Propagators

Propagators for cuttings and seedlings

A propagator's job is holding warmth and humidity around fragile roots until they're established — get either wrong and cuttings sulk or seedlings damp off. We stock unheated propagators from windowsill size up to XL: the Medium Propagator (38cm x 22cm, £6.95) and Large Propagator (52cm x 37cm, £13.95) suit a modest batch of clones, while the Large Budget Propagator (£6.95) covers a bigger tray for less outlay.

For consistent warmth through a cold room or winter propagation, a heated option makes the difference — the Stewarts Medium Heated Propagator (38cm, £28.95) holds a steady base temperature rather than relying on ambient room heat, which matters if your propagation space sits below 20°C overnight. Pair any propagator with a propagation heat mat underneath rather than inside the dome — the mat warms the medium, the dome holds the humidity, and the two jobs shouldn't be combined in one unit.

Vents and domes

High-dome lids give taller cuttings room to establish before they touch the lid, while adjustable vents let you dial humidity down gradually as roots develop — running fully sealed for two weeks straight is a common way to lose a batch to damping off.
