when to water/fertilize?

[kenr62]

I have been growing s/h on & off for 10 years or so with ok results - lots of healthy growth, few fatalities but not much flowering. I'm sure it's mostly my fault due to health problems and neglect.

I have searched and found lots of posts regarding the clear pots with holes. I have lots of those as well as net pots in cut off soda bottles etc. with holes.

My question is regarding the pots with no holes with an inner liner for the expanded clay pellets and a water level indicator. What is the ideal watering/fertilizing regimen for this type of system?

TIA,
Ken

My recommendation with those is to water with 125 ppm N fertilizer solution every other time, removing the basket and flushing it thoroughly the other two times before watering with plain water.

Unlike those with drainage holes, which really don't build up minerals if watered properly, the "no-drain" type will build up minerals rapidly if you don't flush them fairly frequently.

Another alternative - one I use on house plants in pots too big to flush regularly - is to feed 1 time out of 4, using plain water the rest of the time.
