polyethylene hose running along the support wire to all towers. If you put
a ¾-inch tee on top of the ¾-inch PVC sleeve of each tower, you can run
the black poly line through these tees to support the poly line. Insert two
drip lines to the top pot and one halfway down the tower. This will assist in
distributing the solution evenly down the plant towers (Figure 7.19). Each
plant tower requires 10 square feet of floor area to permit adequate light
penetration to the crop.
These towers are very productive (Figure 7.20). One tower of eight
pots will produce 32 heads of lettuce or bok choy monthly if you start the
seedlings in rockwool or Oasis cubes, then transplant them into the plant
tower at 26 to 28 days as they take about 60 days from seed to maturity
(Figure 7.21). Sequence the planting so that you may harvest every day or
so depending upon your personal needs. Herbs will take several months to
become well established (Figure 7.20). After that you may cut them daily,
as a little trimming each day is better for their continued production than
