Hi All. Wondering how any one else out there is growing hangianum. I have a few seedlings that I'm growing in coconut chips and a few that I have in S/H. They seem to be doing equally well under the fluorescent lights with weak, weekly feedings. They are also pretty slow growers. Any tips out there?
I'm also growing some hangianum hybrids and they are growing much faster than the species.

I don't have any experience growing them, but if you can get a copy of this March's issue of "Orchids" there is an article by Dr. Leonid Averonyov detailing the differences between emersonii and hangianum. This might give you some hints for culture.

Hi Ray.

Where did you get your plants from? I got one last weekend from an Alberta grower (for $20!), but would like to get a couple more so that I could cross unrealated plants when they flower, or at the very least anything but a selfing.

Send me a PM or contact me of list if you would like.

Thanks
Kyle

PS, I would also like any tips on growing this little guy. I've only had mine a week so I don't have any advice.

I also think that was a pretty good article by Averyanov. There is also good ecological info in his book on Slippers of Vietnam. Lots of limestone where these guys grow. So pH levels are generally >7.0, and additional Ca/Mg is often appreciated. I use oyster shell and limestone chips with my parvi's. Emersonii, and hangianum are found at lower elevations, and in less exposed areas than micranthum or armeniacum, so seasonal temp and light fluctuations are not as great as for the high elevation types.

At this point I haven't seen a parvi do anything fast.

Dear Ray, yes, seedlings of hangianum are a bit slow growing but they will speed up when they become medium size. Of course, hybrids of hangianum grow much faster than the origianl species. My niveum x hangianum are having buds now and my bellatulum x hangianum and delenatii x hangianum should be able to bloom next year. :D

Try to give them more water and you can water them as frequent as possible if your medium drainage is good ! Try to gradually increasing the light intensity when the seedlings get bigger.

Hope your seedlings can bloom for you very soon!

Yes, there is fast growing parvi ! vietnamense and delenatii !! :D

Thanks for the replies all. I have pretty hard water so I haven't been adding any calcium but I may try adding a bit of lime to the mix on the next repotting of the seedlings in coconut chips. :)
