Propagators - Hardening off - Paul Fowler
SECTION 3 - HARDENING OFF
PROPAGATORS
For roots to develop it is important that the temperature and humidity are correct. The best way of providing the right conditions is to keep the seedlings/cuttings in a small enclosed space.

You can construct a simple home-made propagator, but as commercial propagators are inexpensive and widely available, these are recommended.

Propagators come in various sizes and are available heated or unheated. In the average indoor grow-room an unheated propagator is adequate, but if the grow-room gets cold, then it is best to get the heated type. The size of the propagator you get will depend on the amount of room you have and the number of plants you wish to grow.

If you are using a heated propagator it should be lined with a thin (3 mm) layer of a loose and nonI absorbent medium (such as perlite), which will retain moisture and prevent the rooting medium drying out.

ONCE YOUR PLANTS ARE IN THE PROPAGATOR.

For the first couple of days the air vents should be fully closed. Open the vents slightly each day, so that by the end of the first week they are fully open. After two weeks, or once roots have developed, the top cover should be completely removed.
