Light-deprived crops need to have their CO2 and oxygen levels monitored closely. Grow lights produce heat, and plants use up the carbon dioxide (CO2) in the air. To avoid accumulating too much CO2, it is important to change the air inside a grow tent or room regularly through an extraction system. Replacing the hot, stale air with fresh outside air helps to cool down and oxygenate grow rooms. In addition, an intake fan can help get rid of old CO2-rich air faster.
Grow lights produce heat, which can cause a rise in the temperature of an enclosed space. Plants use up carbon dioxide (CO2) from the air to help them grow. To assist with the replacement of the air, some growers also use an intake fan. The result is that your grow room or tent will feel hot and close if you do not have any way to change out the air. This can cause headaches, dizziness, nausea and excessive sweating for those who spend time in a grow space without proper ventilation.
Negative air pressure is a key aspect of any grow space and is essential to keep smells from getting out. This means that all air leaving the grow tent or room does so via the extraction system with a carbon filter connected. This ensures that all odours are removed before it exits the grow space as negative air pressure inside keeps it in. An extractor fan and carbon filter combination should be installed in your grow tent or grow space to ensure that no odours escape via cracks and ducting. The extractor fan creates negative pressure inside the grow area, which helps keep air from being pulled out of the tent. By removing all smells from exiting air, you can ensure that unwanted odours will not get out of your grow room/tent/space and affect either neighbours or passers-by outside.
