Is that a marketing name for a product or is it actual lead, a heavy metal that is toxic?
If it is the liquified metal then people using that should be strung up by their balls and flogged with a 'cat 'o nine tails' (barbed wire whip used over 100 years ago on convicts) and that is the nice version of what I think.
I just want a good yield so I don't have to do as many crops and save electricity. Even if I sold, I wouldn't spray them with sugar or anything, that's low.
