I am worried about metal posts (support structures for plants) placed in garden and danger from lighting strikes. Posts are 3 meter long rebars and they are about 1,5 m driven into ground. Around garden there are a lot of high trees (some are around 8-10 meters high) and there is two story house nearby.
My question is about possible danger to people working in garden - how dangerous is to be around those posts in case of bad weather (of course, in case of lighting storms no one will be working in garden :)). Will these posts attract lightings more than surrounding trees or house? Will rebars act as lightning rods considering they are half length driven into ground?
Is there a way to improve safety in such scenario because I was thinking about making even higher metal posts to support protective net against hail?
