From seed to harvest involves two phases: 1. Germination (from seed to seedling) 2. Days to harvest which is from seedling to harvest. For your seeds to germinate you need proper germination temperatures and some water (and sunlight). The germination temperature and days to germinate varies by variety -- watermelon seeds tend to like VERY warm temps for germination with germination in about 3 days at 30c and about 10 days at 20c. I would factor about 14 days for germination as a general rule of thumb. Days to harvest varies by variety with smaller varieties taking about 60 days and larger varieties taking closer to 90 days. ‘Charleston Gray’ harvests in 85 days, while Little Darling takes 65 to 70 days, Carolina Cross takes 100 days. I think most varieties fall into the 80-90 day category. Overall, I would allow 114 days, provided the conditions are GOOD (close to optimal) for watermelon from seed for most varieties -- and about 85 days for the smaller (smallest varieties) and you're looking at about 120 days for the really LARGE watermelons.
