100Pcs Grape Seeds

Sow Seeds: At the end of that time period, open the container and plant the seeds at a depth about three times their length in a flat of damp and seed-starting mix. Ensure the flat has bottom drainage holes, and space the seeds 1 1/2 inches apart from each other. Place the flat under a grow light that runs for 16 hours per day because grape seeds germinate best under long-day conditions, and keep the seed-starting mix damp. If the temperature is kept at about 70 F during the day, it is best to lower it to 60 F at night. In this growing environment, grape seeds can grow quickly.
