Nutrient Management

An essential bit of kit for any hydroponic grower, this robust EC meter is designed to suit anyone working to a budget without compromising on reliability. Microprocessor controlled for fast efficient readings, the meter also has a few handy extras including a hold function to assist reading and recording of levels, an auto shutoff feature that cuts in after ten minutes of inactivity and a built i...

The Horticare EC pens are a good quality measuring instrument with the following features: Auto shut-off – conserving battery life, Drop shock up to six feet - reinforced probe much more robust, Water resistant – drop these in your tank; they will float and survive, In use these pens are user-friendly and reliable, if they are well looked after and maintained they will last well b...

Sturdy, reliable nutrient meters from Bluelab Hydroponics in New Zealand (formerly NZ Hydroponics). The Bluelab CF Truncheon measures EC, CF and TDS, is temperature compensated and completely waterproof. These meters tend to go on forever, just make sure they're checked in Conductivity Standard (see related items below) and cleaned at least once a month otherwise they'll under-read. To make carin...

Combination PH and EC meter from market leaders Bluelab of New Zealand (formerly New Zealand Hydroponics). Supplied as standard with a whopping great five year guarantee, these sturdy little meters were first marketed at commercial growers but have rapidly gained popularity in the hobby market due to their robust design and highly reliable performance. As you can see from the picture the PH and EC...

The Bluelab Guardian Monitor measures all three critical parameters to successful growth: pH, conductivity and temperature. As the environmental factors such as sunlight hours, wind, inherent plant growth change so do the plants uptake and need of water and specific nutrient elements. The Guardian is a constant indicator of the changing desired levels of pH, EC and temperature by the plant through...

Probably the most effective and in the long run cheapest way of keeping your nutrient pathogen free and fully aerated. The unit needs to be used in conjunction with an air pump. The new Aquazone Ozone Generator provides ozone directly into the nutrient solution at a safe level for the plant roots and nutrient mineral elements but deadly level to any pathogens present. Many root disease are opport...

Lowers the pH of hydroponic nutrient solutions. Contains 81% phosphoric acid....

pH down solution for use in the early stages of plant growth - as opposed to the normal type of PH down sold for use in hydroponic systems that contain 81% phosphoric acid, this product contains 38% nitric acid. This makes it especially suitable for use with grow nutrients in very hard water areas, it will have less effect on the overall NPK of the solution when added in relatively large amounts. ...

ATA Clean is a cleaning agent for all types of irrigation systems - it prevents and removes calcium, iron phosphate and algae mineral deposits in irrigation lines, on pumps and in nutrient tanks. Suitable for use in all types of irrigations systems and growing mediums (hydro, coco, soil), it has no effect on the plants being grown. ATA clean should added to your nutrient solution at a rate of 10ml...

Fully submersible, shatter proof and extremely reliable nutrient solution heaters from German manufacturers Eheim. Drop them, have them half in half out of the water and they will not break. Features auto safety shut-off, accurate temperature control and a 1.7 metre power cable. Probably the best suited tank heater on the market for hydroponic use, and great value for money as well....

These liquid pH testers are a very economical way to monitor the pH level of your nutrient solution. Each kit consists of 20ml of reagent, a small phial and a colour chart to translate your result into a pH value. Two pH ranges are available: 6.0 - 7.6 and 4 - 10. Whilst these kits may not be sufficient for the more experienced grower demanding a very accurate pH reading, they do provide enough i...
