My god those are healthy!!! Those are under DE 630?
Yes, they don't seem "squashed" like cob vegged plants.My god those are healthy!!! Those are under DE 630?
I really like the dark green look. To me shows tons of health in the plant.Is that what you see?
I can't either. Makes more sense to run 2 separate 315cmh over this bulb. Has to be an approvement over the de-hps for most people though. Definitely run a whole lot cooler. At a loss of almost a 1000 umol thoughSunplix sells a specific ballast for this. Run your DE 630 cmh at lfsw.
I can't get behind the logic of the de 630 since its only two 315 arc tubes, the design leaves it more fragile and prone to failure due to thd/acoustic resonance than the single 315s. Personally I've found the allstart 860 on a lfsw 1kw digital kicks most ass.
Damn i haven't been in here in a while but i seen this and had to sign in bc we in the same boat ..u make a good argument but some of what u say is wrongHi guys, new to the forum. Just wanted to post something here for anyone else looking and thinking about the DE-CMH. I saw this thread and had me interested so looked into the de-cmh. To be honest if you are looking to upgrade your 1000w de-hps then this would make since but this would not make since if you were replacing lights all together. Let's look at the technical data of 1 de-cmh vs. 2 315cmh since this would be a watt for watt comparison.
DE-CMH 630
1150 umol
65,000 lumens
10,000 life hours
CRI 97 supposedly
2@ 315 CMH
1197 total umols
66,000 lumens
20,000 life hours
CRI 92
Now, we do not know how much of a drop we are actually seeing on the DE-CMH in real life due to the fact that they recommend this bulb to be cut back to 600w on a 1000w de-hps ballast as the ratings given on this bulb are for 630w of power.
We all know that umols or lux is what counts when the color rendering is that close together and the 630 de-cmh is already behind on that watt for watt even when using figures for 630 watts of power when most that buy this bulb will be doing it to do a 1000w de-hps conversion and will only be pushing the bulb at 600w.
The de-cmh would be the way to go if you already have a de-hps 1000w ballast and reflector. If your just upgrading your gear all together then your better off going with 2 315cmh for better umol, better lumens, and longer bulb life, and better light spread. Just don't see how this bulb could outperform 2 315CMH or 1 1000w de-hps for that matter.
I don't know what the deal is but I read everyone saying how great they are but I've never seen any grow journal/video that actually shows anything impressive. I like the idea and I'm sure they're great but put up against HPS in pics and vids I don't see it...other than maybe monthly savings in electricity and bulbs.Cob's or nothing bitches lol
A 1000DE or 630DE in a AC/DE hood will do just fine in a 5x5 tent...I know this light just came out but has anyone found someplace where they're flowering with it (GC-630)? I'm planning a lighting upgrade, still using my Mars II 1600 in my 5x5 tent.
WARNING: MEANDERING POST...I've been tossing between COBs, CMH, and 1000w DE in an AC/DE fixture. I kinda feel cursed with this 5x5 tent, seems like all lights are geared toward 4x4 spaces or multiples of 4'. I love the idea of four 315s in there but the cost is on par with COBs and there's a good chance heat would be a problem. Watts are cheap where I live, I just want even lighting for my 5x5 scrog. That 630de looks like a pretty narrow footprint, guessing 3.5'x4' or something. I wish they would post the lighting map of par values at varying distances on a grid.
