This is a discussion on experimenting with flasking media within the Flasking Equipment & Technique forums, part of the Orchid Propagation category; Originally Posted by coeruleo what an amazing thread. i've wanted to try this myself, but ...
i do not know which media is the best but was told by fellow members of the forum that p668 works for most orchids so i decided to try with this. moreover i think it is one of the cheapest around.
well, here it goes. my first replatting. but at the mid of doing it, my back is killing me and i was asking why am i doing this and also i will be thinking no more flasking for me!
but looking back （the second and the third photo) on the final result.........hehe...i think i might do it again!!! haha
but i was so tired in the mid of it that i think i broke sterility....keeping my finger cross here
Look very neat, plenty of babies coming up.
Your seedlings will grow leaves initially, before roots. The roots will come in about 2 months or so after germination.
Commercial bought media is normally PH balanced and should work fine in most cases. As said earlier, some are more effective on different genera.
But there is commercial seed germination media too.
If you are going to get contamination, you would normally see if within the first week.
As for sugars, Potato grows roots, and banana grows leaves, while Coconut proliferates. You shouldn't have to worry about any of them with commercial media's.
thank you so much everyone for the info, i had learn so much from here.
more updates after the replating
Look good, Ian. They soon will produce leaves.
Just bear in mind that banana inhibits germination. You can also add some peptones for terrestrials and Paphipoedilum . Agar should be around 6-12 mg/litre. Best of luck !!

Why not add some activated charcoal ? It binds a lot off minerals .
the media P668 i used had the activated charcoal inside, so far the results are consistent for my catasetums, very pleased with the results. i only add about 60g of banana per liter of the P668 media to make it into replatting medium.
also experimented on two flask with low germination rate (only one to two protocorns per flask) to not replate them. just wanna see how well can they develop with only P668 alone. so far they produce longer shoots and less leaves.
