I germed in a plastic cup, transplanted later to a 6" pot and, just today, transplanted to a 3 gallon. Each time I've transplanted, I've lost about 1/2" of height - it's been buried in the soil. I've got about 7 inches above soil now in the 3 gallons. I'm not seeing any signs of sex yet. Is it ok to start flowering? Will I be able to determine sex once I start flowering? Thanks.
