C21H30O2 said:depends on your style of grow and your veg time. you could do sog and put 4+ plants per sqft or you could grow scrog and only grow 4 under the entire light or you could grow regular (no training) and then it would all depend on your veg time. your most effeceitn setup (yeild wise) will most likly be a SOG or SCROG as the 600 doesnt have as great of light penetration that the 1000 has.
