Colin,

Are you looking to flower 10 plants at a time, or grow 10 plants at a time? See there are alot of variables here. Like I grow about a dozen at a time in various stages, and typically always have 4 in flower, its called a perpetual harvest. Or, you can just start 10, and then finish them off in the same space.

You let me know what your plan is, I can help you implement it. Also let me know your budget, that helps things too. What supplies, if any, do you already have?
