Fans, Filters and Accessories

Having a good healthy growing environment for your plants is of paramount importance. At Esoteric Hydroponics, we can offer advice on all ventilation and environmental control requirements. Visit our shop or contact us. Good air circulation is an important factor in any growing environment. An extractor fan is required to bring fresh air from the outside, into the growroom and another extractor fan is needed to remove the stale air. On some occasions, only the one extractor might be used to extract stale air from the grow room and the fresh air is replenished through vents in doors, windows and walls.

An adequate supply of CO2 in the growing environment is probably the main reason why an extractor is a requirement. Plants will quickly use all available CO2 in an enclosed environment, which could lead to slow growth of plants. Our range of extractor fans and environmental control equipment will ensure that you get the best results everytime.

With extraction it is very easy to over do it or under do it, so it is therefore very easy to get it wrong. We operate a "suck it and see" policy where if you get it wrong you can come in and exchange the extraction / carbon filter / ducting / spigots for the right ones. You pay the difference if upgrading, we pay the difference if downgrading. This is only applicable for 2 weeks after purchase.

Fans

The RVK range of fans made in Germany by LTI are quiet and powerful. They are also ideal for connecting to our range of carbon filters. The LTI extractor fans come fully recommended. If you are not sure what size extractor fan to use, it's easy to work out. Simply calculate the volume of the growing environment to the nearest cubic metre. This is done by multiplying:

Length x Width x Height = Volume of your room in cubic metres (m³) and then multiply the answer by 20.

Ideally, air needs to be replaced every three minutes (or twenty times an hour). Therefore, just multiply the volume of your growroom by 20. Measure the height, width and length of your room before contacting Esoteric Hydroponics.

For example, a room of 3 metres x 4 metres x 2.5 metres high = 30m³ and 30m³ x 20 changes per hour = 600m³ per hour. Once this has been calculated, you can select the correct fan.

Combinations of different fans can be used.

These extraction fans are second to none. They are industrial low wattage, high output fans that are designed for the job in hand. These fans can be run 24 hours, 7 days, 356 days a year without any hassle or problems. In fact, this is what they have been designed for. Don't buy cheap and end up buying twice; cheap extractors are meant to be on and off for short periods of time - these ain't.

The LTI/RVK extraction motors are completely silent however, the air flow is not. If noise is a problem then stick one carbon filter on one end of the extractor and a silencer on the other end and hey presto, one noiseless extraction unit which is also odour free.

Please contact or visit our shop if you are in any way unsure or need clarification of which size of fan to choose - it's important to get the ventilation right.

Odorsok Carbon Filters

Odour problems are in the bag! This multi layered carbon cloth bag sets new standards for carbon filters in every way. Carbon filters, Full of innovation and versatility, some of the many benefits include:

- Unbelievably light - weighs <4lbs boxed.
- Stores at under 1/12th of its working size.
- Freight easily in the post without damage.
- Easy to assemble and disassemble.
- Average 8% air loss with centrifugal fans.
- Work in humidity - Tumble dry when wet.
- Air flow capacity from 100 to 2400 cf/m.
- Sizes inc: 4, 6, 8, 10, 12, 14 & 16 inch.
- Fits any fan and comes with duct tape.
- Substantially cheaper than carbon canisters.

You will not believe how effective the Odorsok filters really are until you try one for yourself.

So how do they work? Odorsok Air Filters are constructed using bundles of microscopic activated carbon filaments and fibres. By controlling fibre width to 20 mm, the kinetics (absorption rate) of carbon cloth is similar to that of a single exposed carbon particle. Air flows evenly across the carbon and with accelerated kinetics (up to ID-2400) and increased surface area, Odorsok Air Filters retain all the properties of deep filter bed canisters. Faster absorption rates means smaller filter equipment and up to 30 times less carbon in use for the same result over a 1 year period. That's how!

These are the best carbon filters around. Unwanted odours can be a problem for indoor gardeners. Whether you are growing peppers, strawberries or your favourite herbs, carbon filters will remove any odours that come from your crop. Carbon filters work using activated granules of charcoal by which odours are extracted through the fans.

Installing a carbon filter is easy and takes just a few moments. Usually, the activated charcoal in your carbon filter will last for a minimum of 12 months. Carbon filters are an essential accessory if you are concerned about unwanted odours. Full instructions supplied with every carbon filter.

Rhino Pro Filters

How long will a Rhino Pro Filter last?

Unlike all other carbon filters with effective life spans of 9 to 18 months, Rhino filters have always been known to have an out lasting performance for well over two years. Replacement carbon sleeves are available to make them last even longer.

We feel there is a massive misunderstanding that all carbon filters are the same. They are not. We use best quality carbon money can buy, to ensure our filters have good air flow and better life span. Rhino filter use 100% Australian carbon. Do not be fooled by the claim that carbon is carbon.

The Rhino Pro Filter is constructed from Australian-mined RC412 carbon, the best in the world. The carbon is tightly packed and sealed into a high-efficiency airflow cylinder with a vortex cone in the base and a custom pore surface for maximum transference. The high-porosity carbon and lightweight aluminium make the Rhino filter smaller and easier to handle.

• 50mm bed of RC412 activated carbon.
• 1.6mm aluminium tops and bases for reduced weight.
• Unique “Anti Air Bypass” system.
• 51% open area custom mesh for greater air flow.
• Machine packed carbon means more carbon and less movement.
• Coned internal base for optimum air flow
• Sealed, boxed and labelled directly after manufacture for optimum lifespan, handling and presentation.
