Watering
Growers using passive hydroponic systems only have to water
by adding it to the reservoirs, to replenish water lost to evaporation
and transpiration.
Growers using active hydroponic systems, including drip emit-
ters, adjust the watering cycle so that the medium never loses its
moisture. Mediums for active systems are drained well so that the
roots come into contact with air. Each medium retains a different
volume of water. The plant's size and growth stage, the
temperature, and the humidity also affect the amount of water us-
ed. Cycles might start at once every six hours of light during the ear-
ly stages and increase as the plants require it.
Plants growing in soil or soiless mixes should be watered
before the soil dries out but only after the top layer has lost a bit of
its moisture. If the mixture is not soggy and drains well, over-
watering is not a problem. Excess moisture drains.
Plants have problems with some soils not because they are too

wet, but because the soils have too fine a texture and do not hold air
in pockets between the particles. As long as a medium allows both
air and water to penetrate, the roots will remain healthy. If the
roots do not have access to air, they grow weak and are attacked by
bacteria.
Plant leaves catch dust so it is a good idea to spray the plants
every 2-4 weeks with a fine spray, letting the water drip off the
leaves. Do this before the beginning of the light cycle so the leaves
dry off completely, and the glass of the lights is not hot in case
water touches it.
Some growers spray the leaves weekly with a dilute fertilizer
solution. The leaf has pores through which the nutrients can be ab-
sorbed and utilized. They claim that the growth rate is increased. In
various tests with legal plants, researchers have affirmed that plants
which are foliar-fed do grow faster.
Once the flowers start forming, the plants should not be
sprayed because the flowers are susceptible to mold and infections
which are promoted by excess humidity.
