Inspecting some seeds

I have been playing with my camera lately and realised that it is somewhat more sensitive then the human eye. So, I have been taking a few pics of seeds in flask that I recently sowed to see if I could pic up any germination or swelling of embryos. I have included a few pics below just for fun.
The first image is of seeds sown of Phaius tankervilleae about 10 days ago. Already the embryos have started to swell which is good news. The second image is of Epidendrum radicans, also about 10 days old. Then, the little blurry green blobs are from seeds of a Coelogyne mooreana hybrid which I kindly received from Paul Zuijdam. I had to wait to sow these so they sat in the fridge for a bit until I replaced my HEPA filter recently. The last image if of swelling embryos of Eulophia streptopetala.

Dendrobium crystallinum babies

Dendrobium crystallinum is the latest addition to my seedling collection. I sowed the seeds on 3rd January this year and they germinated in 21 days at 26 Degrees Celsius. The species is from the Chinese Himalayas, Myanmar (Burma), Thailand, Laos, Cambodia and Vietnam according to the IOSPE website. It is considered a cool to warm growing medium sized epiphyte of small trees. The flowers are typically Dendrobium but are strikingly beautiful. The flowers are also fragrant. The seedlings are now 3 months old and are due for a re-plate now. Media used for sowing was my own modified recipe of P6668 with 30g added sucrose.
