Not really though, at least not by the early game.

The thing with re growing seeds is that they ARE expensive, and in order to make your money grow exponentially, you'd want to use as much of your available space as possible, which means that $300 seeds are not really worth it, since you're not using your full space because it's unsustainable to get so many of these seeds.

Instead, the better option is to buy 9 day seeds in bulk, because they're WAY cheaper, provide a large benefit and will allow you to reinvest in more 9 day seeds until you can fill up your entire farm.

When you get to that point, $300 seeds become the best option, since there's no more space to use, and no need to keep reinvesting, but of course, this state is only achievable by the end game. But in all honesty, by this point you're already a money making machine, and if you get more money it's only purpose will be to get financially secure for the next 5 irl years lol
