I'm sure you will, keep us posted please. I wouldn't worry that much since they are only 15w. I think it's more of a blending issue that will cause the burning you speak of. For instance, if corals that are grown in aquariums get way more red light then they should, they will start to "bleach...

I did the same thing. Bought a couple of 4' fixtures and now it makes it kinda hard to blend in other light sources. I'm seriously considering buying some more single bulb T5 fixtures so that I can blend in some other light sources. I really like T5 tubes for the fact that they put out such a...

Yeah, I'm talkin LEDs. They have a viewing angle of around 60 degrees, so that's why this guy took the reflectors off, probably not needed. T5's have a viewing angle of 360 degrees, so the reflector for them makes sense. You could always put the LEDs even with the tips of the T5 reflectors...

It looks like are using the same dense matrix type of led that Kessil is, only 15w instead of 36w. What's this lense that you speak of? I definitely might have to pick up a couple of these advanced led far-red spot lights to supplement with the 660nm Kessil if they even pan out. Thanks for...

That was probably the reason the guy at ledgrow.eu used the mylar around his grow area to give it a "tube effect." Although some light may get wasted without the individual reflectors directing the light in a beam like fashion towards the plant, its true that the light would blend quite a bit...

Here's that RGB analysis of the CMH bulb that you asked for the other day,

I've started to incorporate the UVb bulbs into both rooms now. On for 4 hours during the mid part of the light cycle. Got three new strains to work with. All cuttings from a dispensary from the L.A. I believe. I got them from a local friend here in CO. One cut is a blueberry #1, which I...

Oh ya, sorry, I wasn't knockin you by any means. I tried to make a couple educated and informative posts there and still like 3 pages later no one has responded yet. They are all into arguing over there.

You got it goin on bro! The overall color appearance of both your veg and flower mixtures look spot on! Nice work! I might have to copy what you are doing now! Real nice!

Don't bother checking out that CMH thread. There isn't one bit of information on CMH, it's just a bunch of people ranting back and forth calling each other names. Pointless really. I feel bad for the person who started the thread, they should really consider starting a new one now that one...

This thread officially SUCKS! I've posted 2 times now awaiting a response and it's as if no one has even bothered to read my posts! Would someone edit the name of this thread to, "a whole shit ton of ranting and no real information". That's all I have to say.

The only reason CMH bulbs appear white is because of all the green and yellow light that they emit. It's not going to harm the plants. Just add some pure red light to the mix and you are good to go.

Why did I even bother posting here? Add 150 watts of 660nm Red LEDs to your CMH and you have the perfect grow bulb.

http://www.lightpros.us.com/products-page/grow-lights/lp-400-400w-lamp/ Looking at the advertisement on ebay from this company, those amazing spectral analysis charts that I posted earlier ARE FROM LED grow lights not these induction lights! Why are they showing SPD graphs from HPS, MH and...

FOUND IT, http://www.ebay.com/itm/500w-induction-grow-light-full-spectrum-Tunnel-flood-replace-1000w-HPS-/220884521877?pt=LH_DefaultDomain_2&hash=item336dbe5395 Still hard to believe. Does anyone know anything about these? Looking at the ebay ad, I can tell straight up that this graph they...

I doubt those are accurate. Try looking up that info somewhere else for the same bulb. CFL'S usually emit light high in the yellow wavelengths the same as HPS do. I don't think they know what they're talking about. Misleading info there. What the heck is this? This doesn't look like the...

This thread is rather amusing. I've used HPS, MH blue, CMH, etc. etc. I will give you my real world results. From the tests I've done, I've found that not all strains prefer the same balance of wavelengths. Some prefer more blue heavy during veg, some more red heavy during veg. During...

Wow, I never realized that you would lose that much light from not having a parabolic reflector.

No, but I can do one. I'm sure it's equal Red Green Blue though. The CMH emits a pure white light.

I was reading about spectrum blending on that ledgrow.eu website. He said that he's taken the reflectors out for the same reason you just mentioned. He said the reflectors prevent spectrum blending at close distances so he took them out so they could blend more and get his plants closer to the...
