Advances in Grow Light Technology: LED vs HPS  

Stefanos Gialamas
Not all artificial lighting is created equal.  When it comes to cannabis cultivation, it has recently been discovered that exposing plants to different spectrums of light causes noticeable changes in plant structure, or morphology, and in cannabinoid and THC content. In Greece and elsewhere in Europe, medical cannabis can only...

Floor Heating for Greenhouses

Stefanos Gialamas
Greenhouses allow us to cultivate in climates that are variable in temperature, protect from the wind and provide a cleaner space free of pathogens and predatory insects. While the insulation of the greenhouse covering will raise the temperature in even mild to chilly weather, some windy and cold over cast...

Selecting Cannabis Mothers for Cloning

Stefanos Gialamas
Pharmaceutical cannabis requires uniformity of product on a mass scale.  Because there is so much variation between cultivars, this means producers must grow large amounts of genetically consistent plants.   The best way to ensure this is through the process of “cloning”: cutting branches from a “Mother” plant, and inducing them...

Air Cooling Systems for Greenhouses

Stefanos Gialamas
Greenhouses capture sunlight energy.  Radiation trapped in the greenhouse will release heat as photons interact with matter and lose energy. While abundant sunshine promotes vigorous and rapid growth, the extreme heat makes utilizing cooling systems mandatory during the hot summer months, especially in Mediterranean climates such as Greece.  Different cooling...

Some Failed Fantasies of Prohibition

Stefanos Gialamas
Despite its seeming omnipotence, the web of twentieth century global cannabis prohibition contained many holes from its inception. As soon as one hole was closed, new ones opened up. This difficulty was largely due to the long historical relationship which human beings have had with the cannabis plant. Many societies...

Composting for Cannabis

Stefanos Gialamas
Compost vs. Commercial Fertilizer   Composting is the science of building soil dense with microbial life which supports vigorous and healthy plant growth through bio-chemical reactions and other life processes.  This complex and symbiotic plant-microbe relationship is illuminated in our first issue’s article, “Living Soils”.   In essence, composting refers...

Energy Efficiency

Stefanos Gialamas
Today’s Indoor cultivation facilities are energy intensive as they must provide every input for the plants: Light, Temperature and Humidity Control, Nutrients, and Air Flow. Indoor growing allows you to be very precise in providing these inputs at the cost of a very high energy budget. In general, indoor growing...
