What is the effect of Fiba-Zorb
on the quantity of water absorbed?

Frequently asked questions are “Will my potting soil be too wet if I add a wetting agent?” and “What will be the effect on my substrates in the dormant or dark period of the year when there is little evaporation and growth activity”.
 

It is important for the grower to know that the wetting agent that he uses ensures growing media does not hold more water than it would without the wetting agent and preferably a little less.​

 

The PBG in Naaldwijk made the following observation

 

“For white peat addition of Fiba-Zorb improved the air content (AFP) in the whole measurement range for the Naaldwijk method.”

 

The following research was undertaken by PBG in Naaldwijk, Holland in 2000.

 

From this research we learned that Fiba-Zorb not only ensures that the substrate shows a much improved wetting speed and volume of water uptake but equally important to the grower is the fact that during the dormant or dark period the substrate treated with Fiba-Zorb actually improved the drainage and slightly reduced the amount of water in the substrate, as seen in the PBG graphs above for black and white peat compared to the untreated sample.
