Light is a necessary part of cultivating Marijuana plants indoors or outdoors. Though it is good to have these plants growing under natural sunlight, constraints like space, cost, climate, and other resources make indoor cultivation a better option. In this new post from Plant Sily we will discuss growing these beautiful plants under an appropriate indoor environment. Read More Here on the various types of lights available for promoting the healthy growth of these wonderful medicinal plants indoors.
Importance of Light in indoor cultivation:
Light helps in the photosynthesis process that is much needed for the healthy growth of marijuana plants and also to increase the potency of the buds. In fact, it also controls the budding and flowering phase of cannabis plants. The grower can actually control the budding and flowering phases with a good controlling of light. Being a photoperiodic plant they are exposed alternatively to 12 whole hours of uninterrupted light and dark to make them flower. The Lighting needs to be just adequate, excessive light could burn the leaves, while, lesser light could hamper the plant’s growth. Successful indoor cultivation needs adequate light sources, hence the selection of a correct type of light is a very important task.
Types of light sources available:
There are 3 major types of lighting available in the market the CFL, HID, and LED type lights.
Compact Fluorescent lights (CFL) are the small, low intensity, twisted lamps which are a really good choice especially for those want to grow these plants at a lower cost. These are effective during the initial seeding and germinative phases of plant growth.
Fluorescent lights are great for growers on a tight budget or those working in tight spaces, as they are easy to install and usually don’t take up as much room as other types of lights. Unfortunately, fluorescent lights won’t really do the job once your plants flower, although they can be useful for the seedling and veg phases. Next is the High-intensity Discharge (HID) that includes High-Pressure Sodium (HPS) lights and Ceramic Metal Halides (CHM) type lights. These produce an ample amount of light and are a good choice espicially during the budding and flowering phases of plant growth much exposure could cause damage to its leaves. This is also one such light type that produces more heat hence one must also keep in mind not to
The third type is the Light Emitting Diode (LED). the LED is way powerful than CFL and HID lights at the same time they also produce the least heat when compared to the other two. These are also among the expensive ones due to the incorporation of the cooling system. These lights don’t harm the plants or burn their leaves. These lights are easier to set up and last longer than the other two types of light.
How Much light is needed?
A grower needs to prepare the grow room with adequate lighting. To decide on the exact quantity of light for the crop, find the area by multiply the length and width of the grow rooms. In general, It is said that for every 10 sqft of grow room space needs 30000 lumens. The maximum suggested intensity is 80000 lm over 10 sqft of garden space. The only issue with having marijuana plant indoors is that they need more devotion and needs the cultivator to keep a check on the light intensity and its exposure over time. Thus maintaining the time, energy, money are some of the most important factors to be concentrated while growing marijuana.
