If you go back a few pages, you will see a post by db...& just get 2 single 315 lec

His post saved me about 1200..

I was going to get that de 630 with the grow beast sun system..
Now I'm just getting 2 315lec.

i second this.

I'm running a handful of the 630 doubles right now and they cover a 4x4 area nicely but i get a lot of shadowing around the edges and there is cleary a 2.5x2.5 foot bright spot in the muddle.

from now on il probably run single 315's side by side to cover a 5x4 area with a little gap in between each row to then make 4 lights cover a 5x8 area. same juice but less shadowing due to light sources..

now if ur a total baller and got the ceiling/cooling then id put a 630 in every spot and use 4 to cover a 5x8 area and i would imagine get buds the size of traffic cones lol..

il prolly always use 315's from now on tho.

interesting note, with the more availability of iron free glass I've started looking back into air cooled and the industry seems to be on the same trend. air cooled gavitas are coming. air cooled DE in general is coming. air cooled LEC is coming too. theres at least one out now but it doesn't have glass and its just kinda weird imo but I've seen prototypes being tested on IG of the 630's and the 315 hoods that were air cooled with iron free glass.. imo this is gonna be an amazing set up for tighter spots. i bet you could get away with the 630's air cooled with less then 7 feet of height and still be able to grow 4 foot plants.

I have 2 Dimlux expert series 630 DE running in a 4x8 tent. I have to say these lights are impressive. They are dimmable with 6 watt options including an overdrive 720 option. The veg penetration is amazing. I'm on the second week of flower now and I've noticed they put on flower quite a bit faster than hps does. Subtle color differences already as well. Can't wait to see what they pull and deliver the news.

I have the 630 from Nanolux running. I love it! It's changed the whole structure of my plant. The whole thing, including the leaves are thicker, and more robust. If you're running multiple 630s they work even better. They work a lot like the DE with the interlacing light pattern. You can get good canopy penetration with that since much of the light will be coming in at an angle.

I've heard about the bigger CMH fixtures too. The lifespan is much shorter making the ROI a bit slower, but the quality will go way up. That can help compensate on price.

I'm considering the nanolux630 as the lighting source for my first medicinal grow in a 4x4 tent, would you recommend this, or no as it is a commercial fixture?
or would I be better to run 2 separate 315's in the 4x4 tent?

How did the 860 allstart end up working out for you on the LFSW ballast? I know last time we commented back and forth you said you liked what you were seeing, just wondering what your thoughts are after completing a grow with it, thanks..
Click to expand...
They're in my veg because the power savings worked to my best advantage there. They seem to be doing well. I still think they won't hold a candle to LED.

Yeah I wouldn't really expect anything to really compete with COB's, I didn't know you were using them for veg only, I've got a lot of COB's going now in my horizonal grows I plant on switching to COB in my vertical grows too but I just can't do it at the moment.. I know I talked about using these 860's with LFSW ballasts before and I recently found a few BadAss Ballasts for about 200/ea was thinking about giving them a go.. Also are their 860 allstarts available at a warmer color temp than 4100k?
Click to expand...
Those are good ballasts if you plan to run any 1kW HID lamps, let alone 860W CDM lamps.

That said, I'm a COB-vert; I'm looking to replace all my HID wherever they may be found in my setup.

Cobs are now a little further down the road for me. Ive seen what cmh lamps can do at a fellow growers setup recently. For yield....they cant keep up with equivalent double ended hps...at least the 315 lamps ive seen. But thats only part of the story. Where they really shine is in veg and as supplemental to double ended lamps in the flower rooms. An experienced growers pal of mine (who i haven't seen in a few) recently took me to a spot (his main one) just a couple days ago. He replaced all of his t5 fixtures in his veg room (except the small ones for his cutting rack shelves) with the 315 watt cmh lamps. And WOW is all i can say. His plants in veg are compact...very healthy...nkdes and shoots all over. Very strong stem and root growth. Looks like that perfect early spring day that is familiar to outdoor growing. Just a perfect lamp for veg. The differences over t5 lamps is VERY NOTICEABLE. Dont get me wrong..t5's are a damn fine veg lamp...them 315 watt cmh lamps are jaw dropping. And they dont heat up much more than t5's for what your getting. ( in multiple t5 lamp veg rooms - they do throw off some heat - period). And in flower i seen one 315 cmh for every 2 double ended hps lamps and the quality is much better than tue equivalent wattage of double ended hps alone.Much better trichome coverage (especailly in late flower)...smell...bud density...all of it. So the real deal with them isnt either or. Its using them to supplement the yield giving double ended hps for a better quality crop...and replacing t5's in the veg room with them. Iam about to ditch all my four foot 8 bulb t5's with just 3 315 watt chm lamps. And 4 more in the flower room....to place in between my 8 Gavita 6/750 lamps. I saw it with my own eyes...cmh lamps are damn near perfect for veg and a supplement to hps in flower.

