Benzelsanswered grow question 3 years ago Id go one plant per sq ft max, so 9 plants, as more pots/plants just = more work and more probs and expenses. Each seed costs how much again? Plus cost of pots and media, If u can get away with less plants for same yield then do so- makes life easier not having to buy and germinate 12 seeds each grow. Man that would get expensive fast huh?
