Has anyone used magnets to benefit plants? Or treated seed?
The suns light is electromagnetic.
I have. The south pole will cause above ground crop seeds to sprout earlier. While the
north pole will take longer to sprout and the plants will be long and spinlly.
Below ground plants like beets the north pole works best.
You have to have a 2,000 to 3,000 gaus magnet. And
the magnets have to be properly marked with the correct pole North or South.
The late Dr. Roy Davis did extensive research on the subject.
You can google him on the web. Or google Bio magnets. Or Magnetism affect on plants.
You will find pros and cons but if you don't have a 2,000 to 3,000 gaus magnet it will not show results.

Interesting!

Have you ever noticed that there is always a similar relationship between the health and growth of plants and humans?

I broke my left humus in an bicycle accident last year, and I had to wear a powerful electomagnet on my arm for 1-10 hours per day for several months for healing the bone.

Magnetism must work in building human bone cells just like plant cells.

Happy Gardening!
