Having played around with growing plants under LED lights before, I thought I'd have a go at building a larger system using high power LED's.
........ I do apologise if it looks like I'm flogging a dead horse, this will be my last instructable on growing things with LED's.....honest.
I haven't found any commercial units that use high power LED's (then again i haven't really looked, and I like to maintain the illusion I'm being original :) ), so i figure this is probably different enough from my other attempts to be worth posting.
I probably better say that you really shouldn't be attempting this unless you have a sound knowledge of electronics and have experience working with mains electricity. Also there will be high voltage near a damp environment, which is generally not the best of ideas.
It also uses really bright light, and can probably do nasty things to your eyes if you stare at it, then again if you can read this you probably don't spend so much time staring at the sun/bright objects, so hopefully common sense will prevail.
Basically be safe, and don't attempt this unless you are positive you know exactly what you are doing.
Step 1: Parts
Here's what you'll be needing:
1x Large Tub.
1x High current 5v/10v supply.
4x 3w high power red LED.
1x 3w high power blue LED.
2x STP36NF06L MOSFET.
2x 100K 0.25W resistor.
2x 0.47R 3W resistor.
1x Aluminium Box.
1x Mains Lead.
