seeds were sowed on (sterilized) quartz sand (1...2.5 mm) in pots (about
x 4.5 x 4.5 cm) soaked with water and vernalized at 4 =B0C under a plastic
for 2 days. The plastic wrap was removed 6 days after transfer to the
greenhouse. The light regime: 16 h light and 8 h darkness . The plants
fertilized with half concentrated sugar free Murashigge Skoog basal
5.8. The water level should be about 2 cm. Take care that the water is
up to the surface. No algae did grow under these conditions.
The growth is relatively slowly in comparison to soil grown plants.
after 4 weeks growth you get reasonable plants. They can be grown for
8 weeks but I did not investigate the longest possible growing time.
Notice, only half of the germinated plants will survive.
It is necessary to use the right size of sand. Fine sand is useless for
