My seedling was put in to a small SIP from a regular solo cup- and it took 24 hrs. to start wicking from the rez..Very little was taken up by the soil overnight
It uses kite strings, instead of a wicking foot, but I think the principle is the same.?
I marked the water level on the rez, and it didn't drop at all until the second day .
The soil was just damp when I started it 3 days ago- now it's hydrated like sip soil should be..not too wet, not too dry...
