Wattage or Lumens

Haha, sorry. To be honest, I should probably smoke a bit more in the mornings before posting.

i have clamped my pc at 1100watts rms, The power supply is rated at 1500w peak. An LCD screen uses way way less power than old school radiated tubes.

This is very important (and smart). What he's saying is... there is more involved with light than just measuring Watts or lumens. This is one of the most important concepts to understand.

Distance is also critical. The closer the bulb is to the plant, the more light the plant will receive. It's really quite shocking when you find out how much light is lost each foot of distance. So what's this all mean? Basically a 600W lamp right on top of the plants is better than a 1000W far away. This is why I run air cooled lights. It lets me put the light right on top of the canopy without burning the plants.

Color spectrum is also critical. In theory you could use a 1000W green bulb but the plant would grow very slow, if at all. That's why you can get away with just red and blue LEDs. UV is also said to have a factor in THC production. Many swear that UV rays increase potency.

Let's talk light and grams per watt... I personally don't give a fuck about grams per watt. Let me explain. Here in the NW each 1000W light costs $27 dollars a month to run 12/12. When I was running two 1000W lights I'd pull a pound per system for a total of around 3lbs. When I added another light it went up to 20oz per rack. Now granted adding that extra light reduced my grams-per-watt but in increased my harvest 4oz. per rack or 12oz. total. So if an additional 12oz of herb costs me a whopping $60 who cares if it fucks up my grams-per-watt. Does that make sense?

Numbers will fuck with you! Measurements will fuck with you! People that measure things too much are called measurebators. Don't be a measurebator...
