With warm water (70F-82F, optimum 77F), good water quality, and good feeding you might get pumpkinseeds to large enough sizes to spawn this summer at one yr old. Fast growing ones are reported to mature at age one in OH & IA. Males at 2.75" were found to be mature at one yr old. They often spawn 3 weeks earlier than BG. Nest diameters are 3.5 times the length of the male.
