Scorpion Diablo 650 'without' CO2?

Lights are on sale right now and I am trying to decide whether this will just be a waste of light and hurt my plants or not?
Would like to run it without co2?

Based on the Size of my Trees even with LST and because my fairly low ceiling height --- it will be hard to keep the light any higher than 18 inches off of the Top of canopy -- maybe I could go 24 inches if I improve my Training and start earlier.

This is what my plants currently look like. I have my Golosa measuring about close to 25 SQ canopy under 2 315 CMH and one HLG Red (r-spec?) 300 all about 16 inches with very little ceiling height left to work with... Total 900+ not perfectly positioned. I am getting close to a Pound with these trees but I feel like I should get more (another thread?)

I really can not be constantly stressing on keeping my plants below 18 without defeating the whole point of getting this killer light. I could just as easily get 2 Diablo 350's? And be satisfied. I keep a constant ventilation and my space is not optimized for co2 especially in the Summer! IT says in the description needs co2 to run full power. I guess I could Dim it too?

But then I also wonder if that would be silly to buy a light I can never run full power?
I am also confused if there are other factors why it becomes less efficient to run lights to high up over canopy that were designed to be closer? i.e. beam angle etc...

Thanks for you input on this! I mean c'mon who doesn't want one of the best lights on the market. But I am not going to get one because of some ego thing either...

You should scrog since you have limited height. I have 650 rspec and it's a battle to keep my plants low enough to run it a full power.
 
I run the diablo rspec with no CO2 and can’t run it wide open. Seems 500w of the 630 is optimal for most plants. My dad just picked up a pair of the new 3.2 scorpion diablos and they are way brighter. Running them dialed back also provided increased efficiency and longevity.
 
Id give it an educated try! But with limited height ld go spyder type bar light, even coverage and can run on full with less bleaching and problems bc of lack of hotspots caused by boards. Can go 6in from canopy with most. 12 inch no co2. Have colas 1in from bars, no bleaching. No co2
 
I have a little tent, and a single diablo board ran at full power burned my plants if kept close.
Wound up buying a second board when they were still selling them by themselves, and run the 2 at half power. No more burning.
I doubt co2 would have made a difference.
 
Another thought -- which is why I asked about dimming, and a higher distance having an effect on any other factors that I may not be aware of regarding light efficiency -- is because to think I could run it at 500 Watts and save almost 500 watts and still get the same yield?

That is the idea.. 50% less watts may be a stretch though, especially if you are currently using cmh.
I easily scrogged 1.5g per watt, or 50g per square foot first run under mine

This is why people get par meters. Your plants can only use so much light in their given situation, so dialing a light back can even increase your yields if they were getting way too much light to begin with.

Since you've been around your plants the longest and they know your style, you need to running the co2 based on your maturity level. For instance if you're 40 but run around the forums saying dumb shit to get a reaction like a 14 year old does or an 8 year old then you need to running 800-1400 ppm. There is a chart online somewhere. I'll find and post. Happy gardening!

Are you limited on plant count?

Thank you yes, that is why I grow Tree style. Limit in Vermont 6, 2 in flowering, loophole = up to 9 Civil Fine first one 50 Bucks!
I feel like I should be getting more than 1 pound per plant under 800 Watts or so. I grow RDWC in Power Growers and think maybe I need to modify my outter bucket to hold more than 2.5 Gallon since they drink about that per day at their peak! guess I only get about 1/2 gram per watt with single plants. I have seen some much fatter looking plants under the same system. My plants look healthy I think so signs of deficiency? I only change my reservoirs once a week but if they drink the full capacity once a day maybe I should do it more often?

Would you recommend one please. My tree style plants are close to 5 by 5 but lately since I opened up the space more of an oval shape

Thanks for your help...
 
One idea I had to run CO2 with constant ventilation is to string up CO2 tubing right into the plant maybe even using my 1/2 PVC armature. And set it very low constant release? With a Fan blowing up the CO2 being released in the middle of the Plant?
 
So I’m just gonna throw this out there. Bigger plants don’t always mean bigger yields. Looking at your pictures I see a huge plant that only has light getting to the top half of the canopy. Which leaves the plant trying to make flowers with half as much light as it needs. Now adding a bigger more powerful light to the top might add more light intensity, but it will won’t light up the bottom. Pretty much all of these lights are only going to effectingly light up about 30 inches deep of canopy. So having plants taller then that is ends up being wasted veg time IMO unless you can light the whole thing. Another option to growing smaller more efficient plants would be adding side lighting. There was a grower here for a while named Renfro, he used to pull 50lbs from 12 plants regularly. He grew big trees in 10 gallon pots with metal cages for support and surrounded them with lights on all sides. He was running 19000watts around 12 plants....

I have thought about adding side lighting too great idea. But if you look at my plants the canopy is only about 16 inches of buds

I was looking at that second picture. It looks like a deep canopy when compared with the 5x5 width you described and a large amount of the plant not being lighted. It might just be an illusion from the pictures.
