It is under processing of cactus seeds germination.
I use 2 heating pans for the germination and so I can process anytime through a year.
I can set 18 of 10 cm square pots at a batch.
The current one is the 3rd batch in this season.
I sowed seeds on 5th of this month and some of them have been germinated already.
The photo is Discocactus horstii.
I was a bit worried about the freshness of seeds because these seeds were harvested in 2012.
It seems alright, showing a good germination rate.
