    Default getting impatient with my orchid flasks

    So three weeks ago I flasked a bunch of orchid seeds. There is ZERO growth of anything in the flasks (woohoo! no fungus!) My irritation is in finding anywhere on the net about how long it will take for the seeds/spores to sprout. I understand that they will be in the flasks for a long time, but about when should I see something happening?

    What should be growing is:
    Dend unicum
    Dend aphyllum
    Cym "disney girl"
    Cym aloifolium
    Cym tracyanum
    Bulbo macranthum
    Coelogyne trinervis

    Everything seems good, the agar is firm, should be packed with nutrients, the light and temp are good, and no contamination. A bit unsure as to the age of the spores. Ordered from thialand and thought they may have been a bit old. At what point can I scrap them and start over?

    Den and Cym are not such species that easy to germinate, I have Den that not germinate until over one month.

    But there can be many reasons why they are not germinate. Did you see the seeds swelling, if they are swelling they may try to germinate. If you germinate with seeds that you bought, it could be those seeds have bad quality or the time of sterilizing the seeds is too long and kill them. But you can also buy a simple microscope (I bought one can magnify 40X) and you can check if the seeds have embryos before you flask them.

    It's better to germinate with seeds that be havested by yourself, then you know the time period of pollination and have a better idea of the seed quality plus you don't have to kill some seeds during the disinfection.

    Yup, generally the cymbs and dends are some of the easiest to grow, behind epidendrum and some of the terrestrials (which can germinate happily in your backyard). Perhaps some of the seed was bad quality? Or maybe the flasks have been contaminated in some way? Either way, to expect growth after 3 weeks is rather impatient, it needs time, and care. I sent some dendrobium seed off 12 months ago, and im due to get them back in june, with some decent growth going on. That is the sort of timeframe to look at for some growth. Not 3 weeks.

    As I'm in China there are many Cyb. here, but to germinate them with good quality seed still needs a couple of month. Since germinate the seeds is slow most people use tissue culture or the traditional way of spilting the bulb to propagate them.

    I have germinated Epidendrum nocturnum in the KC formula and got good results, they are about 8 month from now. You can control the seed quality if you harvest your own seed, I have bought another species of Epidendrum seeds which have much lower germination than my other species of Epi. and this may result from bad seeds quality.

    If the flasks are polluted it's easy to notice maybe there is mold on the top of vitro, the vitro become watery or you can see some stain on the vitro.

    Here in my area of north china is autumn and not too long winter will come, I'm afraid the tempature and humidity are not suitble for those seedings, so I will wait for a couple of month.

    And do you think 8-month growth for Epi. from seed to the size of this picture is too long, the main reason I think is I never add plant hormone for those seedings. What do you guys think adding plant hormone to boost the growth of orchid from seed?
