Description
SUStee is the first moisture tester with a pF value indicator (available water capacity).
The roots’ ability to absorb water — or the plant’s “thirst” — becomes visible.
There is a range of pF values suitable for all plants (the “ideal moisture level”). SUStee is designed to start changing color from white to blue at the midpoint of this ideal moisture range. In this way, the ideal moisture level for each plant can be monitored according to each type of plant and soil.
