Breaking Down Fans
Fans play a major role in any grow project set up. The movement of air in and around plants is key in allowing photosynthesis to occur and plants to grow. Plants need CO2 to photosynthesise and generate oxygen in this chemical reaction which is then released back into the environment. Plants need a constant stream of CO2 to carry on growing and a fan will ensure that fresh air is pumped in to your grow room/tent so your plants can thrive.
Fans also keep air moving around your grow tent which helps stop the build up of moisture on the plants, medium and growing environment. Anyone who has experienced this moisture build up knows that it will not be long before mould and disease begin to appear which can spell the end for any grow project!
Having the right fan set up for your grow environment will ensure you can provide your plants with what is needed to continue growing whilst keeping in control of any potential hazards that can put your project at risk.
All fans are not made equal!
Fans can be broken down into two main categories. AC & EC. AC funs run on an alternating current where as EC fans run on a combination of AC & DC current which has made from mains electricity by a power supply. AC are the older and more established fans whilst EC and the newer and slightly more upmarket options for growers.
Which is better? AC or EC?
Both AC & EC are great options for your grow space. However, they range in effectiveness based on what you are looking for.
Which is cheaper to purchase?
AC fans are cheaper to buy than EC ones. Mainly due to the fact the technology involved in an EC fan is far more complex so you are paying for the higher level of control on offer.
Which is quieter?
With many indoor grow environments being indoors or near to people, the amount of sound they emit can be a game changer when it comes to choosing your equipment. EC fans use a lower voltage to produce their power and this is finely controlled by the device so you will get very little noise and certainly no ‘hum’ from your fan at any speed. This is not the case with AC fans which are known to create noise, especially at low speeds. You can buy controllers for these AC fans which will eliminate some of these issues, however, you are then paying more which would move them closer to the price point of an EC fan.
Which is cheaper to run?
EC fans give you the most precise control over your speed in relation to your growing environment so overall they will give you lower running costs. AC fans will cost more to run but that is the price you are paying for a lower initial outlay.
Which fan will give the better yield?
The all-important question! When it comes to yield, environmental control is everything. The better and closer control you have over your growing environment, the more likely you are to get a better yield. EC fans offer a much more precise control over air intake and extraction and so they have the potential to outperform AC fans here. Although, with AC fan controllers you can definitely close the gap.
Overall, both AC and EC fans can provide you with the tools to take control of your grow projects air flow. When you find the right fan which meets your budget and needs you will be set on your way to some great yields!
