South Carolina | Yes. This is higher than the recommended setting. When we drop the vacuum pressure we see the outer row units showing a decline in seed population perhaps from the middle units vacuum pressure being higher due to being closer to the fans and the outer units being a further distance from the fan. Not sure if this is correct but the 18-20 lb works for us. Seed size make a difference. Planting D&PL 1646. | |
