Maybe off topic, a tesco vase, plant clippings and a submersible light makes a nice lamp, its got a pond snail too. The plants manage to grow on daylight, they turn down a bit to the light at the bottom it its on for more than a few hours.
Its an aquaone mini aquarium light, I got it to see the nocturnal critters in the tank, but its a bit bright for that. I usually keep some plant trimmings in a vase, it looks really good and lasts a few months. Its funny having a snail in a lamp
