electric grow bottle

electric grow bottle

As a kid, me, my brother and my mum used to make bottle gardens, the idea was to plant a load of plants in a bottle only through the neck (think of those ships in a bottle).
Anyway i was thinking of building an update to this:http://www.instructables.com/id/Growing-Plants-With-LED-Lights/ when i got bored and thought i'd put together an electric bottle garden in old water bottle i had lying around.

Although this is kinda similar to my other instructable i figure its different enough to be worth posting. Its also not really an entirely sensible project, loads of light leaks out the sides (but it looks pretty) so its more of an LED assisted bottle garden, and it would of been a hell of a load easier to just cut up the bottle, but i liked the idea of doing it just through the neck.

Passo 1: building the lighting rig

I wanted to fit everything through the neck of the bottle, and i also wanted the LED's to cover as much of the soil as possible. So i figured some kind of expandable lighting rig that would fit through the neck of the bottle was the way to go.

To do this you'll need:
12 red LED's
1 blue LED
a square bit of plastic
thick copper wire
13 220ohm resistors
wire

you should also have a fair bit of experience soldering and making electrical circuits.

Firstly solder 3 LED's along a piece of copper wire at about one inch intervals, making sure they are all soldered the same way around.
