CO2 ENRICHMENT - A critical tool for maximizing yields … and it’s not just for warehouses

Enriching the air around your plants with CO2 supercharges the photosynthetic process, creating healthier plants and, ultimately, bigger yields. Gaining sufficient carbon from CO2 is important even at the earliest stages of plant development, when the plant prioritizes root development. Like compound interest, these early “investments” in plant structure support the creation of additional biomass as the plant matures. The best results from CO2 enrichment are realized when it’s applied to both the vegetative and flowering stages.

Yield improvements from CO2 enrichment derive from more, larger, and denser buds and can exceed 30-40% … commonly generating 25-30 pounds of additional finished product per 1,000 square feet per harvest. As Ed Rosenthal likes to say, plants evolved when there were greater concentrations of CO2 in the atmosphere and they “know” how to use more of it.

The Best Way To Germinate Seeds

When it comes to germinating cannabis seeds there are many different ways to get those tiny jewel boxes of prized genetics to pop. In response to my scientific investigations exploring different methodologies for germinating seeds, Marijuana Seed Breeders conducted a survey of experts and home growers to ask about their preferred method of germination. I wanted to share the results of this survey as well as some of my own tips for spouting your seeds. Let’s give our plants the best chances possible to grow into their full potential by starting them off right.

This year, job seekers can expect to see hiring at all levels of the supply chain.

The History of Ice Water Hash

As with so many things related to cannabis, ice water hash washing has its roots in Amsterdam. As the legend goes, a man named Sadu Sam determined that the resinous trichomes on the cannabis plant are packed with oil-based compounds. Trichomes are the "mitochondria" of the cannabis plant—the part full of precious cannabinoids. The trichomes' oil results in the compounds sinking in water. Meanwhile, the rest of the plant floats to the top. This is the basis of hash washing, or "Sadu Sam's Secret."

Don't leave your profits in the dust!

Collecting kief is a great way to get the most out of your harvest. Whenever I have a bag of trim I make sure to not let the trichomes go to waste by using a simple dry sift method utilizing a mesh screen and a kief collector that’s small enough to fit on my desk while I write. Trichomes and crystals cover both the bud and the sugar leaves on the cannabis plant and should not be squandered!

Building a Wick System: An Easy Way to Grow

This excerpt from my new book “Ask Ed: Marijuana Success” hones in on one of my favorite ways to grow cannabis at home with a wick system.

The wick container system is an easy way to garden because it’s self-watering and removes the uncertainty of when to water. It requires far less care than hand watering, and it’s simple, fast to assemble, and inexpensive to set up. The wick system is based on capillary action. One example of this is a tissue drawing up water from a puddle. The system we set up works on the same principle. Instead of tissue, we use braided nylon rope.
