ive been wondering all the seed banks yield goes by square meter. which is 3'x3' and i was reading an article that says you could have 4 or 5 plants about 3 to 4 feet tall in a sq/m. my grow space is just about a sq/m and i have 3 plants that are about 18 inches and they are starting to overlap. is this healthy to put 4 or 5 in a sq/m. or am i mistaking what a sq/m is.
