This is why indoor growers need to make a deliberate effort to not only create long, bright days but also emulate dark cycles for cannabis to grow large full buds. Nighttime provides darkness, keeping cannabis on somewhat of a natural clock. When you are ready for your cannabis plants to flower, a 12-hours of light and 12-hours of darkness schedule is standard. (Note that most indoor growers vegetate their plants 4 – 8 weeks.) The Flowering Stage of Cannabis In fact, indoor growers commonly use an 18/6 light to dark ratio to encourage faster growth. The Vegetative Stage of CannabisĬannabis in the vegetative stage (when it is growing at a rapid pace) needs at least 13 hours of light per day. Below are the we discuss how much darkness is needed at each stage of growth. A light-deprivation system helps to control exactly how much light is exposed and reap many benefits. Light deprivation is ideal for producing high-quality crops. That timing is critical to maximizing your yield. If you’re new to the strain (or growing), talk to old hands about when to end the vegetative phase and trigger your plants’ flowering phase. Depending upon the strain you’re working with as well as your environmental demands, your light-to-dark ratio will vary a bit.
The result is seeds, which allow the plant to produce the next generation.Īs a cultivated plant, cannabis still responds to light changes. In nature, male cannabis sacs release pollen to pollinate female plants in blossom. That means when the days grow shorter, the plant’s life cycle is nearing its end, and flowering occurs for reproduction. Why Darkness is Important for Cannabis Plants?Ĭannabis is a photoperiodic plant that responds to seasonal changes in light.
And whether your greenhouse sits in the Pacific Northwest under long summer days or in the hotter climes of the Central Valley, it’s essential to balance darkness and light for a maximum bud harvest.Ĭontact our experienced cannabis professionals at 76 or start a live chat.
