Carrots will need to be grown in a media bed of at
least 30 cm (12”) deep. The species of carrot used
should be one that is shorter, stockier. We recommend
Natches as an excellent flavored carrot that is easily
grown in hydroponics.
The carrots will press against the media as they grow,
and to some degree, pick up the surface texture of the
media. So it is best to use a fine media such as sand
and avoid coarse media such as pebbles.
A full bed of carrots can be thinned out all winter. Although
the carrots will grow very slowly, if at all, they
will usually have enough sun to survive.
Pests: Aphids, carrot rust flies, carrot weevil, and cutworms.
Diseases: Leaf blight
Harvest: Start harvesting when they reach the size
diameter you like. Reseed in the area you are harvesting,
or plant another type of crop.
