    use eye protection around your lights

    Absolutely.. blue LEDs are MUCH more harmful than the sun in regards to your eyes. Not even questionable. http://www.livescience.com/31949-led-lights-eye-damage.html http://www.cclvi.org/contributions/effects1.htm http://vision.about.com/od/sportsvision/a/Blue-Light-Exposure.htm...

    Jimjim's new diy 'creeation'

    Are you going to fill in the missing spectrums between 475nm-525nm that are important for carotenoids?

    New light test and first grow

    I used to just go to the local grocery store and buy RO water from the dispensers for 25 cents a gallon before I got my own RO/DI filter.

    PPM Rising Extremely Fast

    I use RO/DI and have the opposite problem, pH always drops. It goes from 6.2 down to 5.6 in 24 hours, then I add 50-60 drops of pH Up to get it back up to 6.2 in a 35G res. Going off what you have said.. my first question is, what type of PPM meter are you using? I have had the cheap $13...

    High Humidity At Night - DIY (Do It Yourself) Solution?

    What size/cfm extraction fan are you using? I am using 4 'PC' fans in line of my 6" ducting (had to cut the corners off the fans to make them fit). They push 155cfm ea @ 12v but are a little noisy at that power so I tone them down by putting them at 9v and they still seem to push 100-125cfm ea...

    First time DIY LED grow

    Day 44 of Flower. Few 'red' pictures from today and a picture of the power consumption for the entire closet with all lights and fans on.

    Hear Ye- Hear Ye LED Tubes + HH Spray 2.0 + BrandX Seeds

    I already have that with some of my lights I have made.. I use a 'Reef Angel' controller to control everything, or use a Typhoon controller to just control lighting schedules/intensities. Oops, sorry, didn't realize I was on page 1 when I hit reply. ;)

    The 'Shimmer' Experiment

    I just got done staring at leaves in a box for the last couple hours... even with strong wind, which does provide its own shimmer, doesn't get high intensities of light to certain parts of the leaf. If the shimmer idea works, it would put pulses of high intensity light to parts that would...

    A Curved Shaped LED Light

    I can't see your attachments. EDIT: now I see them, thanks! I just used the Blackdog graph because it was a nice graph. If you have another light graph that is better I will use that instead. I am actually trying to match a 1000w HPS in PAR output on a 4x4 grid. I don't think I can quite reach...

    A Curved Shaped LED Light

    I completely understand where your coming from... and my claims are 'way out there', I understand and agree with that. I just spent another $180 yesterday to 'refine' my light a little better (adding Cyan, few more warm whites, 475nm blues, in place of some of the reds so that the wattage is...

    The 'Shimmer' Experiment

    Excellent idea! I will have to try that one out. As for the 'why', it is the same answer to why someone would use a light mover. http://www.lightrail3.com/maximizing-your-grow-lights-potential/

    The 'Shimmer' Experiment

    After some more brainstorming I have come up with this idea... Instead of trying to slosh water around to creates waves, which would be a lot of weight over a 4'x2' area (size of the light I made), even 1/8" deep. All I really need to do is section off the glass and simply put a few drops of...

    First time DIY LED grow

    Updated pics.. Veg side... 4 of them are over 2' tall already, vegging way to long but they should weave very nicely in the screen for the next scrog. All different strains. 3 are going into the next round... not sure what to do with the 4th. There is XXX OG in the front, Headband in the back...

    The 'Shimmer' Experiment

    Thanks for the ideas! That is exactly the type of alternate thinking I was looking for! If I could get lasers like that article mentions that would definitely be much better than my ideas, but today there are 2 problems with that, 1. They (digital pattern changing lasers) are still very...

    The 'Shimmer' Experiment

    The defocused areas would be akin to LEDs without optics. It is more 'spreading the light' vs reflecting the light, but reflection is a big concern of mine. Think of it like placing a prism in front of the light and alternating the prism so it either focuses or spreads out the light. The hope is...

    The 'Shimmer' Experiment

    I am brainstorming some ideas on how to increase efficiency of LED light by using the 'shimmer effect' that is found in nature/ocean. Before the invention of high output LEDs, duplicating nature to do this effect was simply cosmetic and didn't provide the same benefits of nature (MH, while a...

    90W homemade LED grow

    The XPG is tried and true... the XTE with its silicon carbide substrate is still too new for my taste. It is probably fine, but I am still giving it a little time before I jump on board. First version of any new technology is bound to have a few bugs and from what I have read the new substrate...
