I know nothing about tropical, other than what i have heard. They are great, that's all. But for my experience, ACE Golden Tiger have been the most vigorous and healthy plants i have come to encounter in my 6 months growing... LOL
I germinate a lot of seeds and keep only the most excellent ones, but my experience limits my judgement, most of the time. Anyway, I have germed a lot of seeds in the last few months, and ACE really impressed me.
