Can mobiles be place near seedlings during their life cycle , will their rays be bad for heslth of seedlings and plants?
You mean cell phones?
Yes cell phones
Dont think it would do anything unless you dropped it on the seedling.
Its just radio waves and those are present everywhere all day long.
The EMF from the lights is probably stronger than the cell phones
Probably not best - long term, same as holding it to one’s ear next to one’s brain for extended periods of time.
Same principle as: Dont feed Cows, hamburger - MadCow Disease
or dont feed the Chickens, scrambled eggs - Funky Chicken
Cell phones fine, I wouldnt give it the covid vaccine tho
