Whether you call it weed, cannabis, pot, or marijuana, the plant cannabis sativa is actually easy to grow both indoor and outdoor. Weed needs water, light, nutrients, and suitable air along with right ventilation and temperature to grow in a healthy way. Moreover you need to take care some of the major factors to grow weed in your hydroponic garden, such as:
Grow area: If you are growing weed indoors, you need to select grow room carefully. Usually, a good place to set up your general hydroponic grow room is in the basement. Since it is naturally insulated by the foundation, temperature management would be easier for you.
Light: The size of your weed grow room will determine your hydroponic lighting set up. Metal Halide or High Pressure Sodium is generally used to get healthier plants. During the vegetative stage, keep the light on for minimum 18 hours per day.
Grow room environment: Constant air circulation is very much necessary for your weed plants to thrive. Try to maintain grow room humidity during vegetative phase between 40 and 55 percent. Total C02 for the grow room should be between 800 and 1200 parts per million during lights-on cycle.
Water: Remember, the larger your weeds grow room is the greater your water demands. Hydroponic growing needs adequate amount of water and for that you need a good access to water.
Nutrients: To thrive healthy, weeds need appropriate diet, so it is essential to endow them proper hydroponic nutrients. Plants need nutrients with N-P-K format, i.e. nitrogen, phosphorus, and potassium along with trace elements to grow and get their food.
When an infection will occur in your weed garden, the insect populations will grow rapidly. Therefore, once the pest is identified, try to find predatory insect that feeds on it or you can get proper hydroponic gardening supplies to get rid of it.
