ok i love these threads....bottom line is if you have to ask others how to get three ounces from a plant then you dont have the skills yet to do it anyway....for 3 zips a plant you need a feel for growing pot you also need probly 1000w hps and veg for 6 weeks at least good soil good nutes......but like i said if you have to ask then your not going to be able to do it just grow some pot and get some experience and yield will come
