Best layout for 3x600w?

Hello, i would like to ask what is the best layout for having 3x600w HPS hung vertically and 6-8 plants. Space is 7'x7'x7'. I was thinking something like that:

For that amount of square feet I'd go with 4 x 600 maybe using something like this:

xox
oxo
xox

The one in the center obviously would be the largest...

Well , since it`s never good to put plants in dead corners without lights OR walls and ceilings covered in reflectix/prodex/orca of choice and budget , Flat DOES have the best reason for putting 4-600`s in 49 sq ft to get as close to 50 watts per sq ft as possible , and that's a good start ....now...

I suggest 2 donuts with 4 plants around each of 2 stacked bulbs with 50/50 Sat/Ind hybrids like Arminius runs with his stacked setups....

Go read Arm`s thread and see how he does things ta give yas a better idea howta roll with your room.....

Good luck....DHF.....:ying:.....

Thanks a lot both of you for your answers! You give me some very nice ideas!

DHF, i know that 50w/sq ft is the recommended, but i have also seen you mentioning in another post that extra wattage is not worth it if you cannot have the optimum enviromental conditions. To put it in another way, since flowering of those 5-8 plants is going to be between end of March- end of May, i am under the impression that 4x600w would make my grow tent very hot. That's why i thought about 3x600w.

Your idea with the 2 donuts sounds good, that's another good alternative! Although, i have the feeling that the idea that flat suggested has less plants covered with more light (as each of the plants in that case gets illuminated by at least two light sources, aka 2x600w).

I am gonna use Orca for the walls of the grow tent when i get to the stage of flowering (2 months from now). So, in case i have 4x600w, i have 2 very good plans from you guys, one with the stacked bulbs by DHF, the other by flat9. In case i go with 3x600w due to heat, how would you do it? A/C is not an option unfortunately, that's why i am asking.

Well , I`m confused in that I thought it was a room and not a 7' tent , but still putting plants in dead corners is a proven no-no , even if it`s a perfect 4 plant 5 light setup in reverse where plants get light from more than 1 light source.....now....

When you saw me post about less than optimum wattage without adequate environmental control , it was about a lot more watts than you speak of Bro , and I used 3-600`s stacked in 6x6 inside dimension areas with air exchange twice per minute that took care of environment 10-11 months a yr , with a/c only needed in deep summer maybe couple months.....but....

If yas can`t provide a/c , get on the active intake and exhaust/scrubber combo train and ride that bitch with air exchange twice per minute and 1800 watts/36+/- per sq ft.....then....

IF yas can up it to 2400 watts with 2 donuts and 2 stacked bulbs with the RIGHT 50/50 hybrid , guaranteed 8 plants and 2 donuts will pull waaay more than 5 with extended veg time to come close to comparison.....now...

3 lights in any configuration other than side by side seems unlikely to work in said area without just putting plants on each side of the bulbs like Dabs is runnin in his setup.....and...as said earlier.....go look at Arminius` thread to gain perspective as well....anyways...

Thoughts to ponder , so good luck and.....

Peace....DHF....:ying:.....

Problem w/ two donuts is the space ... it's square.

Also, with respect to "plants in the corner," hmm.... let's take a look at that:

xox
oxo
xox

This does indeed have four plants in what you're calling the corners. But then look at the donut I think you're recommending:

x-x
-o-
x-x
x-x
-o-
x-x

This still has plants in the corners, no?

No plants in the corners Flat , and hey....Bro....You`re awesome for helpin and by no means am I cutting down your suggestions , so let my old ass try to explain further and maybe a diagram , but don`t hold me to it.....

With 2 donuts there`s light placement with 2 stacked bulbs in 2 spots @ 2'4" and 4'8" , and you`re right , it`s a tight space especially when it`s only lil bigger than what I stacked 3-600`s in 6' square , but what I`ve seen Arminius do with double stacked bulbs in tight quarters is proof positive with the right strain/hybrid , the yield potential is there.....IOW.....


o X o o X o





LOL...and with the donuts rotated lil bit so the 2 backed up to each other in the middle don`t grow into each other , and THAT way all light that gets past the plants get bounced right back at em .....

Compared to your diagram with the plants in the corners that , even though 5 plants would be hit by 4 bulbs with light on 2 sides and the middle plant being the biggest , the backs of the corner plants would have ta be hacked out due to lil to no lumen penetration/plant absorption IME....but......

I think he needs to run both to compare increased plant numbers flipped 12/12 sooner , compared to increased vegtime and overall end results taking longer.....but Bro...

He want`s to run 3-600`s for insurance against heat stress and upcoming rising temps , so for that I stand by 3 lights side by side with 4 plants on each side like Dabs is runnin , or even 10 with 1 plant on each end in the middle of the wall....anyways....

Good stuff Flat....

Peace....DHF.....:ying:......

Edit:....Cant get the o`s to line up in the right spot for some damn reason , but put 2 plants on the top and bottom for what I`m talkin bout.......
 
To be honest, if I had 3 lights to work with and that sized space I'd stick em all down the middle and slap chicken wire around it. I believe those dimensions will give you about 6-8 plants in 5 gal pots around the ring and you should still have scooting room around the edge. Then just put it on a drip system and you're golden for a damn near fire and forget harvest. I don't wanna say anything I shouldn't, but I've known some REAL out-there people in my day who grew and they pretty much all did it somewhat like that because it didn't matter how strung out they were during the grow, they'd still usually get a harvest as long as they remembered to change the res every week or so.

The whole ideal WSF thing doesn't really affect this kind of ring either, since you can just wrap the thing in plastic. Make a few posts out of 2x2s and wrap panda plastic around the outside. $30 and your 7x7x7 box just became a 6'x7' cylinder. Then you can just take it down once your plants grow into the space.

As a disclaimer, I hate doing big trees in small spaces (of the more-lights-than-plants variety). Tried it and couldn't stand it. Makes sense if you're trying to run something big by yourself or if you're trying to get around MMJ law enforcement but that's about it. I think it wastes too much light to be worth the extra effort over plain old horizontal lighting and trays. That's just my opinion.

No worries DHF I'm glad you're here to drop knowledge. Just saying what I thought of.

Hey SirStynkalot I love your signature on here regarding pants while gardening hahahaha.

Hey Stynky.....What you said was exactly what I suggested as in lights down the middle with maybe 1 plant on each end like Dabs has goin in his thread......but.....with the screen "behind the plants....

Guess great minds think alike...kinda sorta....:moon:.....anyways....

Peace....DHF....:ying:....
