My last run i just got 49 ozs 19gs with a multi strain grow. I ran 8 plants in 10 gal pots under 2 1k bulbs veged for 5-6 weeks i don't count veg days. If i would of ran all rare darkness the biggest yeilder of the 3 prob would of hit 4 #s. i think about 4.5- 5 is max for conventional horizontal lighting. You can get the same numbers with a sog grow though with a couple day veg and get more harvest per year if plant count isn't an issue

I'm running independently cooled lighting, the heat is never an issue, I use a 6" blower just to cool the lights and an 8" blower/filter to control air temps and humidity. I've been consistently pulling 20+ oz per square meter so hopefully this room follows suit. Fingers crossed.
To be honest eventually this room will have 2 or 3 1ks and co2. If I was you I wouldn't change to 6s. The 1k is a far superior beast, foliAr penetrAtion from a 1k just can't be beaten. So far my biggest advance in lighting has been in the form of cooltubes and adjust a wing reflectors. These enabled me to get the bulb as close to the canopy as possible whilst still giving me a good spread.

Those are the cubes mate.

4 lbs a 4x4 with ~1500 watts of hps isn't really doing that great with a strain that yields...
I can sometimes get ~3(just under) out of a 600 watt hps in my 2x4, so with 4 of them that makes closer to 9, an that's with 600s not 1ks for lighting...There is a reason I gave a space max and realistic match..

If you want more yield, you'll need more light. 2 x 600W HPS will give you what it's given a lot of people; 24-32 oz.
I've pulled 4lb from a 4 x 8' under 2 HPS thouies in magnum XXXL hoods.
If you want to pull 5+, you'll need AT LEAST one of the following;
1. 5 x 600W HPS
2. 3 x 1150W double ended HPS
3. 4 x MH thouies
4. 4 x 860W CDM in vertical hoods
5. 3000+ dissipation watts of COB LED
...and of course the environmental control system to deal with it, which will likely be even more expensive and power hungry than running the lighting itself. Sealed room and supplemental CO² is also all but mandatory.

4 lbs in a 4x8 with 2 x 1000?
Hmmmm....maybe my expectations are low or maybe my skilz are...
I was hoping to get 3lbs in a 5x9 with 2x1000. Gotta up my game.

When u got 4lb what techniques were you using, scrog? Sog? Lst?
How many plants? Eventually I want to be getting 3 20+oz plants as a minimum. Think I've got the right strain right now, will see after the next run.
Space has allwAys been my limiting factor. I've seen yields go up all the way to 100watts per square foot, my best yield with that was 3oz per square foot.
3 thowies puts me at almost 100wpsf so with that logic a 32 square foot space should be able to yield me almost 96 oz. In theory.

I did ScrOG with six plants in RDWC. Interestingly, I had six more plants in exactly the same RDWC, under another 2 kW of HPS in magnum xxxl hoods, over exactly the same area, in the same room. That one only pulled two and a half pounds. Go figure...

It's all about finding that sweet spot pheno where it produces the right amount of the right quality in the right amount of time I guess. Hopefully my nl5xhaze pheno can produce 20oz plants. Rdwc does offer serious yield to people who do it right. The trick is getting it right consistently, a trick I never mastered. I built a rdwc system as a newbie, ran it for a week and a week later it was being used as a stand and means of draining my dtw trays lol.

Going out on a limb here, but it sounds like you didn't give it enough time?

2x1000w hps
3 week veg from clone
2 gallon smart pots Coco DTW
Raw Diesel and Jackberry X MadScientist
A bit over 2lbs each side.
I only fed them 2x a day for one minute.
H&G cocos A&B
9 plants each side also.

Your Killing it man!
Might have to give coco a try!

Coco is where its at, home hardware sells decent coco for $9 a brick, just rinse it and charge it with some nutes and calmag. Keep your ph at 5.8 water with nutes once or twice a day allow for good runoff and kick ass. Qp plants in three gallon pots are no issue

3 pounds from a 600 in a 2x4 ???? Do you mean 4x4??? Those are some beast yields . I am pulling 3+ with 1k lamps but not in a 4x4 I use 5x5.5

For me it has been more about space than light as an issue. And no I meant a 2x4, but my 2x4 tent is the sun hut one thats 2'8'' x 4'4'' so its a little bigger than a regular 2x4. You have to think in terms of a 4x8 for the point i was making because while I would put 3 x 600s over a 4x8, I definitely would not put 2 x 600s in a 4x4, because I can max out the yield in my space(as much as makes me happy, usually 1.4-2 gpw) with 1 x 600 watt light. I have actually been converting over led since I have been seeing these guys pull almost double what they were doing with hps/watt. If I can double what I pull electricity wise I'll be at 3-5 GPW which is unheard of(as far as I know), we had 5x20 rows that we were pulling ~16-25lbs (mostly depending on genetics) per row with 5x1000s hps over them.

Yeah that's correct mate, My job was taking up way too much of my days and rdwc just asked too much of me. Now I'm in a position where my job asks less of me but I'm just getting my drain to waste system dialed in. I think I will probably try dtw aeroponics at some point. unless I can figure a way of running dtw dwc. I like the set it and forget it res changes which mean I can literally leave my op unattended for a couple weeks at a time and not worry about nutrient lock outs due to ph swings.
