flowers - many of which have never been

propagated from cuttings before. Of course,

easily propagated plants will root quickly and

grow phenomenally in the RainForest. The

RainForest secret is the patented aero-

hydroponic method of delivering the nutrient

solution. Oxygen-charged nutrient solution is

sprayed through the air onto the cuttings, seeds,

and newly formed roots. This oxygen-rich nutrient

solution constantly circulates within the

RainForest reservoir, so that a lot more oxygen

reaches the root boundary zone than with other

hydroponic systems. The roots absorb optimal

levels of both oxygen and nutrients, so that the

entire plant thrives. The RainForest Model 36 is

at the cutting edge of technology with technical

features to satisfy professional growers and

scientific researchers, and a simplicity that

makes it ideal for hobbyists, as well.

Your RainForest Model 36 consists of the following components:

• Reservoir container with drain/level tube indicator

• Motorized spray pump

• Reservoir cover (with 6 plant sites)

• Six growing cups and cup lids

• Hydroton and polywool

• Flora Series Nutrient Kit
