I have been trying out a number of flasking mediums and a few 'hybrid' versions as well. I have one medium which is showing fantastic potential, but has a nasty side effect, .... chlorosis of a high percentage of the germinating seedlings.
I have tried out around 15 mainstream media, and have resorted to hybridising existing and now adding a few spins to these.
Of the 'main-stream' media, my best results are currently with old fashioned M&S at half strength with adjusted micros and vitamins, plus coconut water and a 1/20 addition of Svante Malmgren medium. With this I am getting good germination of paphs and other species.
My new favourite is a mix using the above base with Tryptone substituted for the Peptone, and a liquidised endosperm of an African nut which is occurs on my farm. With this I am getting fantastic germination (glaucophylum, villosum and Maudiae are my current test subjects). The seedlings germinate around 5 weeks ahead of the same seed on 3 different mainstream media and show accelerated growth. The only downside is that 50% (of the bigger seedlings) are chlorotic. I replated the flasks to a general maintenance medium and a full strength version of the germinating medium, with adjusted NH4NO3.
My question is, .... does anyone have any experience with flask seedlings and them greening up? Is there some other adjustment that I can make? The seedlings are doing fantastically, only ice white! Predictably it is the biggest plants that are affected.
PLEASE any suggestions will be welcome!
