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.
Many Cannabis genetics naturally grow tall, with a similar appearance to pine trees, with one large bud on top and a smaller cola on the end of each branch. This growing method is successful outdoors because the sun moves across the sky throughout the day, allowing each branch (and bud) to receive light. However, when growing indoors, and to a lesser extent in greenhouses, this does not happen because the lights are stationary above the plants, never fully lighting the sides. Additionally, when growing indoors, it is important to keep the plant canopy as even as possible due to diminishing light intensity as the flowers get further from the light source (see: Inverse Square Law); this is not a problem with sun-grown cannabis as the sun is so far away that a few extra feet doesn’t make as much of a difference.
Many successful techniques can be used to propagate the Cannabis plant, each having it’s own benefits depending on the gardeners preference. Regular seeds, feminized seeds, clone multiplication and tissue culture multiplication are all used to start a crop with each having its place depending on available resources and gardener knowledge/skill.
As with all plants, cannabis plants benefit from occasional pruning. If done properly, it is possible to double yield through pruning alone. Pruning can lead to short, wide plants with lots of bud sites instead of tall, skinny plants with only a few large buds if desired by the gardener.
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).
