A 315 cmh has no where near the coverage and intensity of a 1000 watt hid.

I have the sun system and a Phillips 3100k and I do really like it but it doesn't even compete with my 600 Hortilux Super hps either. Lotta hype that distracts the buyer from the small coverage area with high gram per watt claims.

It covers 2.5 to 3 feet square for flowering. I will use it only as supplemental spectrum to my 600 hps until I can try 3 in place of my 2 600's.

I have found it has the power of maybe 450-500 watt hps but only the coverage area of a 400.

I do really like the natural looking light to work in.

It also is as hot as my air cooled 600 hps but in an open reflector. I did need to add ventilation for it.

Seems growers with multiple overlapping lights are seeing the benefit as a stand alone lamp more to me.

It does increase resin production, frost and color over the hps. And some strains are finishing faster. I really like them paired with the 600.

I have been trying to figure out how to fit it in between my 2 600's. That would add the perfect amount of blue light for flowering and a little uv. If I went with the 4200k bulb even more uv. Even some uvb.
I think you're right, my first run with a CMH was using a 600w until halfway through flower and switching out for the CMH toward the end, got far superior yields than with either alone. Some people do switch from HPS to metal halide towards the end of flowering anyway, I can only imagine the CMH is slightly better than that.

I'll save my reservations until I do a full run of 630w CMH myself and compare that to my HPS. But my HPS yield with autos is still way off my CMH photos right now.

Since I made that post I have been trying to figure out how to fit my 315 in between my 2 blockbusters in the frame I already built.

I have a plan to relocate the inline fans to a "Y" duct and then could carbon filter the 2 lights like they are now and another exhaust duct pointed at the 315 reflector with an inline filter I have.

Work is never done. Lol:-)

I tried a few configurations in my little room. Here is one. You can see why I want to do.

I will spread them out more and stick the 315 right in the middle. It will all be a 7' x 3.5' area. 1515 watts with the improved spectrum.

My best plant so far and biggest also flowered under a 600 and finished 2.5 weeks under the 315 LEC.

I think pairs would be best over a 6' x 4' area but this should give me good overlap and I would keep moving plants around and rotating as I water.

Here's what I have been using all summer. 600 Hortilux blue mh and 600 super hps. Excellent quality and yield but still too leafy buds and a bit looser than hps alone.

The quality was higher like with the cmh. And it produced the colors wihout cold night temps. Also kept plants shorter.

But I don't like the 50/50 split in the room and I am trying hps only to compare right now. The last two plants harvested are still fire. I have 2 more to compare soon. The frost is less but still really frosty. The potency is close enough that we are not sure. The flavor and smell are still strong and distinct with the 2 different strains.

But the leafy buds are obvious and I have twice the bud leaf trim and loose stuff I used to


I don't lab test anymore. So I don't have numbers just mine and Mrs. MMG' opinion and a bunch of patients. Laying real low since the new laws at the new year. Not dealing with dispensaries.

Just hang one vertically in a socket in between the 600's?

I really have thought about this. It is likely the best solution. But for safety and ease on my eyes I really prefer reflectors. They are pointing the light below my standing eye level in my short room.

It would really mix the light spectrums up real nice.

But isn't it a waste if I am hanging the bulb above the canopy?

When I did a vert grow a while back I got these sockets than plug right to the ballast and hang meant for this very use. I would try and hang the 315 this way and see how close to the canopy I could get with the bare bulb. Go from there. You can always use the reflector again if you need to right?

