The review came to the following conclusions in 2020 :
5. Conclusions
Science has widely established different evidences: (i) the Moon’s gravity on the Earth cannot have
any eect on the life cycle of plants due to the fact that it is almost 300,000 times lower
that the Earth’s gravity; (ii) since all the oceans are communicated and we can consider their size being
the size of the Earth, the Moon’s influence on the tides is 106 ms2, but for a 2 m height plant such
value is 3 1013 ms2 and, therefore, completely imperceptible; (iii) the Moon’s illuminance cannot
have any effect on plant life since it is, at best, 128,000 times lower than the minimum of sunlight on an
average day; (iv) the rest of possible effects of the Moon on the Earth (e.g., magnetic field, polarization
of light) are non-existent.
The logical consequence of such evidence is that none of these eects appear in physics and
biology reference handbooks. However, many of these beliefs are deeply ingrained in both agricultural
traditions and collective imagery. This shows that more research should be undertaken on the possible effects observed on plants and assigned to the Moon by the popular belief, addressing their causes,
if any. It would also be interesting to address these issues in both compulsory education and formal
higher agricultural education in order to address pseudo-scientific ideas and promote critical thinking.

Yes science doesn't have all the answers and has no wisdom as it is based on testing hypotheses.It is always better to know what thoughts there are and what is published on views you don't share as it allows you to believe wih more vigour when can consider things from all sides.
