients, additives and a forum to discuss these methodologies and expound on other topics. The current content is heavily built around IPM and pest/pathogen management. (WE HAVE DESIGNED OUR PLATFORM AROUND ELIMINATING HARMFUL PESTICIDES AND TESTING CLEAN) The CHA forum is a private community that only members will have access to. This forum is run by admin with degrees in varying scientific fields. They are highly adept at networking with other peer scientists, growers and businesses to get your questions answered. If you can't find your answer in our database, ask an admin on the forum.

 

Plant growth-promoting (PGP) microbes

Plant growth-promoting (PGP) microbes

Plant growth-promoting (PGP) microbes are rhizosphere associated organisms that colonize the rhizosphere and rhizoplane and improve plant growth when artificially inoculated onto the seeds or into soil. PGP microbes may promote plant growth either by direct stimulation such as iron chelation, phosphate solubilization, nitrogen fixation and phytohormone production or by indirect stimulation such as suppression of plant pathogens and induction of resistance in host plants against pathogens.

Making the most of an efficient HVAC system for Greenhouses

Great article from Cannabis Business Times...

A greenhouse brings a grow closer to the elements, but the same sun that feeds the plants can also push the temperature far past the comfortable range for cannabis.

One main consideration is whether the greenhouse will be “open” or “closed,” says Nadia Sabeh, agricultural and mechanical engineer for consulting/engineering firm Guttmann & Blaevoet. An open greenhouse has some form of air flow from outside the structure, while a closed greenhouse is structured more like an indoor grow and mostly sealed. But even though an open greenhouse has more interaction with outside air, it doesn’t mean the cooling strategy is ... just to open a window, she says.

Depending on the location of the greenhouse, natural, passive ventilation is an option with ridge vents or open side walls, which can be manual or automated, says Sabeh....

Effect of Aerated Compost Tea on the Growth in Organic Cultivation

Effect of Aerated Compost Tea on the Growth in Organic Cultivation

Effect of Aerated Compost Tea on the Growth Promotion of Lettuce, Soybean, and Sweet Corn in Organic Cultivation
Journal of Plant Pathology 2015
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4564151/

Here we see that Compost Tea is well worth the effort.   Four types of compost were brewed and then the available nitrogen was determined, as well as the density of microbial communities, along with their affect on plant growth characteristics.  Across the board it was shown that aerating compost tea released more nutrients, increased microbial counts, and helped plants grow.  Way to go AACT.

HARVEST RAIN, HARVEST FLOWERS By: Lizandro Salazar

HARVEST RAIN, HARVEST FLOWERS   By: Lizandro Salazar

While regulators scratch their heads trying to figure out how to best
approach this topic, it’s clear that “business as usual” may turn into
“business unusual.” Many farmers groan as engineering fees, soil
tests, and permitting costs raise the price of going “legal”, but some
growers and professionals are nodding their heads in approval.

Shilajit - An Ayurvedic Powerhouse

Shilajit - An Ayurvedic Powerhouse

Often times I get the question, “How do I prevent my plants from getting sick?”. The
answer is simple, and that is through plant immunity. In short, there are two primary
factors that contribute to plant immunity:
1. Adequate Mineral Nutrition
2. Having that nutrition delivered in the form of microbial metabolites...

Product Spotlight - Grass Roots Grow Mats

Product Spotlight - Grass Roots Grow Mats

The CHA is happy to provide a spotlight on Grass Roots Grow Mats. They’re made from Hemp, which has been cultivated for fiber and food for over 10,000 years around the globe. The beautiful thing about Hemp is that it helps our planet and people throughout its entire life-cycle and then some! 

Grass Roots Grow Mats are now making hemp fiber grow plugs.  The CHA will be running experiments with them over the winter to determine the optimal parameters. Check out Grass Roots Grow Mats at: http://grassrootsgrowmats.com

One Bad Apple... Plant Growth Hormones and You. By: Luke A. Besmer

One Bad Apple... Plant Growth Hormones and You.  By: Luke A. Besmer

I am sure you’ve heard the old saying about how one bad apple spoils the bunch? Well it’s true, and of all things it’s due to a hormonal imbalance. Who’da thunk? So it turns out that in nature, the first ripe apple of the season drops to the ground and begins to decompose. During the decomposition process, the apple releases a gas called Ethylene. Ethylene is a Plant Growth Hormone (PGH) that triggers the nearby apples to fall to the ground and start the decomposition process. The sweet smell of all those decomposing apples attracts foraging animals who eat the apples and spread the seeds far and wide, often with a little fertilizer to boot (or conversely, to overwhelm scavengers so that some seeds are left undisturbed and able to safely germinate). Ethylene and other Plant Growth Hormones are vitally important to all aspects of plant growth and development, understanding them and their uses can improve any gardener’s yield.

Companion Planting for Cannabis. By: Royal Queen Seeds

If you are looking for a natural way to improve the conditions of your garden and even help with some pests, companion planting is an innovative yet not so new way to do just that. Companion planting is the strategic planting of fruits, vegetables or herbs alongside your cannabis plants in order to improve the natural ecosystem your plants are growing in - without turning to pesticides or additional supplementation. Companion planting is a natural and effective way of controlling mites and other pests, enhancing nutrient uptake and soil quality, as well as providing a habitat for beneficial creatures....
