Medium Heated Propagator for propagating cuttings. Heated propagators are used when the room you are using is too cold, say under 15 degrees celsius. If you are in a centrally heated house and your room is always above or around 15 degrees you do not really need a heated propagator you would be fine with an unheated one. Heated propagators work by way of a thermostat that engages and disengages a small heater in the tray to maintain an ideal cuttings environment. Heated Propagators are available in three variations, medium, large and large variable. The medium and large standard versions have a thermostat that is set to a single temperature whereas the large variable model lets you set the propagator to any temperature you desire giving you full control over your cuttings process. The Medium Heated Propagator will fit: 28 x 36mm rockwool cubes, Jiffy plugs, RootIt cubes or 50 x 25mm rockwool blocks
