So, first off some observations:
I used to drink a lot of coffee. More than 2 litres per day of strong drip brew. I loved the way it tasted and how it made me feel. I loved the ritual of preparation. I idolized James Hoffman... I was an addict.
But, just like many other drugs, there are diminished returns: Eventually, rather than having a pleasant euphoric rush, I was just trying to get back to feeling 'normal' by drinking another cup, and another cup, and another.
My sleep was suffering- to put it mildly, my psoriasis was getting bad, and mostly I just felt 'sludgy' most of the time.
Simultaneously, I was starting to read Sol Viva and Anna Edey's experiments with using dilute urine "Urine Charge" as a fertilizer. This made sense to me so I decided to give it a shot in my gardens.
Of note: The piss I was producing had a strong odour. Not hugely unpleasant, but it had a distinct roasted coffee bean smell. Of course this smell was the metabolized remnants of all that coffee filtered through my kidneys...
And the plants loved it! faster and higher germination, hardening off quickly, producing lots of foliage and in most cases fruit.
I haven't entirely quit coffee. I maybe drink 1 cup every week or less. I do sometimes drink tea. But I've reduced my caffeine intake by 90%. This was not easy!
My sleep is better, my skin is better, my clarity is better, but my plants are not.
Do plants like caffeine and/or metabolized caffeine by-products?
