Thanks, Mike. I really appreciate the support. The pictures and your description of your process are invaluable. I like sphagnum a lot. Some of my mature paphs are in it. Using it for small seedlings perfect sense to me.John
None of these little tigrinums have extensive roots and they grow slowly. So if the roots wither, then the plants lose leaves faster than they can grow them. If you put them into bark right out of the flask, they will wither. Sam commented to me that he was seeing excessive losses after the plants were deflasked. It looks like they need to reach a healthy size before they can go into anything other than moss, but growing them in moss is too tedious to do on his scale. I have been sharing photos of my growing experiments with him. Mike
Thanks! Yes, I'm resting the compots in an aluminum sheet pan, mainly to act as a drip tray. Adding the heating pad may or may not be necessary but if so, I think the pan would be an effective buffer. Delivery tomorrow. Sam recommends maybe waiting a day or two before deflasking and putting the flask in some gentle natural light, but keeping an eye out for mold.Inocucor isn’t available in the us anymore unfortunately. Putting any heat pad directly in contact underneath compote would be a great way to kill them . But something in between that can soak up some heat and release slowly and if possible some kind of thermostat would be good. Could even have a water reservoir directly underneath with an aquarium heater
just go for it!!! it's only money and you can always buy more and try again.I feel sure I'm going to make a mess out of the actual compotting. This is not my strong point. When sphagnum is used too loose, it's stays sodden and when it's too tight there's not much air space. And trying to be careful of these fragile little roots while getting the level and density just right, I'm not confident.
Great advice, Mike.Just keep in mind that some will die, and it is a good thing. The weak and the defective need to be weeded out. In my opinion, it is a waste of time trying to encourage the runts to hang on. No one has that much extra space. When you move them into fresh moss in 5-6 months, be aggressive culling the seedlings. Poor roots or yellow leaves, throw them away. Mike
Well, I didn't like the idea of a soggy environment in a non-sterile container. I feel better about this. The vent is closed, but there are drainage holes in the bottom that would let in some fresh humid air, in addition to the air that was inside the mini-greenhouse. I'm just thinking "balance". I'll Youtube how to actually get the plant/agar mass out of the flask. At this point, no idea. Duh. You're being very generous, Mike. Thank you.There is no need to vent the flask. The humidity inside will always be 100%. Sam typically opens the flask and puts in peanuts to protect from mechanical damage during shipment. If so, you need to pot these out in the next day or two, since the flask is no longer sterile. Remove any brown leaves, and if there were a lot of them, spray with fungicide. Just keep an eye on the new compots and you will be fine. Mike
Thanks. I guess because they seem happy in sphagnum. Not sure it's a good idea to move them to a different medium when they're still quite small. I don't know what kind of a root system they have at this point. Disturbing them at all is probably just my OCD kicking in. I'm interested in any suggestions you might have, though.they do look good. why keep in sphag?
I've been looking through some stuff, and did some quick web searches trying to find where I ordered these from. Thing is, I ordered two or three different styles. So it's a little confusing to remember what came from where. I have a stack of packing slips that I throw everything into. If I find the one for the compots with domes I'll post it. Thanks.Where did you find the clear compots/domes? Some have been trying to find some
Your plants look fine. Don't be afraid to look at the roots and replace the moss. The roots won't have root hairs at this stage. Please keep in mind that growing orchids from flask will require a lot of experience before you get consistently good results. You are going to spend a lot of money and a lot of plants are going to die. Also, you picked a species known to be difficult, so feel good about your results. I've had many flasks where I killed all of the plants.Thanks. I guess because they seem happy in sphagnum. Not sure it's a good idea to move them to a different medium when they're still quite small.