Ive heard tall tales and outrageous claims from these 315 watt cmh fixtures as well. Everyone joining on the hype train. And you sir are correct. Many of my grower buddys arw finding these to have optimal coverage at 2.5 x 2.5 square. 3x3 is max and thats pushing it. One buddy grows big plants and has relegated one Sun Systems 315 in a 3x3 covering ONE plant. And it kicks ass but to compare these to mogul socket sixers or thouies in yield is pinnochios nose. At least what ive seen first hand in about 4 grower friends ops. Hell...all the industry even says these are optimal for SUPPLEMENTAL lighting for flower. But there is no question these are the better spectrum for more tasty..smelly amd potent end product. Its obvious because of the cmh sun like spectrum. In veg ive heard but havent seen these blow past t5's and standard mh hid lamps. What iam getting a hard on over is the very new double ended cmh fixtures just now coming out. I like the 630 i think. And these seem like they would pair up nice with 600 watt double ended hps in a flower room. One for every one for the bees knees in quality and quantity. Again this is just what iam thinking. But what i do know is the initial claims of comparable yields of single ended thouies or sixers has not happening. At least im the few growrooms around town i have visited. The irony here is just the opposite of when LED first hit the scene a few years back. It was the manufacturers and marketing that made the bold claims that growers found out (at a pricey cost) werent jiving. With the 315 cmh...its the growers themselves making up some tall tales. Anyone notice that no real pros and veterans are making these claims and the big players with huge operations? With all this said..i want 8 cmh 630 watt fixtures. One for every Gavita 600 double iam running now. Inna checkerboard pattern. One blue..one red..so on. Iam thinking hps for the weight. CMH de for the quality. One thing is certain....the old paradigm of mogul socket HID (hps for flower...mh for veg) is gone forever. I been growing steadily since 1991 and i have seen alot over the years but nothing like the advancements and choices in the last 5 or 7 years we have made in lighting choices. Just so many it makes my head spin. Led..cobs..compact curly floros..double ended hps and cmh..plasma..Just all kinds of lighting choices i got blasted with in less than 10 years. Before that it was single ended mogul socket hid for veg and flower..and t12 floros for cloning...and that was IT!!!! Not to mention vent fans. All we had in the early days were the dreaded "squirrel cage" blowers and for smell.. "Ion fountains" and ozone machines. God what a joke those were. In line blowers and charcoal filters really were game changers. A grow tent? That was a plywood cabinet lined with mylar and you made it yourself. Lol. Enough rambling. Iam done here. Iam higher than a Georgia Pine on some Glue right now. Good thread though. Carry on growers.

3 315's work great, i agree the 315 is better when u use multiple fixtures, i replaced my 2 600 watt hps with 3 315's and im not looking back, higher gpw, plants finish faster, and im saving 255 watts... i also like the color for taking pix in the room,,no more orange tint...

Not a 8 light setup.... but what ever... and he give first had experience.

It's the grower that makes things work,not the light.....

Even the few big ops in Colorado I went to,was running walls of 315lec(but them was production ops,so not much care for the plants)

Common sense should tell anyone,that 315 watts of anything is not compatible with a 1000 watt....

Yes but the common claim is it is a direct replacement for a 600. But it really is closer to 450 watts of hps for coverage.

When i got my first 315lec's,I was told they was just very good lights...not a replacement for anything..with a 600 over a 4x4 & 2 315lec over a 3x6 (same clone).. the 315lec out preformed the 600...in all categories.

Running the same clone under 600hps then 315lec.... I like the 315"s 3x3 canopy.

Well I'm not surprised 2 would beat 1 600 eapecially in the proper footprint you used.

What do you mean you like the 3x3 canopy? I try to stay 3.5'x3.5' under a 600 for best results.

And would you prefer 2 600 hps with one 315 in the middle or 2 315's with 1 600 in the middle over a 7' x 3.5' area?

I can't decide if I want to get new hps ballasts as mine are 3 years old or another 315?

That's what I'm trying to figure out, I can run 2 315lec"s in my setup but from my understanding it won't give me the same size nugs of a 600. I ran a 1000watt hps in a 4x4 and it was sick and so was the light bill

Ok before I spend my hard earned money let me make sure I understand. A 315 lec cover around 3x3 area and the benefits are more resin production,better color and smell followed my no exhaust fan needed to cool off the light bulb, and less use of electricity. But I will have smaller size buds ! Did I hit the nail on the head?

They get as hot as an open HID bulb gets. You will likely need ventilation. Never heard no exhaust needed. Well unless it's a sealed air conditioned room.

That's the setup I ran it in...a 2x2 tray filled with 9 -1gal pots of Rich soil/feed was Neptune's harvest,with a 3x3 canopy over top.

I always run the 600's/1000s over a 4x4 (depending on hood spread )

I like the sounds of 2 600/630DE-R with a 315lec...

But if I would of got that (sun system grow beast) I would go 2 315lec with a 630DE-R...

That's what I'm trying to figure out, I can run 2 315lec"s in my setup but from my understanding it won't give me the same size nugs of a 600. I ran a 1000watt hps in a 4x4 and it was sick and so was the light bill
I just think the nugs development under the lec give off that deception,of being smaller.
It just stacks different.
