GMSgrowsanswered grow question 3 years ago I've never had store bought seeds herm on me. It all depends on if you know what your doing or not. If you constantly high stress the plant it could turn, but otherwise if you have a great environment and no stress factors and the plant harmed., I would never buy from that company again. In my opinion Bernie plants always create more hermie plants. When you use bag seeds, you always run the risk of a plant going transgender lmao...
