You both almost make me dance from good vibes lmao
I will just comment serrations because it’s vicious trait. You’re both right ^^
Consider the serration of leaves just like the hairiness of mammals, it’s the integrated AC of this plant. But powered with a “kompressor” (mercedes) :
- when the “kompressor” is at max pressure : phototropism at ~30° angle in direction of the sky and you can imagine the “sap/evap/stomates” work like a kind of diffuser outputting by each single serration of the plant.
It’s a very high flow part and the only one part that manage photosynthesis + sap pressure regulation at a time. As fast/dense that the arterial system (main veins, in center). It’s partly why it’s the first sector that burn when the sap is too charged in minerals (yes, with “organic” too it’s possible). The pressure at these spots make the higher concentration in the plant, just by the flow. It’s a bit like a sink half blocked.
- when the “kompressor” is at lowest workable pressure : phototropism at ~30% in direction of the ground, the sap become “stagnant”. And it’s where is the trap of understanding. It’s not a rational expression just because a plant can’t move like a mammal : no lung to oxygenate the sap, no heart to make the sap move, no legs to move from the swamp. So it directly show the consequence and not the defense/reaction.
It’s not an excuse to be a maniac of the phototropism, this phenomenom slower when the flowers take the lead and most of the time become negative a long time at the start of the senescence (that can last months for some sativas or more generally seeded females).
It’s also one of the most sensible trait with epigenetics with the number of blades. Let’s share a bit of “strain science” : i selected in my round the NL5H female maintaining the most the 9 blades leaves shape, because it’s the sign that the DNA is used full throttle. Specially since June lol, RH here is swinging from 40% (i love) to 70%+ (i hate) within the day, sometimes for one week straight.
So you’re both right on serrations ^^
If you need more than my explanation for farmer/stoner, there is a paper that is very nice and enter more in details with a crazy experiment in bonus.
Tips : mastering dry cycles (and never call it “crop steering” or i whip you with a trunk of jack herer, dipped in Canna PK ^^), learn you everything you need to know in this plant about :
- sap pressure
- how to flower packed as fuck under 75% RH without any worry (but gnats raids ^^)
- leafs functions : serrations, phototropism, “pressure shape” (like funky in the lower leaves) and even nutes resilience.
- understanding why cannabis isn’t a water lily, and why it’s the first exportation product of Maroc from its arid valleys and also why it was the best plant tested at Tchernobyl (hemp + canna) to depollute soil and even why a farmer that make rotations with hemp have always a superior product (higher prices) with the regular crop (tomatoes, wheat …).
Simple how-to : Never fall in the measurement of the watering, it’s a trap that will make you dumb. Learn to “see” and learn to “feel” this tempo as first priority.
Dry your experimental plants (in veg, early = more genetic resilience) until you see the phototropism falling by this unique leverage.
The optimal window can be short and the weight of the medium frightening. Be strong, after twos or three failed watering in synchro … it enter in your farmer’s hands for lifetime. Not joking. It will make you sensible to the global shapes by an angle you don’t guessed. It’s sharpening you on epigenetics expressions too.
It’s why i trust only the weight of the whole (plant + medium) and nothing else for the water content, RH for me is just a setting of the ecosystem. So like say Charles, i adapt.
You’re both enough used now to understand that it’s absolutely not a trick to don’t over-water the plants, but to learn the sweet spot of canna. You can even use this concept to optimize a DWC, in regulating the level of the water in the container in function of the ambient RH. We’re talking about more that 25% gain in yield and it can be automated now ^^
