    I don't know about other "orchid food" that promotes root growth, perhaps you can tell us the brand and information so we can help you figure that out. Kelp Max is not so much a "food" as a stimulant for root growth and plant vitality. I ordered mine online, but since then I have seen it in a store that sells to organic gardeners and hydroponic type stuff. You might do an online search for hydroponic garden stores or something like that, maybe a local nursery. Big box stores probably won't carry it in a normal garden center. People have good luck with Superthrive too. I haven't tried it yet.

    I would not put them back in moss - the tightly packed moss method is designed for specific greenhouse growing circumstances and rarely works in the home. There isn't enough air, it doesn't dry out enough. I do use coarse bark with some sphagnum moss in it (maybe 1/4 of the mix) to keep some moisture at the roots. I do the moss because I tend to under water and it is very dry here. The roots you have now will not thrive under new conditions, they were adapted to the greenhouse and moss, however you can hope to support the plant until new roots grow that are adapted to your conditions.

    I don't know about leaving the roots above ground, but misting shouldn't get the foliage wet, just damp. Just mist the roots, a small amount on the leaves should dry right up. It might depend on your humidity, the time of day, air movement, etc.

    I would just add to what Carol said be patient, new roots might show up in a month or so, but they will .
    I have few phal in condition like yours. It took quite a few month to roots show up. I did tried sphag and bag method but it did not work so i left mine in regular home condituons, humidity on average 40-50% and temperature about 80F (it was summer). I misted root and foliage two to three times a day. And they was sitting above container with water. It took i would say about 2 months to start new root growth. Shortly after that new leaf showed up.
    So good luck with your phals!

    Thanks Carolla, I had only gone to the big box stores...I found "Miracle-Gro" Orchid food? Is this worth using?

    I had not even thought of the organic/hydroponic store here....I just called and they do not have KelpMax but, said they have some other Kelp based products. They do have Superthrive, so maybe I should just get some of that?

    I do believe the moss kept the root to damp because I have only water very sparingly.

    Thanks, Audrey

    Thanks Chemist....I had no idea it would take so long. I'll get these situated and then try to ignore them and wait for some root growth.

    I do have to similar plants that I put in a "nest" of sphag and hung on a wall hanging...they have done fine.....

    I also have two Big plants in sphag, that hang in a wire basket above my sink...the leaves are big...one leaf is over a foot long!

    Thanks for your help and everyones comments

    Small sprays wont hurt unless accompanied by extreme heat or cold as long as it doesn't collect in the center of the leaves. With the roots out of the soil however you could just mist the roots and not have to worry about the foliage at all. Wrapping in moss during this time should be okay if done loosely like with a mount but I would worry about constricting the roots to much right now and would suggest to not use it. This is the time when the roots getting plenty of air is vital and plays a major role in recovery. Obviously, nourishment is important too but that falls a close second.

    I have my Phals repotted again....after learning (from you good people) that my three smaller ones had root rot....I took all of mine out today and they all had started to rot. I know now that the tightly packed moss was the culpret....I hadn't watered too much but, the moss kept them wet for an extended amount of time and let no air to the roots. I gave all the roots a trim, then dunked in "Earth Kelp", then loosely potted back into a tiny bit of moss with bark, and styrophone pieces. I plan to mist the "soil" every 5 days to start with and see what happens. I do have some new root growth on my big plants so I'm hopeful. Thank you everyone!

    keep us posted on progress. I can't get "kelp" but a similar product called liquid seaweed. It has proven to be a great rescue tool.
