I’m compelled to point out that “auxin” is a compound created in a plant’s roots and transported up into the plant, and is the thing that stimulates new growth at the growing tips of the branches/limbs.
Auxin is alto present in fast growing annuals like cannabis, but I would not know anything about that.
Go for a change! Move to the Pacific Northwest and grow Kelp! Lots of auxin and on a good day, 2 to 3 feet of growth. The barbeque is good and all, but there are disadvantages to living some place that keeps all its rivers underground to keep them from evaporating!
Kelp. Good fertilizer for other plants! Or, roll it up with raw fish and rice and sell it in California!
