Anyone have a formula for....

[tha del sound]

sounds like an easier version of lst. just tilting instead of tying down.

Holy shit that is a nice plant! And yeah after much careful thought, I have decided there is no formula, to may other factors to consider wear and tear on the bulb, shading, reflection, ect. I'm just gonna say uck it, and supplement lighting at different distances with CFL's.
I like the light meter/ temp gun idea, that would definately get great results!

Well X-Crispi and I both do it with our plants....you can get a $20 temp gun on e-bay or wherever.....works great. :thumbsup:

not a bad yield for an indoor plant but have heard of beter (outdoors)

doubling the distance should have the same efect of using a light that is equivelent of square ruting the lumens of your origional light eg. a light whitch produces 9 lumens is shining on some paper 1cm away from it and the lumens reatching the paper is X if the distance was doubled then i would asume that the light reatching the paper would be the square rute of X

ps. not sure if corect but my comon sense sujests it probably is.

Dave.....let me make clear that X-C and I just do the temp gun part....not the light meter part. The light meter thing was info given to me....not something I use but the temp gun is.

Sorry to hijack....I tried to rep reaper but can't......GREAT plant!!!:thumbsup:

When I take my light meter and measure sunlight intensity at noon on a clear summer day-----around 10,000 fc (footcandles). That's true wheather standing atop a tall building or on the ground.

18" directly below my hortilux 1K hps is also 10,000 fc------now another 18" farther below is only around 2500 fc-------yep about 1/4 from the previous point of measurement.

And yes Virginia----I've found that plant material exposed to intensities much higher than 10K fc start bleaching-------and not from heat.

So what this means to me is-------we have a very small envelope of useable light intensity from HID lighting.

Things to do:
1) keep your canopy flat or concave with tying branching down, trellising, or whatever.
2)light movers are great----- especially in the aero/hydro world where moving plants around is not practical.

Damn, that makes it sound only practical to have plants up to about 2.5 feet tall. That means my dreams of having 8 foot + tall plants is gonna require a ton of supplemental lighting on the lower branches to get em' big without sacrificing quality.
Back to the drawing board, and I gotta pick up a ton more flouros than I hoped. Fuck it, good things require the extra effort!
