I'm pretty amazed at the moment about the rate the seedlings of bromfieldii v. glaudinae C382 are growing. They are only a little over a year old but show an appearance of an almost grown-up plant, long fissure and all. The largest plant is 1,6 cm with the others not far behind. Compared to only two or three weeks ago they've grown a lot. I was expecting to see such a development in lesliei v. mariae, but those just keep changing leaves without growing much. The reason could be the pure pumice (almost hydroponic) the seedlings are growing in, they probably need more food but I'd rather be careful with that.
