October marks one year of Growing with Surna, the Surna blog. To celebrate, we’d like to take a look back at the most popular posts to date.
As discussed previously, it is important to make sure the correct measurement is being considered when choosing a bulb or reflector. Lumens measure brightness as seen by humans, but PPFD measures light density as seen by plants.
When growing cannabis, it is important to closely monitor everything that is added to the plant, this includes the type of water used, how much of each nutrient is added and anything else you may introduce directly to the plant. In this post, we will focus on the importance of closely monitoring the nutrients added to a plant, but the same theory can be applied to anything else – remember, if not purified, water contains minerals and nutrients that may not be accounted for in your nutrient schedule and that could have drastic impacts.
Each month, we publish a newsletter discussing a trending topic within the cannabis industry and how it shapes Surna’s philosophy. To be one of the first to receive this information, be sure to sign up for our email list at the bottom of the page.
The Veg Room is where baby plants from the Nursery become teen plants and are grown to maturity before being moved into the Flower Room. The majority of the cannabis plants leafy growth and elongation will occur in Veg, however stretching will continue for 2-3 weeks into a 12/12 photoperiod (Flower) where they’ll grow another 30% in size before shifting energy to flower mass production.
Lighting is a huge part of commercial cannabis cultivation. Some estimates assign up to 33% of all energy used in an indoor grow to lighting. Additionally, the number of lights you plan to use will determine the size of your grow (commercial grows are often referred to by the number of lights they include, rather than by square footage).
In cannabis cultivation, as in life, there are two types of stress – good and bad. Good stress causes the cannabis plant to work harder to achieve a desirable goal (larger buds anyone?); whereas, bad stress is counterproductive to growth and could ultimately kill the plant. As such, when growing cannabis in a commercial setting, it is important to maximize the use of good stress and minimize the introduction of bad stress.
