depends how big u want your plants. if you go with smaller plants-lets say clones 1 week veg-you could fit (25). in this scenario you give each plant 1 square foot of growing space. another option is to let your plant veg a little longer thus giving it more space. if a clone is vegged for a month it may need 2 feet squared growing space. this will redue the number of plants to (5) with some extra room. i suggest indica dominant strains for Sea of Green (SOG) or Bush of Green (BOG).
