Is that with Co2 and hydro??? Curious
It's all about lighting to an extent. I ran a 4.5x8 tent for years. My best yield was a bit over 4lbs. For that run I had two air cooled 600 hps. In the middle I had two 315s. Since the 315s were not sir cooled I switched them out with a 630 de cmh in an acde hood for summer. I didn't care for the de 630 but it fixed my temps issues since it was air cooled.
Average yield with that was just under 4 lbs.
If you can cool the space though the 1k hps is the easiest light to hit good yield with in my opinion.
When I first started growing I used a 1k light and always hit good numbers. When I started back growing after a few years off I started back in tents. Because I had always heard 600s were more efficient I went that route as well as some 315 cmh. Now the 315 cmh is great light for small spaces so not trying to knock on it. But 600s and 315s require a lot more work to hit good numbers in my opinion. You have to keep the canopy just right or end up with too much larf or low yields. I did it for years but then built a room and went with 1k de lights and a mini split to control temps. After one run with those I realized that it's just easier to pull weight with the big lights. Penetration is key to good yield you can only fit so many branches in a given area, once you are able to consistently fill a canopy the limiting factor to yield becomes how deep into the canopy your light can penetrate.

Old thread I see but I see 5lb as the ceiling for a 4x8.
Which I have never pulled but not been too far off.

No not necessarily. It’s imo a bit easier to grow fast with hydro and push out a bit more but a good dirt grower can reach those numbers just the same. More important is optimal use of the space with a good bud/cola to sqft ratio and of course a high yielding plant variety.
Do you have a grow journal I'd like to see how the lights do as I was thinking of trying a couple of them. I was surprised to see someone using them already.

5lb seems light for a 4 by8'. i get 4lb out of a 2 by 4 ft tent growing 8 plants in 3 gallon pots kellogs organic potting soil and mg plant food and mg bloom under a 6 bulb T5 growing SOG with no training

Pics? I gotta see what 4 pounds looks like in a 2x4. You are talking dry/trimmed weight right? or are you just kidding around?
I love your feeding system, what is?

sorry misread your post meant 4-6 oz. 14
sorry miss read the original post meant ounces not pounds. not use to claims of 2.5-3 grams/watt sorry

sorry I'm just an average low budget PU MMJ grower. I am far from being a master grower but I can grow enough high quality weed to meet my needs and those of my wife and thats all. I needdamn, I really wanted to see 4 # in a 2x4 lol I'd have to up my game a lot.

nothing wrong with S.O.G efficient use of space and good yields. commercial greenhouses use this method to maximize profits

1 800 gph feed pump out of a 55 gallon food grade barrel to top feeding 9 inch rings through half inch line on 8 separate ball valves one per pot to always balance the feed out between them. The return is a 345 gph set for 1 hour the 800 gph set for 30 mins valve shut a quarter way
