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.

The Future of Pesticides...Pyrolysis Studies and Separate Classifications for Flowers, Concentrates and Edibles

The Future of Pesticides...Pyrolysis Studies and Separate Classifications for Flowers, Concentrates and Edibles

Accounting to the obscurity of past regulations, pesticide testing on cannabis is only now seeing the light of day.  The absence of official federal government rulings has left state regulators scrambling to standardize, monitor and enforce these guidelines on their own.

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.

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.

Caterpillar Management -  Identification and IPM Practices

Fall is here and so are the caterpillars, at least in Northern California. We have documented numerous instances of caterpillar damage and can officially say there has been a decent hatch this year. ...
