Right, ive decided to put my basic electronic skills to the test and have grabbed my soldering iron ready for this project.

I am going to implement LED growlights in my full tower stealth pc box which is currently in production too. I will also be using a diy bubble hydro setup in this as well.

Ok so ive found a great company that has a uk branch (digikey) for me to purchase LED's from. I know that the range needs to be red 630, blue 430 but finding led's that are exactly this is proving difficult.

So far I have found this on the digikey website

R1: Part# 365-1182-ND
5000mcd each

If anyone has a good supplier for LED's at cheap prices that deliver to the UK, I would be very gratefull if you could let me know.

thank you

sounds like a hell of a chalange good luck mate

Hehe yeah, w/e should be fun

Ok guys tell me what you think of this for the red led

Super RED 624~630mn, 6000 to 120000mcd, 2 to 2.6v

US$ 0.148 per unit

Good luck, making them yourself is the cheapest and its easy, good job

Sir,

Before you waste the money on the inferior LEDs the high wattage LEDs (over 1.5 amp a piece, under 1.5 amp will not work without more LEDs) produce enough light within 12" of the plant to grow if you have the correct color and enough of the correct amperage. To get your plants to flower better you will need a source of infrared light in the room, a CFL will work.

Go to the sites that suggestively sell their lights and look at their wavelenghts (something like 450nm and 650nm respectively for red/blue), go to an electronics site like digikey.com and order yourself some highwattage LEDs in the same wavelength. Order enough to build one panel 2 blue per 1 red and another panel that is 3 red per 1 blue.

Use your 2 blue per 1 red panel for veg and add the other panel for flower.

This will not be cheap as the right LEDs cost $4-5 a peice last time I checked and you will need hundreds as well as patience and soldering supplies.

For a 12v power supply I used a laptop power supply for my last try. It will produce buds and veg well for less wattage but you should still think about adding supplemental lighting like a few warm white CFLs during flowering.

Without a doubt, the most knowledgeable people I have ever come across, in the field of "Experimental LED Growlights", are to be found at UK420, I think that's www.uk420.com or maybe it was .org? At least that was true a couple of years, or so, ago! There were a couple of guys on there that would just blow your mind, I mean they really knew this shit, inside and out!

Believe me, there is a lot more to it then just using 2 wavelengths (1 red and 1 blue). You need 4 wavelengthes just to satisfy Chlorophyl-A and Chorophyl-B, then there are several other critical pigments that depend on other wavelengths for thier photosynthesis. God, I wonder what those guys are up to these days? Maybe I'll go have a "look-see" too!

could anyone help me with some info on how to make an led panel for vegging?, like which material to use and how to connect up all the lives and the naturals, do you need any resistors or anything?

You will need resistors and heat sinks if you get the high wattage LEDs. There is a bunch of planning involved in an electronic device of this type. I recommend you study the wavelength of the sun at the spring equinox and get the right kinds of LEDs to exactly replicate from the ultra violets to the infrared.

LEDs have an anode and a cathode to mark the flow of direction of electricity. If you do the research to determine what kind of LEDs you would like to use, then post it up I will look it over and design a circuit that will work on a laptop power supply.

I recommend mouser.com or digikey.com and select only higher wattage LEDs. They are expensive, in reality your light will end up costing close to the ones on eBay. Buy in bulk and you will get a better cost break obviously.

Good luck!

would theses ones work?
