So again its a week over. Oh no. 2 weeks. So Ill give 2.5g Calcinit, 1.2g epsom salt and 0.4g salt. Adjust ph to 6.0 later.
Cannabis hasnt really grown but its a calcium plant according to Kervran.
In Kervran’s classification, “silicon plants” are species whose ash contains a high proportion of silicon and whose physiology shows a strong tendency to use silicon as a starting point for elemental transformations. According to him, these plants consume calcium rather than accumulate it, tolerate sodium well, and can continue growing even when potassium is low. Their characteristic reaction is Si + C → Ca, meaning silicon is the primary “source element” and calcium the “product element.” Tomatoes are his main example: they accumulate silicon, draw calcium from the medium, and remain functional under sodium‑rich, potassium‑poor conditions.
They also do Na+O->K.
“Calcium plants,” in contrast, are species whose ash is dominated by calcium and which, in Kervran’s view, actively accumulate calcium during growth. These plants require high potassium, are sensitive to sodium, and cannot compensate for potassium deficiency. Their characteristic reactions are K + H → Ca and also Si + C → Ca, but calcium is the defining end‑element rather than silicon. Rice is his prime example: it builds up large amounts of calcium in seedlings, depends heavily on potassium, and collapses under sodium substitution. In Kervran’s system, silicon plants are flexible and sodium‑tolerant, while calcium plants are rigid, potassium‑dependent, and sodium‑intolerant.
K + H → Ca is in fact a bacteria reaction not performed by teh plant itself.
So Id need a different nutrient solution to test cannabis. But it has never been tested, who knows.
