Optimal setup of light per s/f....

[midnightoker]

Everyone says get the light at close as possible without actually burning...

problem is as you get closer, you lose coverage (light reach).... So the question is, what is the optimal height to sufficiently cover a given space?

say a 4x4 space with a 600w hps....

the light will draw a horizontal line (light/shade) across the wall of ur room. move the light up or down so the line's right above the top edge of the canopy

The method seems flawed as it would all be dependent on the dimensions of the room itself, not necessarily the grow space... ...

the question really is, how many plants are you trying to cover with a 600hps?? because the ones that receive that extra coverage when you lower them will produce thicker colas, so its up to you if you rather leave it higher up to get more even buds, or focus on the big boys

Here's an interesting chart dude. Compares the Sun to our indoor lighting (lumens).

Hope it helps... Cheers!

definitely more in line with what I'm looking for....

did I miss it...seems to really address the footprint s/f...not necessarily the height of the lamp, or better said, the distance of the lamp from the ground/footprint....

I believe the chart addresses what is important... the ideal distance of the light to the canopy (not the ground)... not necessarilly the sq ft of coverage of a given wattage lamp. There are other charts addressing this and I believe Subcool has a good rule of thumb in one his posts.

I run a room with 600's and another room with 1000's. I keep my 600's about 20" away... two of them easily covers an 8'x4' area. The 1000's easily cover a 5'x5' area at 28" (the distance from canopy I use). I am very happy with the end results... as are the collective members.

Cheers.
