I have floating bulb plant that refuses to stay put. I can not find any flexible plant weights but i have a tackle box with lead weights can i use those safely?
Plant weights are thin strips of lead so I see no harm. Most of today's fishing weights are now made of nickel, steel and other metals other than lead.
You can also use non-leaded solder (solid core) to wrap around stems.
Actually those plant weights are made of misc. metals too, if they were still lead, they would have warnings all over them, especially if they are for sale in California.
