I hadnt made any updates here because lack of time, but the bucket have changed a lot.

Finally, assembled first prototype for the circuit board, already i have lot of changes in mind, but at least it took out a lot of cables and mess. Heres a shot:

Basically, powers 2 12v fans for the air flow and one to cool the leds, also uses has 2x 12V 6A relays to switch on and off the power to the main and side lights(also added them to the bucket) and has a connection for the water pump(which is still in development). Takes the power from a sauvaged 12V Wall power source and everithing is turned on and off by transistors controlled from the arduino.

Im now trying to develop a second model with a lot lot of updates, to make it even easier and more functional.

Othe major development was the redesign of the bucket. The top leafs where getting burned, so i decided to add more space vertically, i did a little sketch about it:

I did a little base with sauvaged pine wood from a matress:

and it turned out pretty well alltogether:

The air is flowing pretty well just with the 2x top fans and two passive intakes at bottom, also i added SMD 3560 as side lights, powered by 12V 1A wall power sources i had at home, and they turned to work pretty well, as some lower zones of the plant were getting very little light and this helped to develop that parts.
