Up and coming 50 watt red 630nm for flower. I made the mistake of ordering the wrong LED driver. But It did work momentarily and this SOB is so bright that you wouldn't be able to look at it across the street at 12 noon. 2000 lums, Perfect for pc grow.
2000 lums may not seem that bright compared to HPS or MH. but consider this, 2000lums coming from the area about the size of a dime.

use these wavelengths for the best absorption coefficients...

for reds youre only going to want to use a higher wavelength targeted only at 640 or 660 nm for red... otherwise you're gonna miss the highest peaks on the spectral curve to get the most out of the peak chlorophylls b at 640 and chlorophyll a at 660...

For the blues it looks like you have picked a good wavelength of 455-460...

so if you can get a combined effort 4 wide spectrum 40 watt cfl's 2 2700k and then 2 6500k for the blend also those cfl's tend to have a broad spectrum of light in them and arent just "red" or "blue", then add in there 4 50 watt red led's that are intense enough to cover a 2x2 area with an even lux all around, and 4 50 watt blues of the same area then you should do just fine for about 4 plants in that area you have now, or about 200 watts for per plant ;)

if youre going to keep the plant small however, and you dont really care about getting more than a 10 "dimes" out of a plant then keep it the way it is... ;)

But... by adding a glossy EVEN white reflective surface beneath and all around you will highly increase the effectiveness of the little room and little light that you have available and you will definitely increase your yield... tremendously... all of that metallic reflective surface is bent and curved and is, as of what the picture looks like, is pretty much useless to you and your plant, other than creating hot spots on your plants and doing really nothing to increase reflectivity to your plant as a whole...

i only say these things to help so please dont take it as me being an ass lol ;)

also be sure to check the diameter of the focal point of lux for your led's to make sure that its intensity is spread out on an even parabolic curve, otherwise you may only be giving an area of a dime on your plant the intensity needed for good growth ;)

I have done a lot of studies on this. There is significant debate concerning the peak grow and colors there in. I have read that 630nm is the best and 660nm. But here's is my conclusion thus far and I haven't come to any final conclusion as of yet.
When we humans see a rainbow, we not only observe a prism but we also see first hand the entire color spectrum visible by the naked eye. When we observe red, we see a nanometer spectrum between 600NM to 700NM. Anything between this wavelength would be a visible red. The same would be said for blue from 440NM to 500NM. This said, red is red and blue is blue as we observe it. Now, you have sellers or proprietors of LED lights in particular that claim their LED is the best when wavelength is considered. Now consider the source. CHINA. This is where 99% of LED's (light emitting diodes) come from. Even more, you have sellers claiming that their grow lights are "6 band" or more. What does this mean? Well lets take red for example. They have placed 6 different red LED's into a housing from 600NM to 700NM and call it a 6 band grow light. This said, Red is Red. Beneficial? Sure thing!! Compared to the sun? NO fucking way! So If I decide to supplement my grow with 630NM red along with 2700K (RED) CFL's then only one thing can be said. "I am only adding on"..

24 hour update. I need to stop doing this but this shit is growing so fast that it needs to be notated. Also, I have included a soil grow sample for comparison. The only reason I have the second plant is because my roomy decidced to save it after I thought it was dead and transplanted it from a bubble ponics system into soil.. Who's ever heard of that?

Cannofibiss,
I really appreciate your input here! I REALLY REALLY DO! And it seems you may have diagnosed my plants and have found a remedy for me. THANK YOU! I will try the Epson salt asap!!! Please don't take my rant about the color spectrum personal. They don't sell 660nm red 50w chips! That said, please come back again!
Also, I have a tent coming.

