Ecological Concerns Build Over Rockwool Manufacturing and Health

For many decades now, Rockwool has been the cornerstone of the clone and hydroponic industry. Providing a sterile media with excellent oxygen retention, even while fully saturated, rockwool has always been a go to for many. But in light of the changing industry dynamics and ecological calamity of corporate pollution, it is now important to look closer at its manufacturing processes and waste stream and make hard decisions about changing our ways.

Lead Contamination in Garden Hoses Poses Risk for Cannabis Farmers

With heavy metal concerns being addressed in Phase 3 testing in California now, it’s important to consider all source points of contamination. And one concern is coming directly from the source that was supposed to provide life, the water. And as it turns out, many traditional garden hoses have become source points for pollution.

Companion Planting for Cannabis

Examining the Management of Ecological Habitats for Beneficial Insects

Background

With a growing concern for eliminating pesticide residue in cannabis, farmers are learning to incorporate beneficial insects into their Integrated Pest Management (IPM) methodologies. Along with this IPM comes the potential to integrate the habitats for these insects, which ultimately decreases a dependency of purchasing them. Regenerative and biodynamic management are now amalgamating with IPM, helping us develop new insight for the complexity of running these systems. This article will attempt to encompass the broad concepts of companion planting beneficial insects and discuss the caveats of landscape management for these integrated ecosystems.

Malaysia’s warm temperatures and wet climate create almost greenhouse like conditions that can be great for growing plants, but also great for culturing plant-disease causing fungi. Researchers from Malaysia’s University of Technology wanted to determine what affect compost tea had on the growth of the leaf spot causing Grammothele lineata. The test plant was the Asian herb Melicope ptelefolia which is known for it’s edible and medicinal qualities.

Hempot™ Hemp Fiber Propagation Pots

The Hempot™ is a transplantable propagation pot made completely out of hemp fiber. It’s materials and stitching are designed to be very sturdy during above ground usage but completely biodegradable upon transplanting. This pot is designed to be planted directly into the ground during transplanting. The unique woven fiber allows the plants roots to grow directly through the sidewalls upon contact. It’s adsorbent fiber will wick and store water, allowing the plants roots to not dry out too quickly upon transplanting, thus reducing shock. The fiber quickly breaks down to build soil organic matter. It has been designed and tested in Humboldt County, CA by iEarth, LLC.

Hemp is Legalized!!!

After 80 years of federal prohibition, the hemp plant has finally been “re-legalized” by President Trump signing this historic farm bill. This is a momentous shift for the cannabis industry in general and should help to begin rapidly deconstructing the stigma of cannabis in the eyes of the American public. The history of hemp has a sordid past, wrought with insider conflict of corporate barons, all jockeying to retain positions of their dominant industries. Thanks to the hard work Jack Herer, much of this corporate cronysim was disclosed in his book, The Emperor Wears No Clothes. But today we will not dive into the dark side of hemp prohibition, but instead remind you of hemp’s importance in the founding years of the United States of America and also include worthwhile elements noted about the farm bill.
