At the Greenhouse we use Aeroponic units for plant propogating. Areoponic units work by fogging, misting or spraying fertilized water on plant cuttings to promote rapid root growth. The combination of warm, fertilized and highly, oxygenated water produces roots much faster then standard Hydroponic units.

These units can be very expensive to buy from a retailer, but luckly they are easy enough to build yourself!

We have seen fantasic results with our DIY unit, it generally produces roots in half the time our standard Hydroponic unit does.
