Awesome^ did you use any rooting hormone?

[happyconcacti]

I'm not 100% sure if I did or not. I have vague recollection, now that you ask, of using a tiny tiny amount of "super-thrive". I believe it has rooting hormones.

Has anyone played around with CO2 (carbon dioxide) and P. Viridis leaf propagation?

If I recall correctly, I read an academic article about propagating P. Viridis stems where they wrapped the stem in Sphagnum moss and a baggie. They breathed into the baggie so there would be carbon dioxide.

Also, oyster mushroom mycelium releases large amounts of CO2:

One study showed (Zadrazil, 1976) showed that nearly 50% of the carbon base in wheat straw is liberated as gaseous carbon dioxide in the course of its decomposition by Oyster mushrooms!

Paul Stamets, Growing Gourmet and Medicinal Mushrooms, pp64

So I have a big chunk of oyster mushroom mycelium in a bag and am considering putting some of it in my P. Viridis propagation chamber.

Thoughts?


Thank you,
Hcc

Here's a method that describes blowing into a propagation baggie for CO2:

Just keep them apart from another so the oyster mushroom mycelium doesn't get a chance to feed on your cuttings? In theory you should have gas exchange between the mycelia and the Psychotria, but whether or not that system will be balanced is an unknown. Sounds like you're in the works to creating a small ecosystem, I'd love to see how that progresses!

 plant photosynthesis (may be respiration) produces CO2 (thats something ive found out recently, i always thought plants only produce O2)

Either way, your idea sounds much cooler

Oyster mushrooms are saprophytic, meaning they only feed on dead or decaying matter. They are not parasitic like the infamous Honey mushroom.

Not trying to call you out or anything, but do you have a source to this information? Like a scientific article or something?

Um ill look but i just learned this the other day in plant sciences class

Although it may not appear like i learned it lol

Its a byproduct of photosynthesis


Im currently at a church show thing with my parents (uggh), so ill link something up in a bit

Edit: maybe it respiration, lol

I know its in my textbook, but thats at my house

"In respiration, plants (and animals) convert the sugars (photosynthates) back into energy for growth and other life processes (metabolic processes).  The chemical equation for respiration shows that the photosynthates are combined with oxygen releasing energy, carbon dioxide, and water.  A simple chemical equation for respiration is given below. Notice that the equation for respiration is the opposite of that for photosynthesis."

Ok, quick question. A couple of my p. viridises (viridi??) have sprouts from the leaf well above the soil line. Is that ok, or is it going to be a problem when they acclimate to normal humidity? Can I repot or something if it's an issue?

Wow that thing looks healthy! I'd just leave it as is, personally. If it's growing great why change anything?

Wow! That looks great!  Personally I would separate those plantlets, but I guess it all depends on prefference.

Thanks! When I got those leaves there were several stacked together and the main stems made impressions in the other leaves from pressure in the mail. Once they got going, they went crazy sprouting from those impressions. I guess it worked out similar to making small breaks at different points in the leaves?

I think I'll leave them alone for now, mostly because I'm nervous to damage them. If I have to change it up later, I'll need some advice from you guys.

[TBM]

Each of those sprouts above the soil line should have their own roots trying to reach the ground, I've had that happen a few times already, you can transplant the ones above soil and they shouldn't experience too much transplant shock. Simply wait for them to grow another set or two of leaves to get more strength and use the same soil mix the mother leaf is in and you should be fine The fewer leaves you allow them to grow before separating from the mother leaf, the slower it will grow from there (since it'll have less surface area for photosynthesis)

Excellent advice TBM, couldn't have said it better myself.
