not sure which to get I asked the guy and told him I wanted bubble gummer which is 4 seeds, he recommended me the big bang 2, which I assume is the version 2 of big bang. Anyway big bang 2 was twice the price but he said he would do it for same price if I upgraded from bubble gummer to big bang 2, so I'm getting an extra seed and a different/more expensive one for same price. Now I understand these are marketing strategies sometimes the product isn't as good and they're trying to get rid of it, or maybe have high amount of stock? so help not sure
