Good idea with the fish tank Sarah-louise, I might give that a go one day ... though I'd have to get rid of the fish!!

My grow has been interesting, the fastest growing plant has slowed considerably and showed up some burnt leaf tips which I have almost remedied. The mutant seedling has formed an interesting shape on the trunk, the lowest part is thin and there is a bulbous growth that forms into a thicker trunk leading to the rest of the plant. I'll take some pictures tomorrow if I get the chance. The picture below is from a few weeks ago, you can clearly see the bulb in the trunk. I didn't get a chance to remove the husk and it deformed the plant, the first leaves were very odd and you can see them under the bulb. It has also formed a triangular shape when viewed from above, normally you get opposing leaves and everything is symmetrical but this plant is quite different as you can see in the second picture with a comparison of another plant.

Cheers,
