Big jobs require a big Truncheon! With a conductivity range right up to 6.0EC (60CF or 4200ppm), it will never leave you short. The Commercial Truncheon® Nutrient Meter has been designed for hydroponic crops that require a higher than normal EC or CF requirement during their growing cycle. It’s super tough, fully waterproof, has no on/off buttons to worry about and does not need calibrating. It’s great for stirring your nutrient tank too!

It is essential when growing with a hydroponic solution to KNOW what the strength of the solution is before feeding your plants AND while they are growing. This is easy when you use the Commercial Truncheon! To take a reading of your solution – simply place the probe head into the solution for 1-2 minutes to reach the same temperature of your nutrient. Remove from the solution and place back in to take the reading as indicated by the flashing lights. Rinse the probe after use in fresh water and clean once a month to ensure the Commercial Truncheon Nutrient Meter remains accurate.

• Fully waterproof
• No calibration required
• Auto sense on and off
• No external switches or adjustable buttons
• Battery life minimum 1 year (or shelf life of battery)

These pH adjusting crystals will, once and for all, eliminate the hassles and worries of spilling, splashing and dealing with harsh liquid pH adjusters. Use to adjust the pH of fertilizer and plant micronutrient foliar solutions.

pH adjusting crystals that will, once and for all, eliminate the hassles and worries of spilling, splashing and dealing with harsh liquid pH adjusters. Use to adjust the pH of fertilizer and foliar spray solution for vastly improved nutrient availability with the extra inclusive bonus element of chelation for even better plant health. Proper pH is vital for healthy plant life.

To maximize plant growth, the pH content of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5. Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because our formulas are pH buffered. However, some important exceptions do exist. Acid content can reach unacceptable levels when nutrient solutions are mixed with poor quality water, or pH unstable media – such as rock wool and gravel products – are used, and when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop.

pH Down: Acid formulated using food grade Phosphoric acid. Just add a little at a time if your nutrient pH is too high in order to lower the pH to the proper level
