how to sell seeds

In Plant Tycoon, only the plants can be sold. The seeds that you get from polliating your plants (or that you buy from the shop) are stored in the seed tray for you to grow new plants from.

i though when polliating is come randomly...
cannot choose which go with which isn't it??????????

Breeding results are always predictable, and you have complete control over which plants to pollinate with each other.
