I am planning on growing 8 plants in a 5' x 8' closet with good ventilation. How many High Pressure sodium lights will i need. I am planning on getting a 1000 watt fixture. Thanks- the begginer
the question doesnt make much sense because you pretty much answered it. if you do some readin, you will see that 1 1000 watt bulb w/ballast will more than satisfy your needs
