The first two crystals from Bilbao. We could call them B1 and B2, but I prefer to name them after the regions of Spain. Thus the little guy is Castilla and the bigger one is Leon. ;)
Unfortunately, Leon got a crack from the cooling, which I didn't expect since the growth temperature should be below 40° (just a guess) and thus close to room temperature. I need a solution for this.

Functiona!
The crystal is growing - slowly, but with good quality. Well, the upper part of the crystal is pure chaos, but the bottom port point towards the source is very acceptable. Thus the next growth will certainly result in a beautiful crystal. For that I need a nylon string which I was not able to organize up to now. Same for the almonds - I could not find 200g almond packages, yet.
To sum it up: The heat is on!

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...
