Meters

These CF / TDS and pH meters are extremely robust and of a high calibre and come highly recommended. The conductivity (CF / TDS) meters and pH meters are used in testing the strength of nutrient solutions.

These high quality instruments are designed to withstand the rigours of any growing environment. Both meters feature automatic on / off and automatic temperature control and is accurate to + / - 0.1. These meters require no calibration, come with battery and have a two year guarantee.

When using NFT, Flood And Drain and Rockwool slab culture, growers can control and manage the pH and strength (conductivity or CF/TDS) of the nutrients and ensure fast growth rates and greater yields.

Fully waterproof meters shown above, well worth the extra initial outlay.

Meters are tested at the shop at time of purchase, and come with a 90 day warranty. pH meters should last from six months to a year.

Pocket type meter. Accurate to +/- 0.2pH. These are very reliable pocket type meters. All pH meters, including the ETI pH meter are delicate and should be handled with care.

Timers And Relays

One of the most common and serious problems experienced by growers is hydroponic lighting timer failures. Household timers purchased from major manufacturers are simply not designed to handle the (inductive) power loads of hydroponic lighting. Contactor relays are the answer. You can still use the standard timer, but power is routed through the contactor relay and not the timer. Alternatively, we also offer relays that have built-in timers. Timers will switch on your contactor and lights as and when required.

They are simple to use, as well as being very reliable. There's no wiring, just plug it in. Each contactor can handle up to 3 x 400W, 2 x 600W or 1 x 1000W lights. Four gang heavy duty timer contactors are also available which will switch up to 4 x 400W, 4 x 600W or 2 x 1000W lights.

Autonomous Environmental Control Systems - Fan Controllers

Autonomous Environmental Control Systems - Fan Controllers

The Sunbeam fan controller switches fans on when the room is too hot and switches fans off when the room is too cold. Intended for use with a simpler inlet or extraction fan. Temperature is set with the single rotary dial.

The Prima Controller - combined fan speed controller and thermostat which controls exhaust and intake fans. This can be wired to fans, program your requirements and it will do the rest. The Prima Controller has three analogue dials:

- one dial sets the best temperature for the controller to maintain
- one dial sets the minimum air flow for the inlet fan
- one dial sets the minimum air flow for the outlet fan

This ensures continuous air flow, regardless of temperature differences. Further information is available from the Data Sheet.

Prima Fan Controller - controls inlet and outlet fans, has variable pitch control and thermostat overide to control temp. of your grow room

Osmosis

In some parts of the UK, water quality is poor so it can be difficult to obtain optimum results expected from hydroponics. Reverse Osmosis (RO) is the answer. This is a water purifier which removes all unwanted residues and particles from your water, thereby giving the grower better quality water. These need to be ordered in advance so the exact model best suited to the type of water in the grower's area is supplied. However, chances are that most growers won't require one. If you are in any way unsure, please contact us, so that we can advise and order a unit for you.
