Cant see a 600 watt being better vs a 1000 watt

[Jbone77]

yep, 600s are more efficient so id pick 2 600s over 1 1000 or 3 600s over 2 1000s, but if I had to pick 1 light for a tent and wanted max yield and had an extra ac unit id pick the 1000. I love 600s, just depends on how you utilize the light tho, hypothetically if you went vert and grew trees around a 1000 that is tough to beat, a conventional air cooled 600 is also tough to beat, a led scrog is also tough to beat. Was that confusing enough for ya? A vert cmh is the hands down winner

Having to raise the light is a non-issue if you have the space. Light doesn't stop after 20 inches or so. In the professional setups for which the 1k bulbs are designed they are attached to the ceiling of a greenhouse not hanging in a tent

I firmly believe that the spectrum of HPS light sucks.

That claim is getting old very quickly.... ....like the type of bulb you are "testing".

but if I had to pick 1 light ... id pick the 1000.

Exactly, let us not pretend a 600w is "better" than a 1000w, it's just more efficient to spread out the lumen, which obviously is made even easier with 2x600 than it is with 1 x 1000. I too rather have 2x600 watt instead of 1x 1000 (because of the 200watt difference alone, but also because it's 32sqft vs 25sqft) just as I much rather have 2x 1000w than 3x 600 (getting 50sqft instead of 48sqft and 200watts extra). That's what dictates the best choice (600s or 1K-ers), the space you have to work with. If that's a 5x5 tent... the best choice should be obvious.

Rockin' it now, we'll see if it lives up to the hype, brother!

Hey, glad to see you in here! Hope you saw my earlier post about having a brace of brand new HPS bulbs ready for action if/when CDM tech fails to live up to its billing.

I take exception to your comment about expectation bias coloring my results- let's see your data? I've got REAMS of it, motherfuckers!

I see all those lights mounted to the ceilings of greenhouses and shake my head at all that power getting wasted...

Finally, it IS all about the spectrum. HPS spectrum sucks for growing plants and anyone with half an education on the matter will confirm this for you independently. Confirm it for yourself by looking at the spectrum output graph on the HPS lamp box and comparing it with what LED manufacturers put in their systems; you'll see the peaks are in completely different places. I understand that people do get good results under HPS. My point is don't confuse the results of brute force with efficiency.

Well as long as you don't take offense, as I meant none.

Not yet, will look it up.

Ok... you lost me there again I'm talking about the most advance and most competitive greenhouse industry on planet earth (making the Netherlands with such a small area the second/third largest exporter of agricultural products after the US (and France depending on the source)). Companies like Gavita do a lot of scientific research without preconceived notions. The greenhouses in turn work closely with a reputable agriculture university. Like we established in the other thread, I don't know you, you seem like a good forummer at the very least, but honestly I can't help laughing a bit when you say "let's see your data" and then mock ceiling mounted lights in professional greenhouses.

So that's your data, that's the homework you've done? Peaks on graphs of LED manufacturers?

I think you confuse efficient power usage with growing cannabis efficiently.

I used to run 1x 600 in flower in a 4x4x6.5 tent (6 plants in 5 gal pots) and was very happy with my yeild. now I run 2x 600's in a 5x10x6.5 tent and are extremely!! happy with the yield (currently 12 plants in 3 gal pots, next cycle is 9 plants in 5 gal pots).

I even run an 8000btu portable a/c unit. I would like to go to 1000's, but I veg my plants for 2 months and after the stretch in flower they reach about 6'-6.5' and have to be tied down cause they are close to my hoods. plus the cost of a 1000w light vs a 600 is a bit more than id like, plus the added heat from the 2 1ks I would have in my room might not be controllable. im at a 73-77* lights on and 73* lights off currenty.

also going to run Ushio bulbs next change

Excellent. Same here-

And I still see it as an incredible waste of electricity. I'm using 40% of their watts per unit of growing area. That gives me the right to have that opinion.

So that's your data, that's the homework you've done? Peaks on graphs of LED manufacturers?

No, MY data is here with me. I suggested that as a quick way to look up online where LED mfrs use plant researchers' results in competitive products. There are plenty of places to research what constitutes plant active radiation and why. I'm comfortable that the more you learn about the subject, the more you will come to agree with my position. This is even more true considering the data you chose to use above to defend HPS as a good horticultural light source. Why? Because when I first looked into it, I followed your logic and reached the same conclusions. More research has led me here.

I think you confuse efficient power usage with growing cannabis efficiently.

