Growing weed in indirect sunlight

Most photoperiod strains tend to begin flowering when the hours of daylight the plant receives drops below 15. Yet, this type of seed is able to stay in its vegetative stage indefinitely as long as it receives at least 15 hours of sunlight each day.

Photoperiod cannabis plants use photoreceptors to sense forms of phytochromes or cytochromes created by light. Therefore, the photoperiod of cannabis can be considered in terms of the hours of light a plant receives over a 24-hour time period.

Sunlight is what encourages natural leaf and stem production in cannabis, allowing it to flourish and reach heights that can far exceed indoor grows. With an outdoor grow, the best yield will come from plants that have the most access to sunlight (in favourable conditions), so this will always be key to take into consideration when moving your cannabis growing skills outside.


One benefit of selecting photoperiod strains is that you are able to take cuttings of your best plants and use them to breed new plants. However, you will always have to pay close attention to the amount of sunlight your plants are getting, and spend a lot more time getting rid of males that could pollinate your crop.

Ultimately, the objective for the outdoor grower is to make sure your plant is getting at least five hours of direct sunlight and five hours of indirect sunlight each day; however, days tend to be longer during the middle of the growing season, where the sun can be out for much longer. As a short-day plant, a 12-12 hour photoperiod is the easiest to work with when planting cannabis, and with most strains, it bears excellent results. Growing cannabis is not an exact science, and it takes time to build the skills necessary to support a flourishing grow—but if you are dedicated to the task, you may be able to achieve great results.


It is important to take extra care when growing this type of seed. You must always ensure that your plant receives 5 hours with and 5 hours without continuous sunlight. Try not to rush over this crucial detail. It is a steep learning curve, but light levels will determine the rate at which your crop grows.

By finding the point at which your plant will be receiving 18+ hours of sunlight each day, you will be able to determine the best period for vegetative growth. The next important factor is finding when sunlight drops below 12 hours in order to trigger flowering and eventually harvest.
