Flood table inlays
To irrigate cuttings and scions in small pots regularily and basicly constantly flood table inlays are useful things.
Actually these flood table inlays are rather a very shallow tub. It gets flooded, when the plants have to be irrigated. And while the water slowly runs back out again, all cuttings will be supplied with the same amount of water. You can regulate the watering cycles of flood table inlays with clock timers.
