Hello from several years out.
Here is a post I made that touches on this subject.
Rudolf Steiner’s protege, Alan Chadwick and his Grow Biointensive method were proponents of a lunar cycle based planting, transplanting and harvesting technique that has, anecdotally for me at least, showed definitive advantages over random methods.
Steiner’s lectures, compiled in a tome named “Agriculture”, sparked the biodynamic movement.
One day I’ll have the time to read the whole thing as from the first page it looks like a saucy scandalous good time.
And that’s not even touching the “Preps”!
“But, lo and behold, Frau Prof. Schleiden rebelled. She preferred the indications of Prof. Fechner to those of her own husband. And so indeed it is. Science may be perfectly correct. Real life, however, often cannot afford to take its cue from the “correctness” of science!”
Edit
Found a pdf.
