Ciao Jean Pierre
you're a very luky man because I must try to grow them under artificial light and it's very difficult for me to understand which kind of light to use, for how many hours, etc.
This is my germinating box:
the flasks are under a flourescent tube (10.000°k) for 12 hours a day and the temperature is fixed at 25° C.
I use 2 differen media brought by OSP (W 2,5 and P669).
Actually I'm able to let my seeds to germinate but when I see the protocorms going green after few week they become of creamy colour and the growing stop.
I'm not able to understand where is the error (maybe because the flasks are hermetic and there's no oxigen interchange?).
What you believe it happens?
Ciao