I've replaced all my 600w MH veg lights with 315's. Definately was worth it :-)
I'm all about the DE's in my bloom rooms too. Well kinda.
I'm currently farting around with 2-- sunlight 630 cmh's. Pretty damn impressed so far. Each one is over a 4x4 tray.
I'm also dabbling with three of the 630w DE cmh bulbs. Put into a DE setup(supposedly doesn't work in actual gavita brand though) and ran at 600w's. So far, i'm liking these things better than the 630w sunlight fixtures, because I can always go back to DE bulbs and turn them up :-) plus each setup is half the price of those sunlight 630's.

The verdict is not out yet on which one yields more, but a light meter shows them to be just about as bright as each other. And hopefully this DE/cmh bulb catches on and some bigger names start manufacturing them. I'm rocking these:

Never ran DE fixtures, but switched from hps/mh to ceramics and my gpw has been way better w/ ceramic's.. 3 315 watt cmh produce better gpw than 2 600 watt hps.. 945 watts ceramic better than 1200 watts hps hands down!!! switched my veg room from mh to the cmh and i can say veg growth has improved, closer nodes, on both cuttings and seedlings

You say your yield is more with the 945 worth of cmh compared to the 1200 worth of single ended hps? Same strain...same canopy type and what not? No other dramatic variables? If so...that is VERY interesting. Thats a savings of almost 300 watts for the better yield. That would really add up in bigger setups. Looking like single ended (mogul socket) traditional mh and hps bulbs of any wattage are getting left in the dust what with all the new lamp technology out there. Double ended...cmh...cobs...plasma...its definitely a new day for us growers. I knew eventually traditional HID lighting would get surpassed but not so extreme with all the different options....and pretty much all at once.

I'm 10 days away from finishing a 5 light grow. All the double bulb fixture 630 CMH Dimlux pro. I'll get a minimum of 5 lbs but with how big these colas are it could be closer to 10. I'll post pictures when I get back from the holidays and post weights after they are done. Anyone that says yields don't compare have never run them because I'll never run old technology again. I might stick 2 DE in for mixed spectrum but this yield will determine that.

What about temps for 945 CMH versus 1200 HPS? I assume 1200 HPS are two 600s.

Good question. I know in the spot i visited recently the all cmh veg room (on an 18-6 photoperiod)....the temps were VERY manageable. About the same as an all t5 veg room...maybe SLIGHTLY more. In the flower room and with 315 watter cmh lamps supplementing Gavita and Nano doubles...i couldnt tell ya. His mini split handled it fine. But i didnt ask him if he had to upgrade his split to accommodate the added cmh fixtures.

Ball park how many lights in 18/6 and how big a room.

I know a guy with a licensed grow who swears by vertical lamps being much cooler. He was talking parabolics/umbrella 1000 watts with bulbs pointing down. He said much cooler than horizontal bulbs.

He had six 315 watter cmh fixtures in 13 x 8 room i believe. But he had a nice perimeter walkspace. The 6 lamps covered a homemade corrugated runoff table 9x6. Each cmh covering a 3x3 square. He said he had quite a few 8 and 6 bulb t5's in there along with a few old school halides. Running 1890 watts of cmh in veg now and killing it. I figure i can run 3 or so of them lamps...ditch my t5's....and have an awesome veg room. I run a perpetual setup and perfect veg is key to my op.
