RVK inlet and extractor fans are an essential part of your grow room setup, without them your rooms' environment would not be suitable for growing and your yeilds will suffer.

RVK ducting fans can run 24hrs a day, 365 days a year without burning out.  They create a huge amount of pressure and are the best choice for moving lots of air through ducting.

These fans are exceptional value for money providing efficient air circulation and ventilation.

People often underestimate the importance in using the correct fan for the job.  Using the correct fans will improve the health and productivity of your crop by creating correct air movement.  See our article on Temperature, Humidity & C0²

It really depends on where you are growing as an attic space will often require more airflow than a basement due to the coolness of a basement.  In general you want to change the air in your grow area completely at least 20 times per hour.

We recommend you take into account the size of the room and how many lights you are using.

As a general guide:

• Choosing the best fan for you.
• How to silence my fans.
• Temperature Humidity and co2.

Now dual purpose - They will clip on and stand up

These uplift fans are a must for tent growers,

• Allowing you to mix unused co2 from the bottom of your space
• Mix hot and cold air to ensure even temperaturs
• Low energy
• Small and compact

Oscillating fans are an absolute must for a good grow room.  They move the air around the room aiding in plant health, growth and environmental control.

Circulation or mixer fans, which may be wall mounted or pedestal types carry out the essential function of mixing the cooler, drier fresh air being brought in, as well as any CO2 enrichment to create a perfect constant temperature and prevent cold drafts from stressing the plants.

These fans should be placed carefully because the main objective is to not only get air circulating and mixing in the lower levels of your crop to reduce humidity and disease problems, but also over the tops of your plants to help achieve maximum growth and yields.

The Primair Controller is an indoor climate controller, designed to be used with extraction & intake fans, it will maintain temperature in an indoor growing environment through the use of a thermostat.  The Primair Controller is also fitted with a speed control mechanism that will control the speed of two fans.

The Primair Controller works simply by wiring both your inlet and exhaust fans into the unit and setting the desired temperature.  Once the fans are wired in you can then set the speed control mechanisms to give you even more control over your environment & fine tune the climate controller to your own specifications.

The fan runs at max speed when it gets too hot and the variable controls the off settings independently for each fan.

This digital temperature sensor and controller unit is one of the most reliable and effecient on the market. Constantly monitoring the temperature and humidity in your grow area and constantly adjust the fan speed to optimize conditions for plant growth.

Set desired temperature and percentage reduction in fan speed. When the air temperature at the sensor exceeds your desired temperature the fans will automatically adjust their speed.

CO2 release system with over 120 preset ranges to suit most rooms.

Raise the humidity in your room with these handy foggers.  They come in two sizes, one that will do smaller area and one for larger spaces.  Just sit them in water and plug them in.

You can run them constantly or on a timer, depending on the amount you need to raise the humidity.  They come with a cut off switch to stop them running if the water runs out.

These, simple to use, memebranes are replacements for either the mini fogger memebranes or the large fogger memebanes.

Carbon dioxide (CO2) is essential for plant growth. In an enclosed growing area, as plants use up available CO2, their growth will slow down and may eventually stop. Replenishing CO2 will not only maintain growth but dramatically increase it. The average level of CO2 in the atmosphere is about 350 PPM [parts per million]. Through years of agreed upon practice, the optimum level is in the 1000-1500 PPM range. At these levels it is not uncommon to realise a 25-40% increase in yield. In the absence of CO2-enrichment equipment, the common way of replenishing CO2 content in an enclosed growing area is by an extractor fan. This draws in fresh air and with it ambient levels of CO2.

*Please note: CO2 bottles cannot be sent - only picked up from shop.

These two high quality centrifugal humidifiers are extremely powerful and both come supplied with an integral humidistat to ensure that optimum humidity is maintained. The HR-15 humidifier should be used in grow rooms with 4-6 lights and the larger HR-50 for grow rooms with 10-15 lights. Require a separate reservoir or alternatively you can purchase one of our complete kits which include a 100 Litre Space Sava reservoir and the necessary pipework to create a fully operational humidity system.

Humidity is a severely underrated factor when it comes to optimising plant performance and final yield. Too often indoor growers opt for the safe approach of very low humidity to avoid any potential rot or moisture related problems during flowering or fruiting. The truth about humidity though is that most plants actually thrive in more humid conditions, especially during the vegetative growth stage where ideally you need to maintain 50-70% relative humidity.

Its time to take your indoor gardening to the next level with Co2Boost. Just plug in our Co2Boost pump and watch as your plants health and size increase daily! If used properly, Co2Boost provides your plants with Co2 for a full 90 days.

