Hi. Whats the setup of your semi hydro? Clear plastic? Holes only at the sides? Bottom? Medium used?
I have several medium in different containers, one has pure pumice, the others has combination of pumice and LECA...
We usually use clear plastic container, for easier detection of roots and water level. We only refill when the water is dried up. And let it stay dried for a day. And refill. But sometime we refill when its at its lowest level.
What about others?