well i had something typed out and riu relogged me in so it erased it lol oh well,

this is the condensed version ... and as you said it best... When we humans see a rainbow, we not only observe a prism but we also see first hand the entire color spectrum visible by the naked eye. When we observe red, we see a nanometer spectrum between 600NM to 700NM. Anything between this wavelength would be a visible red. The same would be said for blue from 440NM to 500NM. This said, red is red and blue is blue as we observe it. Now, you have sellers or proprietors of LED lights in particular that claim their LED is the best when wavelength is considered. Now consider the source. CHINA. This is where 99% of LED's (light emitting diodes) come from. Even more, you have sellers claiming that their grow lights are "6 band" or more.

that is correct that is what "humans" see and however that is not what the plants see, as i have seen first hand the experiments involved in the cellular compositional matrix and synthesis of chlorophyll react at a higher and more efficient rate and at those wavelengths it excites the plants plasmodesmatas which are microscopic channels that carry intracellular nutrients faster throughout the plant better and naturally a plant that carries info and nutes faster... grows faster ;)

about the led's try kessil they are made in the usa in cali and are a part of dicon fiberoptics and they make fiberoptics for and have a contract with Caltech for their LHC in which i should know ;) giving props to caltech there lol anyways...

they are awesome lights that are really dialed in and well worth the little extra price tag, and less effort than having to order inferior chinese parts and stuff that just may not be spreading out a high enough amount of the photon flux density for your plant to have good and normal growth...

and for only just 2 of the lights of theirs since they are high intensity and are 150w each and they should definitely be able to handle a couple of plants quite well...

as far as the nute burn your pH looks to be fine and you wont burn your plants with magnesium unless you dumped the entire carton of epsom in there lol ;)

but here is a chart for pH and nutrients and their absorption/lockout rates so you can see what your plant generally does best in, because not all strains are created equal when it comes down to it some plants just like it a little more acidic and some plants a little more alkaline so here is something that should be useful if you havent seen it yet on here it has helped many people dial in on their setups whether hydro or soil :)

oh and i promise you that if you remove the tinfoil and the other metallic surface surrounding your grow room right now, that the white reflective mylar spread evenly without crinkles... that surface type will make a huge difference :)

Here the video that got me thinking about different red spectrum's back in the day.
http://www.youtube.com/watch?v=Fh9oGroryoc

Cannofbliss. Thanks again for the help! This is a hobby more than anything AND I like to experiment. Shoot.. I might smoke up like once or twice a month when my anxiety gets too high. (War Vet) So I kind of like doing things in ways others might not have tried yet. In fact, Picked up a 100w HPS to throw into the mix once I put these into flower inside a much bigger tent. So ya, a lot of different types of light and I really don't know or will even pretend what the outcome will be. If I fuck up then I fuck up! I sure hope not!
But I can tell you this, it's real nice coming in here knowing that there are people like you as well as others that love to help!

hey alleywalker... anytime :) its always good to have a hobby and always great to experiment... glad to see the wonderful plant cannabis yet again help so many people :)

the scientist in me has to come out here after seeing the video lol... although that is an interesting video and as far as having seen them testing 4 plants and their outcomes of growth...

it is of course unfortunately inaccurate, first because it is a tomato plant and not cannabis ;) and secondly it is a comparison between 4 different plants... because each plant most likely has different genetics even two different seeds off of the same mother plant can grow at substantially different rates and thus is very difficult to gauge growth rates based upon different lights temperatures etc...

another factor in growth or accelerated growth can be attributed to one plant may have been an F1(first cross) hybrid and thus has more vigorous growth, and or many other factors are involved... and in order for the test to be even accurate for lets say just even tomatoes... it is best to test the actual reaction of the plant cells to any frequency of wavelength and see which one frequency changes the rate of photosynthesis to a higher level ;)

well anyways regardless of that... lol... like said before i am glad to see that you have benefited from cannabis like so many others and wish you the best of luck and you'll do fine... and enjoy the grow! :)

Talking with a few people in here, you are in fact a go to guy around here! As far as the pic, I think I am being impatient! But that ganja girl in your profile pic could satisfy me 2 times....
Thanks much for the words!

Lowered water temps with cardboard heat shield. Added mag and my little friend responds with greener leafs.
Noted odd growth at a stem base.