How does it work? CO2Boost works from a combination of all-natural compost ingredients. Those ingredients are mixed and put in the bucket where the CO2 is then naturally created. The air pump carries the CO2 out to your plants.

How long does it last? Our product lasts at least 60 days if used constantly. If you use a timer on the pump to coincide with your lights on phase, it will last you 75-90 days. We suggest one bucket per growing cycle to be safe.

Can I half use the bucket then store it for later? No, once activated it has a maximum life of 90 days.

Does it smell? No, even though it's a 100% organic product it is completely odorless.

Is too much CO2 harmful to plants or pets? Yes, but this product does not produce enough CO2 to be harmful.
What size room? From 60cm square up to 3m x 2m. In the smallest growchambers put the timer to half of the time.

Is there anything dangerous contained in the bucket? No, our ingredients are 100% all-natural and harmless. Once your bucket has expired you can use the remaining ingredients as high-grade fertiliser in the garden!

Growth Gas Generator is a dedicated CO2 production unit, designed specifically for the small domestic greenhouse or indoor growing area.

It burns readily available Propane Gas to produce copious amounts of CO2 and can easily be controlled by a timer to ensure that CO2 is produced at the right time of day.

Output - 1.25kW Output.
Supplied with Installation and Operating Instructions

• How Carbon Filters Work

The Unvonair di-ioniser will eliminate the odours by generating ozone which interacts with the air and strips all odours from it.

It will completely neutralise all odours at the source for this size area.

Sizes:

• 1000 - Works in areas up to 1000ft²
• 3000 - Works in areas up to 3000ft²
• 5000 - Works in areas up to 5000ft²

At 3,000 rpm, the PureAire sprays the mixture into the incoming polluted air. Resulting in a scrubbing effect, eliminating enveloped viruses, bacteria, malodours, fungi and mould in the process.

In addition, it converts positive ions into negative ions and at the same time humidifies and combats stagnant air from central heating systems and air conditioning units.

The VaporTek unit uses a sophisticated fan/heater system to deliver odour neutralising gel to the atmosphere it uses replaceable cartridges which will last approximately 3 months (depending on use).

This compact electric unit comes with one cartridge and is ready to use out of the box.

The two speed air purifier features multistage air cleaning and exclusive adjustable odour control.  Only Vaportek's Air Purifiers use Vaportek's patented odour control membrane system.

These small packets "breathe" out a non-toxic deodoriser vapour to control malodours fast.  Independent tests confirm that this air purifier is capable of removing more than 99% of pollen and over 95% of atmospheric dust.  Filters and replacement membrane kits are designed to be replaced every 90 days.

Odour Killer originated as a natural odour control product for industrial use.

Ona safely eliminates all odours in even the most confined areas.  It is not a masking agent and does not operate in the same way as some less efficient counteractants, instead it creates a neutral atmosphere where odours are removed but no replacement odour created.

The block is the little brother of the gel.  Good for smaller areas.

Take the ONA odor block out of the container and place in the area where odors lurk. The duration of the ONA odor block will vary from 15-30 days relative to the airflow around the block and the ambient temperature.  To reduce the strength of the block, poke holes in the cover and replace on the container.  This will also prolong the life of the block.

We have fresh linen smell available in this.

ONA Liquid can be used to reactivate the gel when it has dryed up and it can be added to commercial misting systems, humidifiers or simply sprayed freely into the air to neutralize airborne odours on contact.

This is the replacement cartridge for the vaportek air treatment system.

These are the replacement part to the Vaportek Purifier we recommend using only vaportek replacment as they are longer lasting and help your room smell fresh and clean.

Insulated ducting is basically regular ducting surrounded by another strengthened sheaf containing fibre glass which deadens and absorbs the sound of air as it passes through.

Insulated ducting does not silence extractors but dramatically reduces noise output instead.  Use it as you would use normal ducting.  For best results use on both the input and output sides of your extractor fan.

Easily-fitted silencer for circular ducts, fitted with a connection that complies with the spiral duct standard.  The LDC effectively reduces noise in the duct.  Two silencers can be used together in installations where noise reduction is a particularly strong requirement.  This is very effective.

For the most effective noise reduction, the silencer should be fitted immediately behind a fan or bend.  The silencer should be used together with an insulated fan where there is a requirement for noise reduction both in the duct and in the surroundings as a whole.

Sizes Available: 100mm - 200mm are 600mm in length

                          250mm & 315mm are 600mm in length

Metal wall flange with one side for permanent attachment and the other for connection to flexible ducting.

Distribute your airflow evenly around your room.
