Cucumbers date back as far as 3000 years in India and China. Today they are a popular addition to almost any home garden. Approximately 35 seeds / gram.
Hints:

Seeding - Soil temperature should be at least 20°C. Cucumber seed will not germinate below 10°C.

Cucumber plants can also be transplanted. Peat pods are recommended.

Sow in clumps, 5-6 per clump, 1 cm deep with clumps 1 m apart. Thin to one or two of the best plants per clump.

Sow in rows, seed 5 cm apart, 1 cm deep. Thin to 20 cm apart. Pick daily once bearing begins to keep vines productive.

Morden Early - 50 days. Very early, producing clusters of medium sized dark green fruit which are tender and straight with a white spine. Compact and prolific. First fresh cucumber for slicing and pickling.
