Anyone have tips on watering? I've experimented a lot with phals, first finding out how easy it is to over water and rot the roots. So I decided to water once a week as that seemed to be when the bark would finally dry out all the way, but the leaves just wouldn't perk up all the way, which told me they were probably dehydrated. So then I tried bare roots, Hanging them up and heavily misting the roots twice a day, or when they turned silver. About 6 months of bare roots and they started growing some new leaves, even got a spike that didn't bloom, but the old leaves were still a bit shriveled/wrinkled, and the new leaves didn't grow much and weren't very firm. So, I put them back in bark, hoping it might hydrate them better, but I'm terrified of root rot lol. I now water them once a week, giving each one a 5-10 minute soak before putting it back on the rack and repeating a week later. They are potted in a clear plastic pot covered in holes for ventilation. Throughout this entire process, they've had consistent lighting and been fertilized 1-2 times a month, and never get water in the crown. I'm wondering if adding sphagnum moss might be a good idea to get it more hydrated without rotting the roots or jump starting that white mold stuff. Okay thats about it, all tips and ideas are welcome if anyone manages to read all of this! Pics attached were taken right before watering, this is as dry as they get.

    The great thing about clear planters is you can see when the roots turn silver in color and that’s when you know it’s time to water them! I’ve used sphagnum moss before but found it to be too water retentive. I prefer to keep mine in a chunky orchid bark mix and just water as soon as I see the that most of the roots have turned silver.

      When I first notice the roots looking silver and ready for water, the bark isnt completely dry so I usually wait another day or two for it to dry out (which is probably the reason for dehydration) because when I water it when the bark isnt totally dry, I usually get the white fuzzy mold stuff. I just can't find the perfect spot in between dehydration and root rot/mold!

      Hm, how big is the planter compared to the size of the roots? If its more than 2 inches bigger than the root ball, that might explain why the bark isn’t drying out completely. You could also try adding some chunky perlite and horticultural charcoal to the mix to increase aeration and help the bark dry out faster, or add a small fan for some increased airflow.

      Wow thats actually very helpful idk why I never thought of that! I'll probably try that thanks! I'd say there's about 1-2inches of bark at the bottom so wow yeah thanks for the revelation

    Sounds like you’re doing all the right things. All depends on your home environment. I soak mine once / wk for 15-20 min. Never fertilize @ full strength. It may be the lighting in your pics but the leaves appear “purple-ish” usually means not enough bright (diffused) light. Also, just because leaves are wrinkled doesn’t mean not enough water. This is one of mine about to bloom now with wrinkly leaves

      I have 3 sets of lights, the purple one for my african violets but since it has 4 light bars on it, 2 of them are over the orchids, but the light meter says 5740 lux, so yeah maybe I should invest in better lighting lol. Do you know why your leaves are wrinkled? The new growth looks good, but on my wrinkled orchids, the new growth is also a bit wrinkly. I forgot to include the fact that I'm now fertilizing lightly with each water now, using a quarter teaspoon of 20-14-13 fertilizer in a gallon of water for the flowerless orchids, and a quarter teaspoon of 10-30-20 in 1 gallon for the flowering ones.

    The current leaves are likely to stay wrinkly from past dehydration, so use new growth as a guide for what it needs. It looks like you've got new roots coming in, so I'd stick with the bark and watering once or twice a week. For the leaves, ideal is a smooth, bright apple green. The purple is a natural sunscreen that plants can make, so just a subtle flush of it at the very edges of the leaves indicates that it's getting plenty of light. More than that, and it's asking for less direct light (so same amount, just diffused). The older leaves show a lot of purple, so the too-direct light may have been part of why it stayed dehydrated. As for preventing rot, adjust your watering gradually, because stressed plants are the most vulnerable. It should recover well
