Comprehensive instructions about how to take cuttings can be found in various places on the internet. Here is a short guide: Place the tray of rockwell plugs into the bottom of a propagator. Choose healthy shoots with thick stems from which to take your cuttings and make the last cut with a sterile scalpel. Dip the cut end into a rooting gel such as Clonex and then place the end of the cutting into one of the rooting plugs. When you have finished taking your cuttings, put the lid on your propagator and move to a mild environment a few inches underneath a grow-lamp. Keep the rooting plugs moist and mist your cuttings 2-3 times a day. After a few days, when roots begin to appear on the outside of the cubes, open up the ventilation slots on the lid of your propagator to reduce humidity. When your cuttings have completely rooted through the plugs, they can then be placed in a larger rockwool cube, soil or a horticulture system to grow onwards. Dimensions: 530mm long x 310mm wide
