Hi Richard, to me it looks like a 'Tricolor' that grew a green branch. The green branch is very interesting though with the line of color down the middle of some of the leaves. Typically variegation occurs like the rest of the plant with the green on the inside. I have never seen an obliqua with variegation like that!

Hi, Richard,

do you remember I have written already that

"sectorial and mericlinal chimeras can transform into each other under certain conditions."

http://forums.gardenweb.com/discussions/3241125/crassula-ovata-variegata-us-and-european-forms?n=67

Because they are very unstable chimeras. The colour of their leaves depends on chloroplast concentrations. It so happened that the leucoplasts have evolved into chloroplasts in the first layer of the leaves.
Therefore, we see the 'Tricolor' transformation into 'Solana'. In what conditions do you grow this plant?

hi Oks2n2

Some times I have trouble remembering where I was yesterday.

My wife says it sometimers, besides some of these big words are above my pay level.

I look them up and they seem to loose something in the translation.

I have had plants for many years but they never seemed to fascinate me until a couple of years ago, and now I am learning and appreciate your in knowledge along with everyone else here.

all my plants are grown inside in a green house environment.

Nice C. ovata obliqua 'Tricolor' with a green branch (or vice versa?). My green obliqua occasionally throws out a leaf with subtle variegation....which I promptly remove.

Josh

Wonderful greenhouse, Richard!

Richard,

Do you not have phyto-fixture by chance in your greenhouse?

Oksana.

And I can not translate this sentence:

"My wife says it sometimers, besides some of these big words are above my pay level."

Google-translator doesn't know the word "sometimers" :(

Hi Oksana

Sorry its American humor referring to Alzheimer's Disease where I cant remember certain things like birthdays but I can remember a woman's name from forty years ago.

above my pay scale means I haven't bin to school in fifty years and don't understand but I'm still learning.

no phyto-fixture only mother nature sunlight and a few t8 shop lights on the lower shelves.

Richard

Richard,

I'm 50 years too but I'm forced to study the biology basics now )))

What t8 lights do you use? Their characteristics?

hi Oksana

I didn't say I was fifty I said I haven't been to school in fifty years.

I'm 65 and retired.

bulbs are 4100k and 6500k which ever I can get for free I'm old and cheap

Richard

clear.

I know 6500K bulb's light promotes to greater synthesis of chlorophyll in the leaves. For comparison: the first ovata was grown under 6500K bulbs, the second was grown under bright LEDs, the third is 'Hummel's'

You have so much experience now with growing under different lights...is there any that you would strongly recommend? I am especially interested about your experience about LEDs.

Rina

Richard, what a splendid greenhouse ! Did you construct it yourself? I've never seen one so grand - I'd live in it myself.

HI Margaret

yes I laid every brick, did all the electrical and plumbing back in the early seventies.

it is what I did for almost 50 years as a storefront carpenter mostly glass and aluminum work.

it originally was set up as a bar and a Jacuzzi in the second room but converted for plants and an office about ten years ago. now I live amongst the cactus and succulents.it is an addition to my original house with another room as a den with a fireplace.

your answer to my crypto is wrong but I don't want to ruin the surprise.

Richard

Richard

If I may, a nosy question...how large is your green room?

Rina

HI Rina

the room with the sink is 12' x16' my office is12' x 12'

Richard

Well, I was never that bright at puzzles, Richard - correct answers always surprise me :)

Your greenhouse is amazing, it should be in one of those show magazines. Quite an achievement. Could you teach that work now you're retired, Richard?

It has rained and rained here for the past two days. Anyone want some?

I agree, great job on the Green room, Richard :-)

Josh

Hi Rina,

I have no specific advice on the LED use. But I rely on the study of the Soviet scientist Protasova in selection of the LEDs.

Oksana

Thank you for the link (now I really need to brush up on the Azbuka...)

Richard

Thank you, great room to spend time in.

Rina

Oksana, thanks for the article link, it was very interesting and helpful.

The following approximate conversion factor for w / m ^2 to umoles / m^2 / s was key in my understanding http://www.egc.com/useful_info_lighting.php .

Easy for you to say lol

anyone want to convert that to English.

Richard

Richard - Your workstation looks awesome! Having all that light and those plants all around must make for a great working environment. =)

Haha, even in English the paper is quite specific and technical! I used google translate and it did a pretty good job.

Much talk is using PAR w/m^2. In general, I would describe the light levels they used as:

• 500 - full sun all day (not extreme full sun).
• 410 - nearly full sun, as if your plants were slightly shaded at the hottest part of the day
• 325 - very bright shade
• 140 - shaded or bright indoor window that gets sun most of the day
• 50 - quite shaded if outdoors or indoor window that gets sun part of the day or is partially obstructed.

I would summarize their results state that 30% blue, 20% green, and 50% red is a good spectral distribution for growing plants. Skewing this ratio has different results, such as more chlorophyll, dwarfing, elongation, etc.

Notably, the vast majority of information and discussions (even in gardenweb forums) is filled with misinformation on lighting, particularly spectrum and intensity. Well supported studies like these are always a nice read!

ewwmayo

thank you for the link. But I prefer to consider only the spectral characteristics of the LED-fixture now. I wouldn't want to use other artificial light sources because of their energy intensity.

Oksana.

"...ownership of this plant rides in the balance..."

Sooooo....who got the plant?

tj

Hi tsugajunkie

I get to keep it with two votes for C. ovata obliqua 'Tricolor'

Richard

Congratulations Sir Richard!

"The following approximate conversion factor for w / m ^2 to umoles / m^2 / s was key in my understanding"

I'm in awe. I should have started running when Oksana mentioned that Soviet scientist Protasova.

Indoors, he says. I don't count that as growing indoors, lol.

especially not after my Haworthias get etoliated in one of my south facing windows!
