Your Grow Room environment should be one of your first considerations for a successful hydroponics setup.
If you provide your plants with plenty of fresh air, you effectively guarantee a generous supply of carbon dioxide, which plants need for their healthy growth and development.
Proper ventilation in your hydroponic growing area or tent is essential for healthy plant growth. For your plants to develop as they should, it is necessary to clean the air and remove any nasty particles from the environment as much as possible.
Air constantly circulating within any given confined space will also be a good defence against the various biological hazards that can develop over time.
There are well-known diseases that affect plants. These can be kept at bay and under check better if you have a gentle breeze that does not permit local buildup of the kind of micro-organism and bacteria that cause these diseases in the first place or allow them to flourish.
