    Growing orchids in water? There are some that do what is called "semi-hydro", but in water all the time? A few of us experimented with some phals in water awhile back, and while I'm not aware of what happened to the other's plants, eventually mine all rotted and died. I'm not sure i've heard of growing them that way as orchids are generally found growing on trees, rocks etc. May I ask where you found the idea?? See, orchid roots are not like normal plant roots, as they must have some airflow around their roots to keep them healthy. And while there is a method with the Vanda types where you fill a glass vase with water, after a few minutes soak you dump the water out. Perhaps someone else has successfully raised one this way, but if I were you i'd dump the water and find a nice bark mix sized according to what type of orchid you have.

    Orchid growing in water is very much possible, looks very fancy, but involves very different growth conditions. While you save time on watering, fertilizing etc, you may have other issues. So in general it is for advanced growers who completely understand the orchid root biology. I would also recommend what Connie already said, you can start up with semi hydro and gradually progress to a complete water set up. Here is a good thread on water culture to get you started.

    In case this thread is referring to SH, the answer is yes: there can be a weak fertilizer solution. I use about quarter to half strength in my SH culture, depending on the type of orchid, heavy or light feeders. If you're referring to full hydroponics I have read (not done myself) that special fertilizer solutions are used for orchids.

    i just began full water culture for my two phals. i havnt had a problem yet with rotten roots and i havnt heard of this issue happening because orchid roots adapt to their environment. thier roots will change to allow less water to absorb and more oxegen in the water to be absorbed. also algea that grows in the water helps with oxygen intake so there will be no problem. just as long as ALL root rot / damaged roots are gone before placing them into water. if you dont remove it the problem will spread thus killing the plant as for fertilizer i use a very watered down solution

    I decided to try full water culture about a month ago and was amazed how it revives Phals.
    I had 2 Phals with no roots at all and now 1 has 2 nice fat roots and a few more little ones starting.
    The other is just starting to root also.
    Here are a few pics.

    While this may be a good way to revive a plant as an alternative to sphag and bag, I have yet to see a thread where anyone has done this for more than a few months. I am referring to water culture, as opposed to s/h. If anyone knows of such a thread, please post a link, or if it is somewhere else on the web please send me a pm with the link!
