(600 * (6/8)) + (400 * (2/8)) = 550 watts to use in the denominator.
Yeah bro, lemme see a pic or two of them in action - I assume you got the fossilized leaves off of the tray? :)
FYI, might have another shipment for you soon - thinking of converting everything in my room over to aero, which means I'd have another 2x4 for you and another 50ish gallons of hydroton - also, there's still that 4x4 table if you want it and a shitload of pumps and other miscellaneous shit - I'll take a full inventory in a few weeks when I'll (hopefully) finally be done with this buildout.
just look at the f'in #s then if u want a mathematical solution. you shrink your foot print by dropping the light and wattage. just numbers, not the right ones, but will make the point. lets just say that you loose 10% light intensity every 6 inches (despite a 400 at 6 inches really doesn't have that large a foot print, prolly 2/3 what the 600 would have at the same height but once u raise the 600 it is about 2 times larger.) now back to the light loss. 10% x (18 / 6) x 600= 180 watts lost. 10% x (6/6) x 400 = 40 watts lost. now with those losses bumps the 600 --> 420 and your 400 -->360. frankly to up you gpw you would be better off with the larger canopy under the 600 with ventilation so you can drop it 8-12 inches over the tops.
now that above is assuming the light looses intensity at a constant over 6 inches, that is an assumption that light doesnt slow down faster after it travels for a short ammount, u can correct if you actually know.
generally, i'd rather look through the archives.
nevertheless, i needed some specific info... which i got.
i will always love how those of you who regurgitate bullshit you read on the web, & re-hash shit you've read in forums, offer up advice.
did i ask for opinion on my light set up?
who said i was comparing my garden to your "garden" ?
* brand new lab , first run , SOG (lillipops) ...using the light set up i noted is giving me 8oz of dry dank (in this case Sour D) from 24 cuts... every three weeks.
.4 grams per watt
i can do better for sure.
before i built my new lab and changed my grow style, i was in the .7 gpw range.
too, for all you opinated "farmers", is par from a 600w light at 18" from the canopy the same as par from a 400w light at 6 inches?
you have been reading up on lighting right?
semi respectfully, i wanted a mathematical answer... not your fu*king opinion on what i should do with my light set up, your thoughts about gpw & its correlation to measuring yeild, or anything else.
i appreciate input when directed properly & i respect all remotely valid answers.
also, get a clue, it's not like the lights are fixed.
i, unlike many of you and because my space is large enough, will experiment & find out what works for me.
9 mother plants producing cuts that give me 8 oz every three weeks ...of super dank ...for one person.
i, and this FAT bowl of smokables next to my keyboard, would call my new opperation a straight up success.
motherload ===> duely noted ====> there is room for optimization.
** bobby smith : thanks again for the hook up !!! : making great use of all those goodies!
wow - well i gave you a mathematical answer and an opinion - sorry
I do not read shit and spew out the same shit
I have been growing indoors since 84 and have used every fucking light made with the exception of 1500 watters
I will stay out of your threads from here on out!
Peace
