In a root system that functions well, roots die and new roots are formed. The remains of roots that died form an ideal growing substrate for pathogenic organisms. After the pathogenic moulds have multiplied in the dead root material, they are a threat to the healthy roots. These are easily affected, and will lose an important part of their function. This causes stress to the entire plant and stunts any new growth.
Featuring excellent sound deadening properties, Rhino Acoustic Ducting dramatically reduces fan noise and the sound of air travelling through the ducting.Acoustic Ducting is used to reduce the noise made by ventilation fans in growrooms and industrial areas.It's made from a perforated inner core that's identical to our Standard Ducting but with lots of small holes punched in it - this is then wrapped in a layer of glass-fibre and sealed by another layer of aluminium foil. As the air travels down the inner core the sound is let out through the holes into the glass-fibre, which deadens the sound.In practice it reduces the noise of a fan by around 60%-80%, and is almost always used with fans of 150mm and above although all sizes of fans benefit from it's use.Very highly recommended -
The instrument is only as accurate as the probe is
Probe cleaning is one of the most important parts of owning or operating any Bluelab meter, monitor or controller.
If the probe is contaminated or dirty, it affects the accuracy of the reading displayed. pH probes are scientific instruments and should be cleaned and calibrated regularly to extend their life.
The probe surface is where the instrument takes the reading of the solution. The information is sent back from the probe to the electronic brain of the instrument. A calculation is then done in the instrument’s brain or micro-computer and a reading is then displayed. If the information sent back from the probe is inaccurate due to probe surface contamination then the reading will be inaccurate. Cleaning your pH probe is a very easy task which will prolong your probe’s life.
