An optimized design for high pressure and quiet air movement, the RAM Inline Duct Fan features the patented Fast-Flow even air-flow fin. The RAM Inline Duct Fan is supplied with a mounting bracket and fitted with an IEC Socket. Hydroponic.co.za also adds a kettle plug electrical cord to the item for your convenience.
What is Fast-Flow?
Fast-Flow is an anti-turbulence fin. This patented technology slows down the air coming into the fan resulting in a smoother and more direct flow of air into the ducting.
Grow tent or grow room ventilation is essential for healthy, fast growing plants and filtration is also key – keeping incoming (and/or circulating air) air as clean as possible.
Replacing the air in your grow space at least every 5 minutes during the room’s daytime cycle if using an “open” system, but definitely quicker if your environment is struggling to combat heat or humidity. ( Up to once every 2 minutes if necessary )
It is also important to circulate the air inside your grow area. This will keep strengthen plants, help with plant respiration and reduce mould risk.
When it comes to indoor growing, a well controlled environment is critical. Good ventilation forms a big part of this.

When growing in an enclosed space, we advise using both an extractor fan and an intake fan. The extractor will remove the moist, warm air (high humidity) along with other respiratory by-products and helps to replenish carbon dioxide. The intake fan should be placed at the opposite end of the growing environment to help control humidity and temperature and introduce carbon dioxide into the area. Having the right ventilation set-up is vitally important to controlling temperature and humidity. Problems like disease, poor growth, yields and pest control issues are associated with a lack in control of these two factors. Ensuring there is a good supply of fresh air in indoor growing areas can be the difference between success and failure and therefore a need for the element of control.
By making sure that you have the right filter, fan and ducting combination, you can save time, money and effort in the long-run. Measuring up your room correctly is highly important to ensure that the correct ventilation system is chosen and its subsequent success of maintaining an efficient growing area.
Some common tent sizes and recommended airflow:
0.6m x 1.2m x 2m = 115m3/hour
1m x 1m x 2m =160m3/hour
1.2m x 1.2m x 2m = 230m3/hour
1.5m x 1.5m x 2m = 360m3/hour
1.2m x 2.4m x 2m = 460m3/hour
2m x 2m x 2m = 640m3/hour
2.4m x 2.4m x 2m = 920m3/hour
