Thanks to legalization, enormous opportunities currently exist in the cannabis industry. Not at all surprisingly, many people are now relocating to the newly legalized states, to find their fortune growing cannabis as medicine, and for recreational use. With an average value of 3,000-3,500 per pound, for high quality, or top-shelf cannabis, it’s easy to see why. Cannabis is the single most valuable agricultural crop currently in existence, and growing can be extremely lucrative, if you are a skillful grower. Of course, making money this way isn’t just a matter of getting the cannabis to survive and grow, but of getting it to reach its full genetic potential, to flower into the high quality buds that bring top-dollar. In order to do that, you have to know how to use your growing room to create the ideal, internal micro-climate to achieve the desired results.
One critical element is light; as everyone knows, light is critical to the survival of plants. There are a variety of theories about what types of lights are the best, and you can come to your own conclusions after doing your own research, but for the beginning grower, 600 watt HPS lamps will work very well. Each of these lamps will nourish about a 6 sq ft area, which can hold about four fully grown plants, or more if you’re using the sea of green method. This part of the grow room setup is actually relatively simple, and doesn’t require a great deal of detail here, it’s just a matter of getting the right plants:lights ratio, and also making sure the plants don’t get too close to the lights.
The darkness is actually what most people overlook, and causes far more problems than anything to do with the lights. The best cannabis grow room will need to be have absolutely no light leaks. Cannabis growing methods more-or-less center around the concept of mimicking the perfect natural environment for the plants. This means mimicking not only the ingredients of that environment, such as sunlight and water, but also the changing ratios of those ingredients, which in the natural environment would be the shifting of the seasons. So for the flowering stage to be optimally productive, it’s critical that the plants have a full 12 hours of complete and utter darkness, just as they would in the Autumn in their natural environment. This means you must go inside your grow room, and wait a full fifteen minutes for your eyes to adjust, in order to see if there are any light leaks, or light coming from internal equipment, that you need to tape over with light-proofing tape.
Temperature and humidity are also internal climatic conditions of central importance, and they also must mimic the natural seasons the plant would experience in nature. This means that in the earliest phases of the plants’ life-cycle, it must be warm and humid, to mimic the Summer. Ideal temperature for the seedling/clone and vegetative stages is around 75-85 degrees, and the relative humidity starting at 80-90% at the clone stage, and gradually dropping down to as low as 45% during the vegetative stage. When your plants reach their flowering period, just like the seasons, temperatures must drop to 60-75 degree range, and relative humidity to 40% or lower. Low humidity during this final phase, when the buds are developing, will help to avoid powdery mildew from cropping up between the buds.
CO2 is also very important, since it’s the primary gas the plants breathe and require for photosynthesis. Plain old ventilation will be enough to make your plants healthy and happy, but if you want to maximize their potential, you’ll want to supplement with a CO2 tank. The best way to grow marijuana is with CO2 supplementation, and driving CO2 levels up to as much as 1800ppm will drastically increase the quality and quantity of your yields. However, this requires a bit more knowledge and technical expertise, and isn’t necessarily a move for the novice. Also, all of the temperatures for the various stages can be raised as much as 10 degrees if you’re using CO2 supplementation, and if you know you’re going to use it, you can also purchase a stronger light. This is because the plants are more capable of handling light and heat with higher CO2 levels.
Lastly, it’s important that you properly oxygenate your water. To do this, simply purchase a water aeration device, and install it in the water supply. This will help them to grow healthy and strong, because water is the primary way plants acquire oxygen.
