I do 15 plants per 1000 watt if they are growing large, or 30 plants per 1000 watt if they are planter box style single colas. I now use 600 digitals instead; growth seems to be about the same as regular 1000 watts, but less energy and significently less heat. Penetration seems just about as good too. Cant imagine 750 digitals or higher.
Racerx Reviewed by Racerx 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
