First Roth flask

[NEslipper]

I just deflasked my first flask on Thursday (3/25) and it was some roth seedlings I'm very excited about. All the agar was washed off and they were potted up together, with the ones that fell off in a second compot. Mix is fine orchiata, perlite, and charcoal top-dressed with some sphagnum. Ambient humidity is ~70%, and they’re in bags that are partially open for venting, temps are ~21-24C, low light. My plan was to set them and forget them for about 10 years, but I did check on them today (3/28) and noticed some brown spots and leaf tip die-back. I cut off the brown portions and put cinnamon on the cut site, but I was wondering if this is a normal part of the adjustment period, or something I should be more concerned about?

I grow indoors, so I would prefer to not have to spray, although I do have some Physan if absolutely necessary. Thanks for your help!

They look great. I also cut away any browning leaves and treat with cinnamon. What is the cross?

The browning happens as they are adjusting to the new environment and I would keep an eye to see if the browning continues as it could turn to rot. Cutting it off and treating them with cinnamin is what I did when my roths seedling as well. What is the roth cross? Is it from Orchid Inn?

Looking perfect. What is the cross?

 

[NEslipper]

Thanks for the reassurances! At one week and things seemed to have stabilized, I haven’t cut off any browning in a few days. So far, no losses (fingers crossed). Cross is ‘Paradise City’ x ‘Dark Angel’. The plants came out-of-flask, so it was very easy to rinse them off and pot them up. Almost no leaf or root breakage, all-in-all a very positive experience! Hopefully, I’ll get some nice blooms in a decade or so...

I was awful tempted by that cross. Should be great.

How many seedlings? I think it is going to be a great cross and has a high potential!

 

[Ozpaph]

Excellent cross (i purchased some, too). They look good. No more 'cutting'.

Ditto. I have that cross also. Should be good

I’m here to enable, you should go for it!!

There’s about 28, I didn’t get an exact count. I’m very happy! My windowsills will be overflowing once these start to put on some size!

I agree they should be excellent, I’m really excited about this line of breeding. Thank you! How are yours doing?

 

[Ozpaph]

only slightly bigger than yours - a few weeks out of flask.

They are a good size. Survival rate should be much higher with bigger seedlings.

Just be carefully when watering the seedlings. If water if found on the leaf axil and the crown, use a piece of toilet paper to absorb the extra water so it will not form crown rot!

They look good!
Without orchid shows in Europe it is so hard to get a hand on such crosses...
...hope for next year...

UPDATE: It’s been a little over 2 months. No losses yet (fingers crossed)! Not a lot going on vegetatively, but when I was watering them today I did notice some nice new root growth. It’s warming up here as we head into early summer, so I’m hoping to see some explosive growth in the next few months.

 

[Justin]

One thing I have found is to feed roths out of flask very lightly (or not at all). NBS and BS plants can take a ton of feeding, but not out of flask.

 

[Ozpaph]

you are doing VERY well with those. Mine are a bit sad....

 

[richgarrison]

love to see those root tips! high 5!

Your baby Roths look good, but if you want “explosive growth”, you might try phrags.
