Green Maudiae type again -- growing from flask

[hardy]

It's the green Maudiae-type again, a big big weakness of mine I'll share their progress in this new thread.

These two flasks arrived few days ago through mail-order from Ching Hua, looking good.

First, I soaked the seedlings in diluted fertilizer and Liquinox B1 Start.

Separated and washed clean.

Compotted in sphagnum.

The smallest of the lot.

I mark the same clones with numbers

From the other flask:

It seems Ching Hua always puts 27 seedlings for the final replate! Spot on! :rollhappy:

Same as last time, I'm putting them in a fish tank, covered with cling wrap except for a small opening at the corner:

The lamp I am using:

I use the same lamp type as shown in this packaging (6500K compact fluorescent), but in the two-pronged 13-W model.

I am toying with the idea of carbon dioxide fertilization. Maybe a yeast culture in a small soda bottle put in the tank will work wonders? Anybody tried that before?

I will update how they're doing!

Good luck! I have a particular weakness for green Maudiae types, too!

Hardy, as you grow your paphs in sphagnum, do you keep them always wet, or you let the moss dry out a bit? TY

 

[SlipperKing]

Most interesting...update often please.

Beautiful Seedlings! Hopefully you give them a bit of air circulation with a small computer fan.

Thanks for the pictorial of your process. Those look great.

Ching Hua sent you 2 really nice flasks. The seedlings look great!! Thanks for showing us your set up!

 

[SlipperFan]

They look very healthy -- you'll do well.

 

[Justin]

huge flasklings! i agree you should add air ventilation.

 

[KyushuCalanthe]

Nice, fat seedlings! Good luck with them.

 

[NYEric]

THey look great. Good luck!

Wow.. are you planning on starting a Maudiae cut flower farm soon..? Great job...

 

[JeanLux]

Interesting pics and good job so far !!!! Jean

 

[hardy]

Thank you all!

Maudiae cut flower farm... :drool::drool: Sounds good hehe


To Biothanasis:

I water the moss until it's quite wet (about halfway to saturation), and then wait until it gets quite dry, i.e. just moist, until I water again.
I find it OK for certain types of paphs but not so for others. Maudiae will do fine.

Fantastic looking flasklings!!! They're in capable hands!

I'm in agreement, it helps to harden them off. Here's what's been working for me, there's a little 5" fan sitting about 2 ft away. I use the egg crate to allow circulation under the pots as well & keep water on the bottom for additional humidity.

Seems to me you're doing fine Hardy. Are you new to growing orchids ?

 

[hardy]

Thank you for the suggestions about air circulation. Actually even though they
are large seedlings, some are etiolated and the leaves somewhat thin, some
even with transparent spots or pitting on them. That's why I'm giving them
extra high humidity for the first few weeks. I'll see how they go from here.

Rose, may I ask what media are you using for the compots and seedlings? Do
you water them often? Bark and coconut husk chips are available here but I
haven't tried either of them.

Hi Shiva, I've been growing orchids for several years now, but still quite new to
growing paph from flask. :rollhappy:

Hi Hardy -
I use a fine seedling bark mix, it has a little perlite, charcoal & moss.
I water every 2-3 days. The aquarium is in a north window, I do supplement lighting, about 12-13 hours a day.

Nice setup Hardy. I use to use the yeast setup for acquatic plants.. It worked incredibly well. The plants would grow an inch or two every day. Each week I would have to prune a lot of the plants as they outgrew the tank.

Carbon dioxide fertilization..? How does that work..? I mean what's the rationale? Aren't plants efficient enough at absorbing CO2 from the atmosphere without the need for an external source?