Press explain this. It makes no sense to me, so clearly I'm not getting what you mean.

lol, come on, those look like some really quality parts there coc.. i could say leds aren't that expensive as well if i were to look for the biggest pos lights money could buy... i don't know too many people who would spend the money on that stuff, well, at least i wouldn't..

all i run are raw ballasts racer, only ever had one go bad (a 400w multi tap) in 8 years. i replace bulbs every six months.

never saw the point in paying an extra 100$ bucks for a pretty metal box...

Yeah, that's the deal I got on my last batch of HPS thouies. The ones sitting in boxes, waiting on the day the CDM experiment fails- or sold, if it succeeds.

My 860W CDM lamps run on the same magnetic ballast, just switch to the MH setting. Bulbs are $99 at;

http://advancedtechlighting.com/cdmea860.htm

This isn't terribly more expensive, and if the light is better then it's a big win! If it isn't better, the HPS bulbs go back in. My sunk costs amount to the bulbs and I can handle that.

yep, not bad... and if you're a spectrum lover, don't wire in the ignitor and you've got 1kw mh ballasts!

i lucked out on 24''x6'' pyrex cool tubes, 20$ each at an auction.

I like them wide open and easy to fix, nice! Can you buy an open kit for switchable? The circuitry difference is minor and would solve the flexibility problem.

you can easily wire in a switch with two small lengths of 12g or 14g wire. the ignitor is either connected or it isn't, and is only required to ignite the sodium gas. a mh will fire with the ignitor connected, but that will shorten the bulb life by around 40%

 

[Sativied]

Your logic used lumens- lumens are not for plants, they aren't a good yardstick for measuring PAR, or plant active response. Therefore, your logic was fatally flawed by bad assumptions from the beginning.

Speaking of flawed logic.... and bad assumptions. That underlined part may be some new discovery for you, it's nothing new to me. It's is also not the "logic" of the arguments I gave. You have avoided answering my question which was a lot more specific than just comparing lumens:

Since you insist, are you claiming the difference between that 95lm/w and 148lm/w is merely useless light [all in wrong part of spectrum]? Don't get me wrong, I'd love to use my watts more efficiently, but that seems a little exaggerated.

It's that simple question you avoided by redirecting me to your perception. If you've done so much homework and understand the graphs, I'd expect a more scientific answer.

The lumen maintenance on CDM is no worse than HPS, so that's a specious argument against the tech's relative merit.

Remember the thread where I quote this thread from? It sure doesn't look like that's the case. I haven't done my homework on this, I'm not "defending HPS" as a great horticulture light as you insinuate. You make these claims, the burden of proof is yours. If your bulb turns out to be better, I might actually buy it (literally as in purchase it, not as in believe )

I'm a friendly guy, but I'm tired of the challenging tone. I didn't kick down your plants, so be nice to me! If I challenge your assumptions I'm down for debate- but personal attacks are just immature.

Personal attacks? Because I challenge your hyped claims with facts and I have a hard time taking a side-by-side testing lighting efficiency in a stoner forum seriously...? If you look at my posts I kept it within a certain limit trying not to offend you. If you however prefer to discuss this riu-style... at least that way I get entertained. If you get upset from me challenging your claims and test using my usual honesty, don't quote me, you'd not be the first to regret it.

Press explain this. It makes no sense to me, so clearly I'm not getting what you mean.

My point was merely that if "brute force" leads to more cannabis from a given space, the amount of watt used or wasted isn't some goal by itself. Most growers don't start out with a given wattage limit but with a limited amount of space. If wasting 100watt of 150watt extra on useless spectrum means more yield from that given space, it wins regardless of its bruteforce method.

So let's get this straight, when you claim so scientifically "HPS spectrum sucks" what you really mean is HPS is inefficient (in a specific context...). The spectrum itself is rather 'complete'. Above all, you're comparing to one specific HPS right?

Brute Force is a great way of putting it. It kind of puts it into prospective.

I don't know? The 1k is only around $40 more a month at most, and I wont be in this shit hole 100 degree weather of southern California. I just think that going from 400 to 600 would be a let down in comparison to 400 to 1000. I might be blinded right now by it but the pro's of using a 600 to me don't seem to be more then the con's of a 1000.

Yes... I'd run 2 600s over 1 1000. I'd also run 3 600s over 2 1000s. I'm a firm believer in multiple points of light.

Exactly. If the same results can be achieved with less energy, then we'll be saving energy TWICE; once on the lighting, and again on hvac running costs.

I believe I've done this.
