Flowering Under 315 Cmh

I think the significant difference in these lamp sources is the spectrum profile - CMH puts more of the consumed power in useful PAR and UV wavelengths that the other lamps are rather poor at generating. Certain important biochemical reactions can still happen with the lower energy levels of longer wavelengths, however they do take longer.

DLI is only measuring the quantum photon count - since usually applied to sunlight, assumes the broadband spectrum of natural sunlight. With artificial sources, we would need to mimic the solar spectrum to use DLI in a similar way since it may be impractical to adjust for spectral differences. Plants have photoreceptors intended for specific wavelengths - this is why spectrum matters.

23% tho... I just can't wrap my head around that.
My other thing is, heat.... I got 2 600w hps going in a 4×8 tent in open air reflectors. I'm wondering what heat comparisons the 2-600 compared to 3-315 and can I get the same yield, growth, and quality... That is my needs. I see the 315 kit with ballast outside tent. I need to know just what the light puts out with ballast outside tent...

I run 3 315cmh in a 3x6 area and I switched them out from 2 600w lights all ballast located outside my growing area temps dropped about 7 degrees with no other changes yield was effected in a good way by increasing, I noticed zero effect on maturation. I have all open hoods. Not sure if that helped but the 315 run much cooler than 600's. Also correct me if I'm wrong but isn't dimming 1k bulbs effecting the overall par and color range the bulbs put out?

I'd not get stuck on the 23% - Mileage will vary depending on many things. I know I can pull in a week or two by using a bloom booster along with CO2 and aggressive environmental control with Indi-hybrids and Indica. I've had less success with Sativa dominant strains - they just take longer.

Been running co2 for 5 runs nkw. Never has my harvest time ever went down. Still taking all my gg4 to 69 days. All others at 64

If your asking me, it probably is to some degree. I have 1 600w ballast... The other is 1k dimmable to 600.

I haven't noticed any difference. I plan on illuminating 5x4 of the tent with 1k and 3x4 of the tent with the 600 for right now.

And thanks for the info!

Seems as though it's hard as fak to buy 9 remote nanolux ballasts,11 phillips bulbs and 7 adapters. Going the sunplix fully adjustable/remote ballast route if I don't hear from my nanolux dist by noon today. Way to fail on a 2400.00 order nanolux.

Love the info in here! I have a couple of the 630 lec fixtures that seem to be doing great. I do have one concern...I'm curious how safe these adapters are that put a 315 cmh bulb into a traditional socket? I would love to use these 315's as verts for supplemental light but I'm concerned how safe this is. Has anyone on here doing this seen any problems or any electrical savvy guys see anything wrong with this?

Should work,the adapters work well and should fit in a vert bulb fixture connected to a 315 ballast.

They make a protective sleeve of sorts for the mogul. Not sure it the companys trying to make a quick buck on the ill-informed or what.

I just purchased two 630w fixtures to run in between 3 315. Gunna be awesome. The dimlux do run Cooler after seeing them in person today. It's why I made the purchase. Killer quality by the looks.

 

[EventHorizan]

I don't think ive even seen it. I might have to Google it. Dimlux huh.?

 

[DemonTrich]

Got my order in........finally.

9x prism 315 cmh ballasts
7x mogul adapters
5x t12 3100k agro philips bulbs
1640.00 shipped

4x 4200k t9 philips cmd elite from amazon
330

I am waiting to see how they work for you Demon, I am close to pulling the wallet out myself. I do not doubt the advantages at all, rather how to maximise the benifits...Yeah sometimes its easier to se others work aswell

 

[DemonTrich]

I should have everything on Sat or Monday. I'll swap out my veg room immediately. Flower room after harvest thanksgiving weekend.

 

[velocity]

Thank you alot Demon...My real question is pure cmh the way or add a liltle HPS...I think it is going to be how it works for the grower so yeah man back to testing LOL

 

[DemonTrich]

From my understanding, cmh has far superior par than hps/mh. I'd add another lec if possible. Mayne even mix the bulbs up, 42k, 31k.

I just purchased several 630w CMH fixtures. Welthink Dual 420, 630 CMH fixtures. I have a 9x20 room. The light fixture has a 6ft footprint. I was thinking about putting them on movers. Any suggestions at how many lights you would run on a basically 6x 20x8 room? I was thinking 4or 5. in a straight shot. Also, what were the growing pains that you went through going from HPS to CMH? What are your thoughts of throwing a couple of supplement HPS lights into the mix near the end of the cycle? I also plan on going with a longer vedge and scrogging in order to keep the plant count down within legal numbers. Any advise would be greatly appreciated.

 

[Neter Sentra]

No growing pains for me but I wouldn't use light movers

Anyone running multiple lights in flower (315 cmh only or de), anyone mixing spectrums? 31k and 42k? I'm running 4 lights, and can mix up the bulbs.
