Let's just talk about BULBS!

it is not hate...there are NO leds that can even come close to hid...period...yes they are improving but are still very far off before feasible for anything but small scrogging
I'll agree that a single light source will out perform any multi-source fixture (CFL, T5, LED), but each has their purpose. Yes, I know there's a difference in performance, but they each serve a purpose. There's more to be said about the grower and their means, than about the lighting source. The sun is still the best option IMHO, but that's not an option every time.

... That being said, I'm finding it very difficult not to jump on the HID bandwagon, which is why I started reading this thread.

try multiple hid and wow!!!
I'm considering getting two dimmable ballasts, so I can run ~1KW continuously but effectively change the spectrum (one HPS and one MH) while the plants change cycles.

IE: 2X 600W ballasts, one at 50% through seedlings, and turn the second on (so 50:50) once they're well rooted. Then change the power to (MH:HPS, as the weeks/cycles pass) 75:50, 100:75, 75:100, switch to both HPS and run 100:100 to finish.

dude where are you getting this argon mh from?
http://www.monstergardens.com/index.php?page=shop.browse&category_id=63&vmcchk=1&option=com_virtuemart&Itemid=31

They sell both sulfur and the MH + Argon. So was a good comparison. Very few locations other than forums discuss the gas in the plasma.

http://www.youtube.com/watch?v=HFnaQqYDx_8 Video of the LEP in question: At 42 seconds, it details "Metal Halide & Argon Gas."

Maybe I'm reading their stuff wrong, or maybe they have this detailed incorrectly.

The -02 emitter has more red. See the bottom of this page: http://www.gavita-holland.com/index.php/products/gavita-power-line-high-performance-lighting/item/gavita-pro-300-lep-eu.html


I hope I'm reading all this correctly. I dig your posts and am sure not looking to argue. I'm in the learn mode.

I'll check it out. Not trying to argue either bro.

Yes it's the gas contained within but is still sulfur plasma as it is still sulfur that is the element which is super heated to a plasma state

I've sent a note to Monster gardens for clarification. There are two different emitters, and one emitter has two versions. And those two versions have significantly different spectrums. I'll pass along what I find.

I am not a Led grower ...the leds can hang with any hid light now..I have a few friends who grow with leds and the density n frost is there...just not cost efficient yet for large coverage....I see myself going all led in less than two years.

Just replaced my CHEAP China bulbs with a EYE Hortilux 600 super HPS bulb, and all i can say is WOW, it is so much bighter than the cheap bulb, it hurts my eyes to look in my grow room now, as before it was not that bright.

$20 bulb vs $120 bulb, no compition what so ever. Get the EYE hortilux bulbs, I can't belive that i ever grew with out this bulb.

Whew Yeah man I almost talked my self into going cheapo on a sunbright light or something named like that for 30 bucks less. Naw I think my gurls will love me long time if I just wait a few more days and stack up on Horti bulb. Thanks for the reassurance dude.

Nope. It's not sulfur plasma, indeed it is based on Metal Halides, not sulfur. Sulfur plasma lamps usually have large spinning balloons and are available mostly in very high output (usually >700W), which makes it very hard to distribute if you don't have much ceiling height. They are bulky, noisy and not solid state. The beauty of LEP by Luxim is that there are no moving parts. So yes it is plasma technology which gets it's wide spectrum from molecular emission (but not from sulfur but from metal halides, it has much more UV than sulfur plasma), is generated in an electrode-less cell heated by a tuned microwave (though stationary instead of rotating, and very small) and it also has a very long life. They call it LEP - Light Emitting Plasma. It is a sort of HID lamp (high intensity discharge lamp) but without electrodes and arc to heat the metal salts in the HPS/MH arc tube.

The HPS and MH lamps are based on atomic emission, not molecular emission. Every specific element has its specific emission line, specific colors in the spectrum. Sodium has a narrow transmission line you see really well in a low pressure sodium lamp. In a high pressure sodium lamp that spectrum is widened. So unlike plasma light (which is molecular) it is much more difficult to get a wide and even spectrum. Metal halides are a much better for spectrum but they lose material inside the arc tube so they tend to wear out fast and lack in color stability. Ceramic arc tubes don't permit those losses so they are much more stable in color and light maintenance.

Most LEP fixtures on the market use the LUXIM STA series emitter. There was (and still is) the STA 40 series, which is universal position (looks like a led in the center of the round puck) and there is the STA 41 series designed for pointing downward +/- 90 degrees (though we recommed +/- 60 degrees). It has a square puck and the cell is horizontally embedded. It has about 25% better efficiency than the STA 40 series. On the Gavita website you can find the two different spectra. Also check the whitepapers in the download section for for explanation about the spectra and the use of it supplemental light for HPS.

Thank you very much for your schooling. I admit my error and am very happy to have this factual knowledge. Thank you very much.For real.

yep...your name is accurate...you know whazzup!

I read alot of your words on ic as well. You are a gift to us all . Keep it up bro

I'm really thinking of using the Gavita -02 emitter and additional red LEDs as Bongjangles did (he had the -01 emitter). Even if yield suffered a bit. No heat is a big, big plus for me.

One guy here I talk to has pulled his LED I believe and said that it was very hard on some of his weaker strains he's growing. In fact, it damn near killed them, and stopped their growth totally. A couple of the strains seemed to like it. Hes now running his 600 Ushio instead.

I've seen a couple of bad ass grows here with LED though, one is amazing.

They've branded their newer metal-halide-bearing plasma sources LIFI, for "light fidelity". I got one and it burnt my plants. cn

I want to see it in action dude...I just spent a ton of money in the past years building my ultimate cabs and suckh a change over is completely feasible but I must say that it is rocking the worlsd growing yield and quality wise already

Here is a link to great (the best I have seen) deals on Kessil's:
http://www.krromastores.com/Kessil-H150-Magenta-LED-Grow-Light_p_10.html

I think that employing say four kessils and the plasma unit on a linear mover may prove BADDASS!! lol
