Hello my friends, As someone privileged to explore an array of new products within the cannabis field, I've come across innovations that truly disrupt the status quo every so often.  One aspect that has long begged for evolution is the curing process. The traditional 'burping' approach, though effective to an extent, leaves much to be desired in terms of efficiency, safety, and ease of use. Enter TerpLoc, a paradigm-shifting solution that transcends the limitations of conventional curing. This innovative product has caught my attention for its elegant and incredibly effective approach to ..read more

Caterpillars - a late-summer pest in your Cannabis Garden

The photo above: You might not see the caterpillar because it is already burrowed deep into the flower, but you can spot its feces. If you have caterpillars botrytis is not far behind. It grows on the feces and the areas where the caterpillar damaged the plant. It pays to be vigilant! Photo by Christian Petke In July, my newsletters discussed battling plant enemies like bugs and mold. But there’s another cannabis enemy that may affect your garden later in the season: caterpillars. Caterpillars are the larval stage of butterflies and moths. Caterpillars are often the same color as leaves ..read more

How can you help your Cannabis plants to thrive in heat waves?

Signs of heat stress - The Photo above: By Dutch Passion Seed Company Cannabis plants are hardy and survive outdoors in a wide range of temperatures. As the temperature rises past 85°F (30°C), photosynthesis slows until it stops between 90–95°F (32–35°C). At this point, plants go into preservation mode; photosynthesis stops as the plants spend energy acquiring water through the roots and transpiring it through the stomata to keep cool.  For short periods, most cultivars withstand weather, up to 120°F (49°C), as long as they have adequate supplies of water and a large enough root system ..read more

Why C02 Matters in Your Cannabis Grow: And How to Generate More of It
Ed Rosenthal Blog

7M ago
Medium Size Indoor Garden / Photo by David Downs “Before you add another light, add C02.” — Ed Rosenthal The importance of carbon dioxide cannot be understated in the cultivation process. Having robust C02 levels ensures optimal plant health and maximum yield. Plants create sugars using the process of photosynthesis which is powered by light. The light is used to separate water’s two elements oxygen and hydrogen. The oxygen floats into the air. The Oxygen is combined with CO2 to create sugar, which is used as food to power metabolism and to grow. As noted in the Cannabis Grower’s Handbook: Ca ..read more

Drying Cannabis Plants. Cannabis cultivators of all types need to control every step of the process from seed to smoke. Nurturing the life cycle of the plant is only the beginning. After putting so much care into the cultivation process, it’s critical to ensure buds are dried, cured, and stored in a clean, stable environment that preserves terpenes, potency, and quality. Placing fresh cut Cannabis flower on hangers. Advances in cultivation have seen the dry and cure process evolve significantly in recent years. Long gone are the days when towering stalks were simply hang-dried next to a fan ..read more

Hi friends, today’s guest blogger is James Driskill from happytreemicrobes . He is an expert in soil health and he will explain to us why adding microbes to your soil is a real game changer! Thank you Ed for giving me the opportunity to talk about this. Hey gardeners, today I want to shine some light on our microscopic buddies that look after our plants, and us too. Many of us have heard that the root zone of a plant is analogous to our own gut microbiome. If our gut flora is disturbed or destroyed by things like antibiotics, disease, or an unhealthy diet, we suffer. It seems like more and mor ..read more

Indoor lighting – it’s a whole new world by Ed Rosenthal from the Cannabis Grower's Handbook
Ed Rosenthal Blog

Light Quality The quality of light is its color, or spectrum. Light spectrum is useful for directing the plant’s growth habits, as well as contributing to healthy photosynthesis. Comparing this to a car, if light intensity is the gas pedal to increase speed of photosynthesis, light quality would be the steering wheel. Using different colors of light allows growers to affect the plant in terms of yield, flavor, color, growth, flowering, and even the severity of pests and diseases (Davis and Burns 2016).   Light color, as described in this text, is part of the electromagnetic spectrum that ..read more
