Aeroponic propagators are the fastest way to produce rooted cuttings for going into hydroponics. The idea is that cuttings are suspended above a tank of water and the solution is "sprayed" upwards by a pump and a special spray head. This method of constantly changing the water around the bottom of the cutting with fresh, highly oxygenated solution. Top Tip: add Silver Bullet Roots to the tank of your aeroponic propagator to keep the solution sterile and free of diseases. We also highly recommend the use of a product such as Dutch Pro Keep It Clean, House & Garden Drip Clean or Plant Magic Pure Clean to ensure that the spray nozzles do not become blocked which could compromise or ruin the rooting process.
