Ive seen/read of it happening mate, but only once it had been potted. I was lucky/unlucky to see it happen when germinating. Still not sure as to why it happens. I germed this big bang seed the other day and this is what happened...
. The seed has spat out a shoot complete with cotyledon and is starting to grow out another. V strange. Im guessing its just the plant version of twins ? But ive read one will likely be more dominant than the other.
