If you can do another one without the copper pipe , just the spiral wire.

Thanks. Should I use bamboo or wood instead for support? Or just pull out the pipe?
If possible keep the one with the pipe just get another one. Wood or bamboo should be fine.
But the experiment was really to prove it works so I wanted to keep one without any wire at all as the control. I'll do another with bamboo in the garden! Thanks!
Absolutely, keep the control. It would be interesting later to see if it’s planted in the ground if it would potentially affect the ability of the electricity to ground itself, whereas in a pot it could change its effectiveness
