And to clarify, the DGC is the wise GURU not the Climb.

Hollow stems can be from lack of air flow, genetics also come into play, could also be older and getting close to harvest. I know a lot popular strains go hollow later. I have not tried cloning with a hollow stem, i would think if the pith was still there and nutrients can flow up and down, it could possibly root. I could be completely wrong, not a guru here, have 23 grows under my belt total, a novice by far. I am curious to see the other input. Happy growing!

Calcium! Gypsum and boron in my dry amends helped a ton with this. In order to pull off a good callus and thus a stable clean mom getting solid stems is important. In general not so much. Can follow slownickel on IG to see more examples of this. Seems allot of bro scientists aren’t up to date on this so idk how much info you’ll find on the web. I’ve heard some extremely smart and well seasoned growers that know far more than I, get this dead wrong.

Hollow stems will root fine and are fine for use for general stock, but a solid callus closes off the cut and ensures it doesn’t get infected once in the substrate.

I also boost my calcium a bit in the form of calcium chloride when I make my mixes from scratch using base salts. But gypsum is cheap and will add allot of strength to your base mix whether that be soil or coco. I’ve even heard of people using solution grade in hydro applications. Also wolla provides stronger cell walls and I believe an added kick of calcium also.

Normal plant physiology. As a plant gets bigger, the center hollows out; this provides greater strength as side branches get heavy.

Stem structure is genetic with some other influences of course. It’s not something to be very concerned with. I pay no mind to how hollow a stem is when cloning. Some plants grow tall and thin stems or grow short and thick stems. The opposite can occur with tall and thick stems or short and thin stems. I’ve seen it all.

Good episode. A lot of info Thanks for posting it.

<div>I recently came across an article by Annals of Botany and here is just the opening paragraph followed with a link to the article. The tests performed were done on tomatoes and not cannabis but it feels similar in production of flower.</div>

Pith autolysis, a condition in which dicotyledonous herbaceous plants have a hollow stem, results from the autolysis of a plant’s storage pith. Our central hypothesis concerning the aetiology of pith autolysis states that the carbon from the pith is transported to the growth regions of the plant and used at times when the plant cannot meet its carbon needs by photosynthesis alone.

this is great, thanks.

It’s plant fat. It’s actually baby fat. Very interesting.

Cut bigger branches off and gather clones from that. If you then submerge the whole branch and cut the slips off underwater…. you’ll sidestep the problem of getting an embolism in the stem that will end up looking totally fine for a day or so…. before completely shitting the bed and collapsing in a real flaccid manner.
