I challenge you to a duel!

This going to give me an idea if I want to try a 6 pot SOG. Dwarf strains, perhaps. It would require adding to or upgrading my LED wattage. I was using a 350 in my 2x2x4.5 (veg side of tent.) That was giving me 87.5 watts/sf. Upping my wattage to 450 and opening my space to the full 2x3 would drop my w/sf to 75 and adding a little distance between the light and canopy, losing plant height. Getting a 600 watt would give me 100 w/sf, increase distance between light, more heat (not an issue). I've read on other non GWE sites that 75 w/sf is adequate... or plenty. I can add a 150 watt LED to hit 500 watts total and 83 w/sf.
 
Gingerbeard I tend to think you’re going to need to use additional tactics to get the plants to accept the increased wattage without burning the leaves. My LEDs can exceed these numbers but I must dial them down or I get leaf problems. I also tried CO2 but my exhaust fans suck it out faster than I can blow it in and I never tried to balance the two. Monitoring those CO2 numbers is around 850 to 925 which is not too shabby but it would be better off at 1500.

Not sure of the cost of these lights but as I hear it, there are big lighting changes in LED coming soon... kinda like led tv’s. Last few years they’ve dropped in price and risen in quality
 
Thanks Farmall
I'm thinking about adding a 150. 83 w/sf isn't a huge drop from the 87.5 I'm getting now. My distances have been good. Never an issue with light burn.
The only extra CO2 my plants get is if I breath heavy into the tent.

I was thinking you’re shooting for a higher light output. I had those LEDs just a touch over 55%output. It was BRIGHT . The beauty is it is not hot. The heat sinks barely reach 84 and remote drivers get about 120 -130 at full power
 
That's the thing, Farmall. Being still just inside of my first year of growing, I'm happy with the light I'm getting. I don't know any better. I'm looking to add more light only to take care of the extra 1x2 space when the dividing wall is removed. Do I need more light per square foot? Is 75 w/sf enough? Is 100 w/sf too much? Dunno. My setup is super simple but quite effective so I don't know if I want to increase the overall. l/sf. Only light on the 2 sf I'm adding.
My average plant dimension cannot be more than 2'x1'x2'.
Dabber needs a walk. 2:00 and 5:00 this morning apparently weren't enough. Good thing I love that dog...
 
50 actual watts a Sq ft is a is a good number, 75 is getting high.
I have a 3x4=12sqft tent with a 600 watt light,
600÷12=50 watts a sqft Gingerbeard if you need a link I can provide one.
What you need is a par meter.
 
I'll take it Mr.F.
I don't think I'll get a par meter. It would only be used once or twice then sit in my dope growing nic-nak box. I do have a water/light/ph soil probe. The light numbers hit 1000 whatevers at 20", down to 500 whatevers at the periphery.
I've been at 87 with no burning or bleaching or other light issues. 100 w/sf is too high. 50 w/sf seems low. A 450 watt LED would keep me pretty close to where I am. Budget wise a 150 would be better. Still time do decide. Hell, I have more decision making time than most people who have to make decisions. I average .75 a day throughout the week so as not to stress.
 
I'll throw him a seed in the pot so he can compete. I'm taking my vacation over the winter so will just have maybe 5 plants plus the farm so I'll have time. He is my bud so I'll win for him.
