What brand gel caps do you use?
I am going to make some root tabs full of osmocote plus. It seems like 00 is a pretty common size, but do y'all use any particular brand? I see some sellers listing kosher etc. do the gel caps need to be kosher to ensure there aren't any random things that could leech into the aquarium? I am not planning on selling them, I will be using the osmocote for my urban garden too. Please help!
