The Clever Pots Propagator Base works with the Clever Pots Propagator Lid (sold separately) to create the ideal environment for growing seeds into healthy seedlings and offers a simple way to water and maintain young plants. You can pour water directly into the base of the propagator underneath the seedlings without removing the lid, encouraging healthy root growth and preventing the trapping of fragile stems between the lid and base. The base is translucent so that the water level can be easily monitored, preventing over or under-watering. Fits all standard plug trays. It is made from flexible PP plastic, reducing the risk of cracking and frost damage, designed to be used across multiple seasons. Colour: Black/Dark Grey. Dimensions: D 44.6 x W 25.5 x H 6.2cm. Material: PP - Polypropylene.
