Mike's amboinensis

[mayres]

I got my species plants on Friday 3/28/08. On arrival day the plant looked like the following.
First hint of what I had to work with!

All unwrapped and ready to place under my cheapie shop lights for the time being until I get time to repot.

Okay - last Sunday I made the repot move. Unpotted my initial impression of this plant at this point can be summed up in one word (right or wrong) - FRAGILE.

Here is the same plant now put in coir mix. The outline of two of the leaves are just a touch yellow and make me a little nervous. I have all my fingers and toes crossed and am now waiting for warmer weather to kick in and give this baby a growing boost (today's cool snow, sleet, hail, rain, etc. was unbelievable - isn't this spring?).

Mike~ If you look at your arrival photo, you can see that the yellowing had already started a bit around the edges. The flash of the camera picked it up and heightened the yellowing.

[mayres]

Right you are about the yellowing Jenny. Hopefully it will not progress for awhile.......

[Sharyn]

Mike: Mine also had a slight bit of yellowing. The bottom leaf fell off and I was also a little nervous. One of the other leaves had a bit of yellowing at the edges, like yours. I repotted mine in the coir mix, and it's doing fine now.

I know you, Brookn, Connie, and I had some root issues.....

Is there anyone else that had not so impressive roots????

How much will this set the plants back on growth?

[made4engineering]

My roots were not spectacular either. I even cut some off that were still alive but dangling by a thread (you know the ones). Mine has been very vigorous since I mounted it though - everythings growing on it. I'll post pics after finals are over.

[mayres]

Well - as we all know, these orchids try our patience.....
After 38 days of living with me my little guy is finally showing signs of a new leaf! Except for one five day spell of very warm weather the rest of the days have been unseasonably cool - which I'm certain has not helped.

[patticake]

Isn't it great when that new little middle finally pops out? There's hope!!

[solay]

Mike, I'm with you about small orchids. They look so fragile. I keep knocking them over and spilling all the mix. Too small for my clumsy hands. It looks like your plant is showing signs of life. Good growing!

[articuno75]

Do you have it under more light along with the increased heat? My apartment stays around the 70s and mine hasn't budged.

[FLaCo]

Is it just me or are these seedlings taking forever!?

[mayres]

I have mine about two inches from cheapie shop lights. I'm thinking that whenever summer arrives the heat will make them grow (?) - we're not there yet! I believe they would prefer to be in the 80's or even low 90's for optimal growth conditions. Some of you may remember a link I gave early last year regarding advice for commercial phal growers - http://www.hrt.msu.edu/faculty/Runkl...20part%201.pdf.
Note the part in here about what temperature to ideally grow these young plants! If you are interested in reading the rest of the article just replace the "201" portion of the link with 202, 203, & 204 - it is a four parter.

Mike, sounds like you have the amboinensis much too close to the lights. Baker says 1000 to 1200 fc. My fluorescent lights are giving me 1500 fc at about a foot or more away. Remember, too much light will stress a Phal until some pathogen comes along and Kapow!, no more Phal. Mine are inexpensive growlights, but that changes the spectrum, not the intensity.

[sandra]

ooooh, nice growing Mike. Are you going to put this outside once the weather warms up?

My little ugly amboinensis's leaves have grown somewhat so now, every nick and cut is bigger and uglier.

I have a feeling I can ID the source by the tag. I have a few of these little species phals from the same vendour. The media they use is quite good. Wondering why the immediate repot? The plant is quite young; fragile indeed. The weather at the time you received the plant was cold. (still cold ) It may have gotten slightly chilled in shipment, even though well packed. I've never been in favour of repotting upon arrival. Truth be told, I don't repot unless it's absolutely necessary. It tends to set the plant back, especially after moving it to a new evironment. One of my "baby phals" hit the floor a time back. (similar to a repot IMO) Wasn't damaged but It hasn't been the same since. Same issue; lower leaf not looking too great. The ones that I did nothing to and let them settle in are in bloom and or growing new leaves.

I have these in slightly higher light 2000 fc's. I wouldn't go much above that while they are still small.

[mayres]

Cynthia, you must have much better quality light fixtures that I do. Even with brand new bulbs right up against them I only measure 1000 fc with my light meter. I grow all my phals as close to the bulbs as I can get them and the proof seems to be in the outcome - for two years now - nothing appears to be getting too much light. In fact, I believe I could use a little more - just a few inches away and reaching out to the ends I'm dropping off to 700-800 fc. This is what happens with $10 fixtures obtained from places like Lowe's and Home Depot. Now if you want to talk about my T5 fixture that is a COMPLETELY different story - that guy pumps out the rays! So far I have not tried any of my phals under it - though I have been tempted.

I'm curious what kind of bulbs Cynthia is using as well. I have 'full specturm' bulbs in cheapie shop lights and I'm lucky to get 1000 fc two inches above the leaves also.

[Cynthia, Prescott, AZ]

Yep, you're right Mike. I have to learn to use my light meter better. I just lowered the fixture, but still too few fc. Need to carry out my original plan of using mylar to shroud the plants to pick up a few extra fc. Have a single T5 fixture I may add.
