I'm new to this forum so Hi - I would like information on procedure to Level 21 re colours needed etc.
Also blonde ?of the day how does one locate the Shoppe other than via clicking on an empty pot.
Sunshine smiles to all

Hi catoosh, welcome to the forum!

To get to Level 21 you just need to harvest 2 different Piscis Aquabullae.
Then, to reach Level 22 you need to harvest 2 more different Piscis Aquabullae; different colours to before.
It's all here in this thread: What do I need to grow?

Do you mean 'how do you get to the seed shoppe'?
Well, if you go to the flower pot shoppe (Buy a new Flower Pot under Options), and then change the word 'pot' to 'seed' in the link in your browser, you can view the seed shoppe whenever you wish! I hope that is what you were after.

many thanks for the prompt reply
