We’ve already seen essentially how the plants should be watered and how much light they should receive. During vegetative growth, the plants are likely going to become “thirstier” and require more water as they get larger. The same rules still apply when it comes to watering: don’t severely overwater and don’t severely underwater. Many growers develop patterns for watering their marijuana plants. For instance, you might water one day, skip watering for two days, and then water again. It really all depends on the plants themselves.
You need to pay close attention to exactly how dry the soil gets after a few days. If the soil is still moist, then you can probably continue on the same pattern, but, if it dries out significantly before the next scheduled watering, you should increase the rate at which you water the marijuana plants. When it comes to light, marijuana requires a lot of it. In fact, it is feasible to keep the lights on 24 hours per day to achieve the maximum growth potential. Adjustable light tracks are ideal when you have a large grow room and little electricity so that you can move the lights around to every part of your garden. This way, every plant gets intense amounts of high-quality light. Try to keep a sharp eye on the distance between the lights and the top of the plant canopy, 20 to 30 inches is usually perfect. The accelerated rate at which the plants tend to grow will cause them to inch closer to the lights almost on a daily basis. So, be sure to place the lights close enough so that they provide adequate light energy, but far enough away that they don’t burn the tips of the leaves.

If you want to avoid this, you can install an air-cooled or water-cooled system that will essentially reduce the heat that the lights produce. One of the things about electric light bulbs is that they produce both light and heat whenever they are turned on. Of course, if you let them go unencumbered, they can produce incredibly hot temperatures. But, if you want to make use of all the light they have to offer, a cooling system will allow the lights to get closer and work better in the long run. It should also be noted that certain lights emit different color spectrums. When we talk about visible light, we’re referring to all the colors that we can see which is often represented as ROYGBIV (red, orange, yellow, green, blue, indigo, and violet). Marijuana tends to thrive under light that is strong in the red spectrum. This promotes photosynthesis which is vital for tissue production during vegetative growth. High-pressure sodium (HPS) lamps produce the most light in the red spectrum (and the most light in general) and are often the best choice during virtually every state in the growing process. Using anything that is high in the green spectrum will produce wilted, unproductive plants in general. This is largely because the plants reflect green light entirely, which is why they are green in color themselves.
