Where do you vent a hot air from a grow room?

May, 2022

This is because the air in the growing room is constantly replaced, preventing heat and moisture from accumulating. The following guide shows you what you need to know about setting up your ventilation system. Remember to use pipe clamps to keep everything in place and have tape handy to cover up any cracks in your system. By providing fresh air from outside your grow tent, you supply your plants with CO2 and drive their photosynthesis.

Once your lights, filters, and fans are installed in your tent, connect everything with air ducts.

Does a sealed grow room need fresh air?

You don't want so much CO2 entering your home and potentially putting your loved ones at risk. Growers need to manage ambient humidity, perspiration, evaporation, heat load peaks, and equipment that is not specifically designed for cultivation and can contribute to humidity. CO2 only works at a very high level, which means you need a sealed grow room or grow tent setup to get the concentration high enough to be worthwhile. For growers in states where cannabis cultivation is still severely restricted, it's understandable that some may have concerns about exhausting outdoor garden air, but with careful filtering, it can still be done discreetly.

The main concern with air exchange is that plants like humans and animals need fresh air. Should you add CO2 to your grow space? Adding CO2 is something to consider once you've optimized all other aspects of your system because it's most effective in an optimized environment.

How do you vent a grow room without windows?

While window openings serve as a “quick fix” to get a garden going, you should probably be looking for something safer and more durable for permanent operation. If you don't condition the air, vent the grow tent and that same air is back in the tent. Although these kits are often easy to assemble, you still need to do a bit of design work to figure out where to place them. It may not seem like much to you, but a few degrees of temperature can be the difference between a successful harvest and a less successful harvest.
