View Full Version : Help with Lighting System Purchase/Wattage

I am looking at purchasing a lighting system for my indoor plants. I have heard that 50-60w of HID lighting is ideal per square foot, I have also heard that 30w will do just fine. How much light should give my plants?

:) 40-60wpsf is good. But, if your plants tend to stretch or you really want aggressive growth and production then you may want to consider 50-70 wpsf.
