Good question Joseph. For your conditions, I’d suggest Longe-7H — it’s a hybrid but matures in 110-115 days and yields 40% more than Longe-5 on the same fertilizer. Seed cost is ~3x but the yield difference pays it back easily in one season.
If hybrid is truly out of reach, Bazooka open-pollinated matures in 115-120 days and is widely available. Worth a try.
