Tutorial: how to get adventure mode plants earlier than you unlock IT?

To unlock an adventure mode plant , you actually don't need to Play the Level, where you unlock IT. First Thing is, that you get already get the seeds for the plant from pinjatàs. Second is that you can get seeds of the plant by watching add or for paying with coins or gems (you Open the menu for These Things by taping in the almanac on a adventure mode plant  and clicking  on "get more seeds").

Third is, that in the Shop, when you click on "adventure", you can get plant seeds almost the Same way as in the second Option , but there are more seeds for gems. The first and the second Option I used to get SHADOW SHROOM and GRIMMROSE earlier than I was  supposed to get them.
