3ks over an 4x8 d-w table

[St3ve]

where does your waste go? Into a floor drain? It wouldn't be hard to plumb buckets to a pvc that runs to a floor drain. If you drain into a rez then you'd have to get the pots up all the floor.

Yah floor drain. Thought plumbing the run off lines from the tables to the drain hole was best. How ever I would like to yield optimally. Any other suggestion?

Thanks Steve

Would like to do as much vert as possible

if your going for yield IMO would stay away from Vert pretty simple really 2 k lights 4 x 8 and your going to get the best possible outcome theres many variables on yield health of plant proper feeding no major issues i read up somewhere someone saying 600 watts is better actually its not as for dense nugs and yield i find it funny when people worry about gram per watt who cares its about yield were not talking efficiency here were talking total penetration power i just yielded 4 pounds with 4 plants 2000 watts pretty much can;t get any better then that total days 84 Veg n flower
so 280,000 lumens compared to 170,000 lumens a 600 will give you is to me a day and night difference in final yield

600's work best for me at 37.5 watts/sqf. Its simple really... More lights of lesser power=more even light distribution= more yield per watt. 5x600's will yield more 3x1000's using the same amount of energy (3000 watts). Now if your doing 20+ gallon pots, with horizontal lights, 1000's may be better because you have so much vegetation to penetrate, but if your plants are that big, you would want to implement vertical lighting. I use 600's for anything in a 5gal or under. If i was in a vert setup, i would probably stop using them for anything more than a 10-15 gal pot.

I think you guys should check out Marlo's thread in the vert section he has a 8'x2'9" flower closet and he has a real original set up. Sorry I haven't figured out how to place a link or Original quote in a reply yet. I think you will get a kick out of his version of a light mover.
I also believe a 600 can do just as well as a 1k. It can be placed closer to the tops and creates less heat and I believe two or three 600w plumed together over a 4'x8' tray will out due 2 or even 3 1k's in quantity and quality being that they can be placed about 12"-24" over the plant tops without scorching them like a 1k.
Believe me I was a 1k or nothing kind of guy for a long time and no one could tell me different. A 1k will help grow very large plants over all but I like to consentrate on growing tops and one way I feel I can keep'em short while still having a very large plant is with ScrOG's the over all height is say 2-3 feet from base of roots to screen It was only when I started concentrating on the enviorment ie; temp, humidity, co2, static pressure, and clean flowing air over the leaves then I started to see a real difference in bud structure and a over abundence of crystals giving my a heavier stone and better quality of buds that is were you should try to focous your attention and your ladies will thank you for it
Sorry I didn't want to come off as ranting just trying to help,

like saying a person running 5 400 watters is comparible to 2 - 1000 watt bulbs sorry folks it isn;t its not even close it never will be
i have done 5000 watt grows side by side using 600's in one room and 1000 in another and trust 1000's grew faster grew denser and out yielded the 600's sorry to say the 600's were stretched plants which i knew that was a given
now for the op 4 x 8 IMO 2000 watts would be perfect considering i just completed a 5 x 8 scrog table 2000 watt grow 4 plants 4 pounds ) my next grow will be going for 1.5 pounds per plant lets hope it happens with some tweeking and little more training

Were you running the rooms exactly the same? As in spacing, plant # etc..

 

[DrFever]

Yes Sir same strain same amount of c02 same feeding and the same plant count 72 plants in each room
vegging was day and night difference 1000's blew them away
and as for final yields i beleive i got almost 2.5 pounds more with 1000's my lower bud sites is where i gained weight 1000's got penetration 600' grow lower bud sites were junk

 

[dieseldrew31]

If i came off as biased towards 1000's sorry I was pretty stoned when I typed that 1000's will allways have their place as the big boys on the block. I ran them for a long time, each style reflector and ballest finding what worked best for each grow room I've built. I started to realize that 600's have their place as well; for instance the days are reaching the low 90's now and if I continue to run 1000's my growth will grind to a halt.
If you haven't already guessed I live in Florida and our seasons are like this 9month's summer, 1 and 1/4 months fall, 1/2 a month winter, and 1 and1/4 months spring. So I have to limit heat were ever i can and 600w's are the logical step and when you compare both to lumens and their distance to heat ratio you end up with certin compromises.

 

[dieseldrew31]

And yes inthe end 1000's have more lumens wich enable light to penitrate and make large tight buds but, with that much heat they will have to be kept further back and that limits the amount of lumens the plant recieves in the end you still end up trimming as much undergroth to eliminate fluff.

Ok there really needs to be no more agrument on this. Its a well known fact that more sources of light equals better dispersion and more efficient use of light. 400's would even be better than 600's but most people dont use them due to the cost for extra hoods. And the fact that there is not enough penetration usually unless you are growing a very short crop. Like i said, when it comes to penetration, 1000's may work better with huuge plants, but for most of us that dont veg plants for 3-4-6 months, 600's are the way to go. I can easily achieve 1g/watt under 600's when flowering from clone with absolutely NO VEG TIME, which comes into play when trying to operate efficiently. Less veg time=less electric, less equipment, less nutrients, less maintenance, less money, more space to flower plants, ect... With a 5-7 day veg, i can get even a better ratio. To set up this short veg phase, it only costs me a light, a 4x8 table and light mover. All of which i have lying around. I have done the math and the extra gpw from the short vegged plants definately over compensated for the additional electric, maintenance, nutes, ect... The longer you veg, the more inneficent it becomes after a certain point. I would imagine any veg more than 2 weeks starts heading down the inefficient path. My gpw peaks around 10-14 day vegged plants being flowered. Any veg time after that, and my gpw seems to stay the same or decrease.

A quick question here...
If i was to do 3x600w on a 4x8 table...would 10 plants in 3gals of coco/perlite work, or should i increase plant numbers for efficiancy? I was planning on a 3 week veg with Sour D in mind..
