nice quality work:thumbsup:

Hopefully this week or next ,I will beable too grab a few LEDS
and get a Tetra and make one with pics

Ya,, I thought it needed too be in its own thread as physics already has 2 projects going in his thread

Veggi,
Sorry about absence. I was interrupted by reality and had to take care of some business.
I hope to be finished by this weekend with the 660nm array. I had to back-track and screw mount some of the fans when I managed to dislodge them from the adhesive.
I am going to build the next strip in aluminum instead of copper. While the copper has much better thermal properties it is so darn hard to machine. It takes forever to tap a hole. You have to go really slow so they don't break.

hey redline I thought we lost ya!!!
I know how thats goes as i have been having troubles around the home my self. on the good side mouser got in the LEDS

I was lost, it happens to me way too often these days.

I have been rethinking some of the design criteria in order to get max yield using LEDs. I am going with a couple of basic assumptions (please feel free to challange) that will be cornerstone of designs:

1. LED plant projects need to be SCROGed for max yield. The flatter the better.
2. I am going to shoot for 30 watts per square foot, vs the standard 50 watt per square foot used for HPS. I think most of us will be happy with a 40% savings in lightbill (or footprint).
3. Goal will be to achieve .5 gram/watt/mo harvests.

4. While energy efficiency will be the numero uno criteria, costs also have to be kept under control, just to make projects affordable at our level.

Most of the commericial designs seem to be powerful 80 to 100 watt units on a small platform of between 1/2 to 1 square foot. I believe this concentrates the light too much.

I am now thinking smaller units between 10 to 30 watts that plug into
overhead motherboards that supply power and help duct heat. Motherboard would probably be about 2'x 2' aluminum and would provide up to 180 watts to supply LEDs and fans. There would be multiple plugs, so units could be custom positioned to fit needs of individual gardens. Also they could be repositioned as needed to accomodate different stages of growth.

This modular type design would also allow for upgrade designs in baby lights. Sort of a plug and play setup.

i think i would like the procyons LEDs a little more spaced as well....and you are right on the SOG/SCROG...i think If we did that this first grow, yeild wouldve been way higher...look out for LED-SOG thread in a few weeks!!!

Hey guys I was just thinking ,, we need a grow that crosses weedhound and stealth !!! :thumbsup:
