So I got the greenhouse unlocked and I wanted to plant something in it. But when I first tried to water the ground nothing happened. So I placed a sprinkler and that didn't work too. I tried to plant something without water and that also didn't work. So I restarted the game and it still didn't work. I have looked online for a salutation but I found nothing. I hope someone can help me with this problem. I play on PC and I do not use any mods.
