What type of lighting to use in indoor growing
We review the different lighting systems for indoor crops, their advantages and disadvantages, so that each grower chooses what best suits their needs.
Cannabis needs sunlight and the passing of the seasons. This way you know when to stop growing and start flowering, as the days get longer and the daylight hours increase. However, for so many plants around the world, the sun may well not exist. It is as unknown to them as the sea could be to a monk high in the Himalayas (we assume that this monk never went on vacation). It is about the millions of indoor crops that supplant the sun by lamps of different types that give plants the energy they need, and determine their cycles. There are several types of lighting systems, each with its own characteristics and suitable for different types of crops.
In order to make a good choice, you first need to know what is the appropriate light spectrum for cannabis. To reflect what happens in nature, marijuana plants basically need blue light during growth and red light during flowering. The green spectrum does not affect them, so if it is necessary to use a light in the crop without altering the cycle, a lamp of this color is suitable.
Another very important factor is heat. The different types of lamps emit more or less temperature, which must be taken into account. Although the more watts, the more production, this has a limit. More is not always better, especially in tight spaces or naturally hot climates. The most commonly used powers are 400W and 600W with their ballasts.
Lighting systems for indoor growing
Each lighting system has its pros and cons, and even its functions. Different types can be combined, or choose an integrated system. Let's see the different options:Fluorescent tubes and CFL
In the early stages of the plant, it needs less light output. For this reason, fluorescent tubes or CFL (Compact fluorescent light) energy-saving lamps are ideal for germinating seeds or rooting cuttings thanks to their blue light spectrum and low consumption. They are inexpensive and easy to use. CFLs also come with a built-in ballast. In terms of power, fluorescents range from 18 to 55W per tube, and CFLs are 100, 125, 200 and 250W. Due to this low wattage, a good number of bulbs are required for efficient lighting. There are CFL bulbs in the red spectrum, which can be used for flowering, but may not be the best option.HID bulbs: sodium (HPS) and metal halide (HM) lamps.
Both sodium (HPS) and metal halide (HM) lamps are types of HID (High Intensity Discharge) bulb. In general, these are two types of complementary lighting, since HM are more appropriate for growth (due to their blue spectrum), and HPS for flowering (because they are rich in red). Both usually use the same ballast, but for this it must be taken into account that both are of the same watts. The most common is that 250W, 400W and 600W are achieved.HPSs are known for their great performance, but they generate a lot of heat, so it may be necessary to install a ventilation system. In addition, they can result in high energy costs (with its consequent electricity bill). All HIDs degrade over time. HMs do it faster than HPS, but both require replacement after a few crops. There are also mixed versions, which are HPS lamps with dual spectrum, that is, for growth and flowering, such as the Dual Spectrum from Lumatek or the Son-T Pia Green Power from Phillips.
