No functiona :-(

Up to now it does not work :-( Maybe I have to try a stronger bulb? If until tomorrow no crystals grow I will change the setup. In the future I also want to try a reversed temperature gradient, that means at the top of the  container is the hot side and at the bottom the cold side. This will require some changes of the interior of the container for depositing the source material in some way.

It goes on ...

I spent 15€ on a lamp and some bulbs. Setting up the temperature gradient... up to now it does not work. I will grow some seeds. I have the feeling, the convection is somehow not strong enough to reach a sufficient supersaturation for nucleation. I couldnot observe homogeneous nuclation so far...
