Lately in Thailand things have been VERY wet to say the least.... Flooding is amazing!!
The labs i use are all flooded at about 1 metre/3 feet and i cannot get my seedpods to them.....I'm forced to attempt germination rogerman style
Did you cut your seed pods well they're green? You could just let them brown and split. Use a coffee filter around the pod to keep everything together. Then, just let the seeds dry. They'll hold up for away being dried.
1.5 g/l NPK 20-20-20
20 g/l sugar
2 g activated charcoal (required with this type of species)
6 g/l agar agar
1 l demineralised water
for germination of these species this medium is fine, then when you transplanting into new medium, you can add 50 max 100 g / l of banana and raised to 2 g / l the NPK fertilizer
but if you want to buy a professional medium, you can use the Phytotec Lab P668 (half dose) or K400 or P723
