A very experience grower visited me the other day and recommended 2 changes to my growing technique. One was the use of MSU fertilizer to the RO water. No brainer, I knew it for a long time, just too lazy to switch, I ordered a bag today. The other recommendation was the use of a whetting agent. We pulled a large Pescatore growing in Sphagnum moss apart and sure enough the middle of it was dry. I thought I was watering it sufficiently but was in fact not. Aqua-Gro at 50 to 110ppm added to the fertilizer was recommended.
MSU has been discussed to the Ying-Yang, any comments on the use of a whetting agent?
