Propagator 37 x 31 cm

Propagator 37 x 31 cm – room to propagate a full tray at once
When a handful of plugs isn't enough, you need a propagator that keeps up. The Propagator 37 x 31 cm gives you the space for a complete propagation tray under one ventilated lid, maintaining the warm, humid conditions that cuttings and seeds need. Explore all our supplies in the cloning and propagation category.
Fits a full propagation tray
At 37 x 31 cm, this propagator comfortably holds a Grodan 77 Plugs sheet or a Root Riot Tray 77. That means you can run a complete batch of cuttings in a single propagator rather than juggling multiple small containers.
Gradual ventilation control
The lid has a rotary vent for adjusting airflow. Keep it closed initially for peak humidity, then open it step by step as roots form. This gradual acclimatisation reduces transplant shock and prepares young plants for life outside the propagator.
Stepping up from the compact model
If the Propagator 24 x 21 cm no longer meets your needs, this larger version offers substantially more growing area while still fitting on a table, shelf, or under a grow light.

Will a Grodan 77 propagation sheet fit inside the 37 x 31 cm propagator?
Yes, the Grodan 77 sheet fits well inside this propagator. Always double-check the exact tray dimensions, as some sheets may need minor trimming at the edges. The Root Riot Tray 77 generally fits without modification as well.
What is the difference between the 24 x 21 cm and 37 x 31 cm propagators?
Size is the main difference. The 37 x 31 cm model holds a full propagation tray, while the 24 x 21 cm version suits a handful of loose plugs. Both feature adjustable ventilation and a clear lid for light transmission.
Can I use a heat mat underneath this propagator?
Yes, placing a heat mat under the propagator adds bottom warmth that speeds up root development. This is especially helpful in cooler rooms or during winter months. The propagator itself retains humidity, while the heat mat provides consistent warmth.
