Awwwww yeahhhhh! I actually had green thai prawn curry yesterday :D Tonight im slow cooking a leg of lamb in coconut milk, probably do it massaman thai style :hump: :hump: :hump: Such a versatile and tasty ingredient, i get through several cans a week LOL

^^^ Fucking worrrrdd, i misread the dimensions and thought they were a tenth of their actual size, and the contacts would STILL be huge :P

Your pics arent working, Mont!

You are bang on the money my friend, thanks!

You dont need to use resistors in your LED design. You need Constant Current drivers. Read the stickies!

Would be really easy mate, you can pick up soldering tools for next to nothing, i bought 2 irons for around 7$ each, solder is cheap as chips, the most expensive part would be adhesive/heatsink compound and the heatsink itself. Ive never worked with those module type designs but they look like a...

Maybe some kind of watercooling device, or one of those ummm....i cant remember what theyre called....heat engines? the things where you pass a current through and one side heats up, the other cools down. What is the solution in commercial reflow? they just use a more suitable "base plate" ??

Heat causes trichs to amber faster, your CFLs are directing heat into the canopy and degrading trichromes (that is what is happening when they go brown). Interestingly monochromatic blue light especially (ie from your LED) can have a similar effect if it is too close to the plant, though that...

Basically, "lumens" are like...ok. so the human eye is better at seeing some colours than others. 555nanometre Green is the color we are best at seeing, and its like a smooth curve downwards as you go away from this wavelength (blue/violet on the left, yellow/red on the right). Lumens are a...

lumens are not very smart way of measuring light to plants - lumens, are a measurement of "what the human eye sees" which is very different from a plant. But you are right, LED are way more expensive. I would expect that 140W LED to shit on your 150w HPS, though

Coconut milk is for making curry you heathens :dunce:

Im still reading close Chroni, you narcissist!! :bigjoint:

your main limit here is budget. Do a single level and dont use all your height. I cant reccommend retail panels since i don't use them but some of the LED brotherhood will be able to help soon I am sure. :D

Except that thread is a year old, and so all those LEDs are obsolete my friend :D And what i meant by you need to do research is that, for example, while greensurfer might say those are the best LED for the money (or whatever), mr. X, Y , and Z might all think differently! If you are...

Nice man, you have been after a quick flowering grinspoon for ages if i remember right... :bigjoint:

Hehehe... :) You wont need a schematic as the simple way is constant current driver, hooked up in series with your LED that are on a heatsink. the question, then, is.... What LEDs? - What do plants like, what are the most efficient? Osram, CREE, and arguably Philips also, are the industry...

Yo Fran, You can get those EXACT diodes (from appearance at least) on dx.com. Theyre like 5$ for 20 or something like that. I have about 100 of them in various shades of white, red, and blue.

Dammit dolamic how many times, No sharing the contents of our FBI database with the suspects!! :dunce:

I would say you could take the same advice, was not my intention to flame but to share concern. Ive used oldschool whites on their own before, did a lot better with the spectrum filled out more (your RP's for example). vOv
