of what it calls AeroFlo
2
20, a 20-site system, as shown in Figure 6.27. It
includes an 8-gallon reservoir, two 6-foot grow chambers, a pump, piping,
support structure, 3-inch mesh pots, and coco coir or GroRox clay pellets
(Figure 6.28). The grow chambers are approximately 6 × 6 inches so they
hold up to 4 gallons of nutrient solution each making the total capacity of
solution 16 gallons with the drain overflow tubes set at their high position.
If the tubes are set all the way down to the base of the grow chamber, then
all the solution will be retained by the reservoir only to give a total of 8
gallons. This gives the system the capability to function as deep flow with
the drain tubes set high and as an NFT system with the tubes set low to the
bottom of the grow chambers. They suggest using the high position when
transplanting and lowering the solution level to an NFT system once the
plant roots emerge into the grow chamber. The suggested retail price of
this unit is $350.
The AeroFlo
2
30 site system differs from the smaller 20 unit in that it
has three 6-foot grow chambers with a 20-gallon reservoir and uses thirty
3-inch mesh pots for the plants (Figure 6.29). The total reservoir capacity
in the flooded stage (overflow tubes set high) is approximately 34 gallons.
The model 60-site system having six grow chambers may be configured
