Horticulture Grow Room Ventilation & Filter kit

duct fan, filter, ducting, fan speed controller, and duct tape

At Holland Hydroponics, we are proud to feature quality ventilation and filter system, the best-selling system on eBay! Our flawless ratings, feedbacks and praises are not just vouches of excellence but returning customers, ranging from single-light to hundred-light setups, time after time. With Holland Hydroponics, you are not buying a re-brand or a knock-off, but a high quality, genuine Quality equipment directly from the manufacturer with great customer support and factory-backed warranty. 

Ventilation is essential for plants to grow, when you are growing hydroponically in a tent or room that is sealed. You will need to remove any hot stale air and supply clean fresh air, for your plants to survive and we stock all the tools you will need to control the environment

One of the most important factors to maintaining a good grow room, is the environment in which the plants are grown and ventilation is essential for your plants to flourish.

The supply of clean fresh air rich in Co2 into the grow room and the removal of hot stale air from the grow room must be done for you to maintain the required temperatures for the type of plants you are growing.

The idea is to create a negative pressure in the grow room, which allows the same amount of air to flow into the room to match the amount that is being extracted out. If too much air flows into the grow room that exceeds the amount going out, it will probably help to push odours and pollens out of the grow room and into your house. If too much air is extracted and not enough air flows into the room, it will create an air flow directly from your inlet hole, to your outlet hole and some plants may suffer from a lack of clean fresh air around their foliage.

SETTING UP A VENTILATION SYSTEM

First you must completely seal the room you have chosen, this will help to eliminate the risk of any pests entering uninvited and also allow you to control the temperatures inside much easier.

You must create an inlet and an outlet hole, that are on opposite corners of the room and of course the inlet hole should be fitted at the bottom of the room and the outlet hole at the top. This allows your extraction system to be mounted as high as possible in your room to ensure all of the heat that is produced is removed efficiently. Once this is done, you can fit a
Wall Spigot over both the holes with some no nails glue, to easily fit your ducting with some tape or a jubilee clip.

A
Carbon Filter can now be mounted at the highest point of your room and an inline fan connected with the flow of air pointing in the direction you want the air to travel. Inline fans can be connected directly to carbon filters with Fast/Quick Release Clamps or they can be mounted with a piece of ducting in between. Inline/Duct Fans are used to move air quickly through ducting and there are several different sizes available to suit different size rooms. Aluminium Ducting or Acoustic Ducting can then be fitted from the inline fan to the outlet hole of the grow room to complete the extraction system. Acoustic Ducting helps to reduce the noise of the air travelling through and if your fans are too noisy you could use a Fan Silencer (not included in this selling package, it is optional item and it is available in my store) fitted inline into your ducting from your fan.

For the inlet you will just need some ducting and a fan. Of course this opens the grow room to the great outdoors and invites anything to enter, so it is wise to cover the inlet hole with some fine mesh or a stocking.

This will now provide you with a passage for clean fresh air to enter the grow room and also hot stale air to escape, but it does not provide much air movement inside the grow room so you will need to use a fan to circulate the clean air that enters, around the room and amongst your plants.

AIR CIRCULATION IN THE GROW ROOM (optional items in my store)

There are many different types of fans suitable for circulating air around in the grow room and also different sizes. For small confined spaces or grow tents, a Clip Fan is perfect, providing an adjustable head for directing the air flow just above your plant canopy. For larger grow rooms Wall & Floor Fans or Oscillating Pedestal Fans

can be used, moving much more air amongst your plants and their foliage. You want your plants to move gently in the breeze and not to be blasted by a tornado of air, as this will cause more harm than good. A gentle breeze will help to strengthen stems as plants grow and most importantly it will help to prevent any mould setting in when you are flowering your plants to bear fruits.

You can find these fans from my store under category "Fan & Ventilation" as additional item to purchase

http://stores.ebay.com.au/Holland-Hydroponics/Fan-Ventilation-/_i.html?_fsub=4137831016&_sid=1137544806&_trksid=p4634.c0.m322

 

FAN SPEED CONTROLLER and HOT & COLD THERMO CONTROLLER (optional items in my store)

To maintain the temperatures better in the grow room you can connect your fan or fans to a Fan Speed Controller. A single Fan Speed Controller with a Thermo Controller will automatically help maintain the temperatures inside the room.  As the room heats up and the temperature you require is exceeded, the fan will click into full speed to lower the temperature back down to the temperature set by you.

You can find these controller in my store under " Timer & Controller"

http://stores.ebay.com.au/Holland-Hydroponics/Timer-Controller-/_i.html?_fsub=4454329016&_sid=1137544806&_trksid=p4634.c0.m322

MEASURING YOUR GROW ROOM

The size of the fans you will require will greatly depend on the size of the grow room and it can easily be calculated to match the room size with the correct size fans. If you do not match the flow of air required with your ventilation system, you will most certainly struggle with your temperatures, it is always better to go slightly higher than required, rather than trying to cut corners and save some money with smaller fans fitted.

The grow room will need to be measured in metres, the length, width and height. Once you have the measurements you can calculate the room size into cubic metres to find the volume of the room and then you can times it by the amount of times you want to exchange the air in the room each hour. This will give you a guide to the size of the fans you require, but it is also important to take into account your light or lights as they will certainly add additional heat into the room which will need to be removed quickly. Adding extra to account for each light in the room will help you to maintain the temperatures much easier, so as we say it is better to go slightly higher than required by your measured calculation. Also the carbon filter will reduce the air flow a little from the extract fan, so you might find you need a slightly larger extraction fan, compared to your inlet fan.

Below is an example of a room with two 600w grow lights hung inside.

Room size = 3 x 2.5 x 2.5 metres = 18.75 cubic metres

To exchange the air in the room every two minutes (recommended) you will now need to times the cubic metres by 30. As there are 60 minutes in an hour, 30 divided into 60 equals two minutes.

18.75 x 30 = 562.5m3/h

A fan that moves more than 562.5 cubic metres of air per hour would be required for the inlet and outlet hole of this room, but of course with the carbon filter and two lights, the outlet fan and carbon filter would need to exceed this amount to balance the air flow for a negative pressure to exist in the room.

Adding about 20% = 675m3/h to the outlet would certainly compensate for the filter and lights and would help to maintain the environment much easier.  Therefore a 6" duct fan with 690m3/h air flow listed in the table below will do the job for this size of grow room.  Of course you may select a 8" duct fan with fan speed controller just to be on the upside or have air exchange less than 2 minutes of your choice. 

 All electrical items have fitted with Australian Power Plug and Standard Lighting Socket.
