Best way to handle runoff from gritty mix?
My office at work has the standard complement of indoor plants - tropicals and ficus - currently planted in tiny pots filled with moisture-retentive potting soil.
We're moving to a new office in a few weeks - one with much more light - and I thought I might as well repot into bigger pots and better soils in the process.
The gritty mix seemed like the best choice to me - almost impossible to overwater and stable for a few years.
But with such a fast-draining soil, how do I handle the runoff from the bottom of the pot?
If I'm watering as I should - not in sips, but infrequent, deep watering - there will be more runoff than even a deep saucer below the pot can handle, right? At home I could probably move the pots to the bathtub and water there. At an office, that isn't an option.
Any suggestion for a setup that helps deal with this issue?
Should I try to find a deep trough to put below the office plants to catch water? Look for saucers that also include a spigot?
Creative ideas welcome.
