I build and set up a box, seperated in 4 sections. Each section containing one 1 Watt LED to support the inhabitants with light. The boxes have fans, so the air inside will be interchanged from time to time. To control the amount and - for the first experiment - the duration of the light and the fans i wrote a little script that is running on an arduino. This script also counts the time (and in case of a powerdrain stores this information on the eeprom). | I build and set up a box, seperated in 4 sections.

The LED are suspended from the top of the box using some bend metal strips, which simply clamp the star platine of the leds in place. Therefor i was able to adjust the space between LED and Pots to my liking, plus i didn't have to use any additional heatsink, as the LED were completely surrounded by air. | ||
For the first part I did not do controlled watering, i just gave them water by hand. | For the first part I did not do controlled watering, i just gave them water by hand. | ||
