I haven't kept up on the LED's. I haven't seen any pro's boasting about their results either... It seems like it could be a good technology if the light spectrum could be pinned down but I don't think that's been done yet. IMHO I think this may have to do with the holes in the spectrum output of LED light units. For instance if your blue LED's cover 460-540nm and your reds pick up at 650-750nm you have a hole of no light in the 541-649nm range. With a MH or HPS you still have a little bit of everything and some colors are more concentrated than others but they are all there.
I think that the balance of colors that the bulb produces are something that an indoor gardener will fight forever. I have tried mixing MH and HPS in flower with varying results. I am quite interested in hanging CMH bulbs vertically as a supplement to the HPS but I have not had the funds to play with that idea yet. If Philips made the CMH in 600 or 1000 I would jump on them but until then it remains to be a luxury add on.
^^^
is there a difference in that as opposed to a separate 600w hps and 400w cmh?
would the intensity be better because it is a 1000w ballast?
im thinking of adding a 400w cmh to my 600w tent
I have always used 1000w Hortilux bulbs in the past, but this setup I decided to try a 400w CMH and a 600w HPS in a dual bulb hood, and I am extremely impressed with the veg growth I've seen this far. I'm starting flowering next week so the final evidence is still a few months off, but I am really confident this is going to be a great lighting setup.
Yup,I do it exactly the same way as you. Probably more like 10% bleach for me though.question for all you Colorado growers:
when you are in-between harvests; and you have the opportunity:
do you spray down your grow rooms with cleaning solution? or clean them in any way shape or form?
if so what do you use? how do you clean it out and get ready for the new stuff
im not talking about disposing of plants or anything like that just maintaining the actual grow room
i have heard to just use a 5% bleach 95% water solution and spray down the walls, floor and then let it dry out and you will be good to go is that correct?
i haven't seen any mold or powdery mildew in my grow area and id like to keep it that way
or is that overkill do i not even need to do that??
Hey Dorje I think you will be a bit disapointed when finish time comes around. I grow using a 600 and 400w Ceramic metal halide. they are inline and as aresult I dont get much cross spectral light. I can tell you from experience that the flowers WILL be leafier and you WILL yeild less. However the quality...is no better that I could tell. Just more trimming and less weight. I am swapping out the 400 for anoither 600. I hope in your case what I have seen is not true, but I have seen it in warehouses as well.Trying a horti blue (600HPS/400MH in same bulb) right now with a hot spot diffuser. Nicest light spectrum I've seen, but not quite as intense as the straight HPS. I think it'll improve quality, if not yield vs. the straight HPS.

Anybody got any info for some REAL fire in the Fort?

I'll save the blue for veg.... I agree the light intensity isn't as great but the diffuser mixes the spectrums a bit better.
Back to the original plan, supplement the 1 kW HPS with blue LEDs...
