well to start whatever the size when you start flower. It will be double that at harvest. So if you have 3 feet of height then flower your plant when it is around a foot and a half tall. maybe 4 plants i am ambicous so i would try 6.:thumbsup: depend what strain and such.
bobjob4u Reviewed by bobjob4u on . How many plants... It may have been asked and I just cant find the answer, but how many plants can one finish under a 400w HPS. The grow space would be 3x3.5 ft. And could I use SOG in this small space? What about height, when should they be forced to flower? Im losing my mind here... :i feel stupid: Rating: 5
