Switching phal from Sphag to S/H - Are they ready to be repotted?

[scy]

After reading some of the posts in this forum, I have decided to switch to semi-hydroponics. I am very excited to give it a try after reading about how your orchids love it! I had some questions to ask before I got started. I just purchased two young phals, and they arrived potted in sphagnum moss. I've read on Ray's site and through the forums that it's important to repot into the s/h when there is active growth.

1. I've taken some photos of what I think are new roots. Would these two would be prime candidates for me to repot into s/h? If so, I plan on doing so asap. I have already purchased the material from First Ray's and prepared the medium as per the instructions provided.

2. If it is not ready to repotted:
a. How can I tell from the roots when it is ready for the switch?
b. How do I repot the sphagnum moss to make sure that it is not overpacked from the seller?
c. How do I water the sphag to make sure I do not drown it?

I just received the orchids 2 days ago. I am using a spray bottle to lightly spray the moss so that it is damp and not drenched. I am careful to avoid the crown and leaves. I do not think this is enough to get through the pot but am afraid to overwater. Sorry if my questions seem silly but I'm a newbie. Any help would be greatly appreciated! Thanks!

I only have two phals in s/h so I'm not qualified to comment on how to repot them. As to your other question on caring for the plants in sphagnum. I saturate the sphagnum completely, either by watering from the top or setting the pot in a saucer of water to water from the bottom. I don't water again until the pot feels very light and the top surface of the sphagnum is completely dry. In plastic pots with sphagnum that could take a week or more. Good luck with the switch to s/h. The phals I have in it are doing very well.

They look ready to repot into S/H. The new roots should adapt nicely.

Typically most new root growth occurs in the spring. I personally would wait for spring time growth, you never know what the new roots will do now that it is in a new growing environment. It could stop growing and then there wouldn't be anything left to try and adapt to the s/h culture and you would more then likely loose your current root system since it isn't adapted the the s/h culture.

Also, is it just one new root on each plant?

Here's a photo of the roots for one of them. Some of the longer roots have smaller roots starting to branch. However, the middle one has rotted, which is why I'm afraid of using sphrag.

1. Is this enough info to determine whether it can be repotted in s/h?
2. If it is not ready for s/h, I have no clue how to properly repot this in sphag. How do I pot it so that it's not too tight or too loose?

I suppose you could repot at this time, but as we're about to go through winter's dry air, you'll be risking keeping the root system too cool, unless you put the plant on a heat mat.

That tray you're standing them in is of no real value in boosting the %RH.

Ray and Becca are right.
It would be better in spring.

Well, my best advice for learning how to pot an orchid would be to try searching on YouTube for tips: Phal repoting - Google Search, and also repotme.com has video's on their website that might be helpful as well.

Thanks for the wonderful input everyone! I was going to make the switch to s/h, since I did see the new roots. However, since you all made valid points, I will wait until the Spring to try again.

As for the other phal, I didn't take pictures, but half of the roots rotted in the moss. There were more active root branches than the other one. I guess it's back to the dollar store tomorrow to find tiny clear containers to repot them.

Thanks Tucker & Becca for the tips on repotting and watering in sphag. I decided to mix it with bark in hopes of better drainage. I watched some very informative videos on youtube and repot me. I think I've been "too soft" on my orchids. I hold them so gently and cut carefully when the people in the videos just yank out leaves and cut away roots quickly without giving it another thought.

Oh just so I know for the Spring, how long do the new active roots have to be before they are ready for s/h? How many should there be before I attempt it?
