10 cfls -20...The more coverage the better growth..but 10 X 100w isn't the same as a more HID set-up 1000w, they max out at a certain spectrum lumen..If you have a 6500k mh, can't get that power with X amount of cfl

I would like to hear from the other people on the site.

Topic: lumens

Argument one: Lumens can be added to be divided by the square feet of a room to get the total lumens per square foot. This is also known as the "inverse square law" in which intensity=light output divided by the square feet. This is especially essential to all growers. For the growers who grow with CFLs you will always have more than one bulb (unlike MH/HPS growers) so you will always have to add all of your bulbs lumens together in order to solve for the equation.

Argument 2: You don't increase your lumen output by adding more bulbs together. The highest rated lumen bulb is the absolute max that you will get. YOU CANNOT ADD LUMENS TOGETHER. Having 5-1700 lumens bulbs in different areas of your plant is great but having them side by side does not affect lumen value. So whether you have 5 or 50-1700 lumen bulbs, the most lumens your plant will see is 1700. Want more lumens? Buy one lamp that produces ALOT, plain and simple.

Both 1 and 2 are true----simple as that !!!:mrgreen:

either way lumen is just a word humans use to measure how we perceive light. It really doesnt have anything to do with plant growth.

plants see 350-800nm. people see 350-800nm. people are tweaked for a more narrow range, (the green range) But shit! man I can still see the blue and red too. can't you? Saying lumens or lux is monochromatic reading is just silly.

pretty close. people are tweaked for a single range, green, as that is the color of most of our food sources. plants have a dual peaks in the read and blue ranges
