I started with 8 plants in about a 4 x 6 space and a 1kwatt light. By the end of the grow I had five females which took up every single inch and needed more. Working around them became really hard; the branches got bumped and broken, and trying to do maintenance on them became an extreme hassle. Make sure you leave enough space at the beginiing if you can't move things around later. My plants got to be close to five feet high by the end and about 2-3 feet wide apart. They GROW.
Weedhound Reviewed by Weedhound on . How many plants under a 1000W(HPS) to maximize the yield? Hello guys, I wanted to get your opinion on how many plants to put under a 1000W (HPS) to maximize the yield? A 1000W covers a 5X5 space right? I do not want to use the SOG technique cause it too much work and Iā??d ratter be caught with fewer plants if something goes bad ... I heard it didnā??t increase the yield anyways ! I was thinking about 16 plants (How tall should they be before the swich to 12/12) OR 25 plants (How tall should they be before the swich to 12/12) Rating: 5
