Sweet delicious carrots can only be achieved by growing your own. Approximately 620 seeds/gram
Hints:

Soil should be worked 15 to 25 cm [6-8"] deep.

Avoid fresh manure which may cause forks, splits and tough hairy roots.

Sow seed at a rate of 2-3 per 2 cm about 1 cm deep.

Carrot seeds need to stay damp until sprouted.

Sprouts will NOT push through crusted soil.

Harvest after carrots have a good orange colour when flavour is best.
