Cannabis can grow in any environment that fulfills the basic requirements of providing light, water, and air. This page
== Outdoor ==
When growing outdoors a key consideration is when to plant seeds for optimum light and temperature conditions. It is best to know the DLI your plant will
== Indoor ==
While growing indoors it is crucial to monitor and adjust the environment's [[Temperature and Humidity|temperature and humidity]] as there is no natural mechanism to regulate these factors. Data from [[Environment Sensors|environment sensors]] will give the best indication of if the environment is sufficient but there are also[[Symptoms of bad environment|symptoms of a bad environments]] that can be helpful in determining sufficiency.

==== Raising humidity ====
Raising the humidity of your growing environment can be most easily achieved by adding an electric humidifier or diffuser to the space. Alternatively, placing a wet towel in the area will help to raise humidity.
==== Lowering humidity ====
Electric dehumidifiers are a simple option for lowering humidity but they may be too large for your grow area, a more compact option is to use a chemical
==== Raising temperature ====
Generally speaking, the easiest way to raise the growing environment temperature is to raise the temperature of the room it is in. If this isn't possible then raising the light intensity or adding an
==== Lowering temperature ====
Temperature can be lowered by increasing the rate of airflow from inside to outside the growing environment, in other words, increasing ventilation. The light being used may also be adding to the temperature so decreasing its intensity, where possible, will lower the temperature.
=== Adding extra Co<sub>2</sub> ===
Very high levels of Co<sub>2</sub> (>1,000ppm) can induce headaches and sleepiness<ref>https://www.kane.co.uk/knowledge-centre/what-are-safe-levels-of-co-and-co2-in-rooms</ref> so be sure to buy a sensor to ensure you are exposed to safe levels.
To increase Co<sub>2</sub> concentration to a high level in the grow environment the enclosure must be sealed to prevent the gas from escaping. Ventilation must also be reduced or disabled. There are two main methods of adding Co<sub>2</sub>: using a tank with regulator and tubing into the grow space or using a chemical reaction that produces Co<sub>2</sub>. Co<sub>2</sub> is heavier than air so however it is attained it should be inserted above the canopy so that it falls onto the plant. Fans on the floor pointing upwards can also help direct Co<sub>2</sub> from the floor into the leaves.
