Chrysanthemum Hydroponics

Osmosis


Seedlings for the 2012 season

In very simple and practical terms, in relation to plants, osmosis is the transfer of water (and nutrients) through roots into the plant. In some extreme cases it is possible for the reverse to take place.

I will not go into all the technical reasons for this, it is sufficient for us growers to know the principles. Other factors are involved but do not require discussion at this stage.

Water (with nutrients) with a lower electrical conductivity (EC) will transfer into plants that have a higher EC. See Section on ELECTRICAL CONDUCTIVITY. Or the reverse in extreme circumstances.

In practical terms, if the plant is active and growing well and has a good EC, water (with nutrients) and lower EC, will pass into the plant giving conditions for continued active growth.

The principle of controlled nutrition must be applied with regard to age, phase and pattern of growth, flowering etc., see further information under NUTRITION.

In extreme cases mentioned above, when the EC of the water (with nutrients) is too high then water can actually pass from the plant causing dehydration and wilting. Growers may notice at times when this occurs the aggregate may still be wet. At flowering time the petals may scorch and lose texture and lasting qualities-overfeeding!

Many experienced growers can actually "read" their plants and can adjust the feeding programme accordingly.

Hydroponic growers can measure and monitor the EC of fertilised water accurately, combined with "reading" the plants and observation, these factors are very advantageous in producing super blooms.
