The original plants fishing game
The seeds you can get randomly during extracts. They are one of the most important part of the game, because they will produce the ingredients for potions.
When extracting in a cluster, you have a chance to get random seeds that are stored in your game account. To check the seeds you already have you need to use your HUD, that has a button to list the seeds.
To get ingredients from a seed you need to plant it in a special Seed Plot. You can get one for free to start in the Store at game's HQ.
Each plant has a requirement in water and plant food, both earned also during extracts, and also has a time to grow. In the Seeds Database page you can see these requirements for each seed.
To plant a seed you need to touch a shovel in the Seed Plot, choose what ingredient you want, and then one of the available seeds. If a seed don't appear is because you don't have enough water or plant food for it.
When the seed is planted, the shovel will turn into a small red plant. While the seed grows, this plant will increase in size and change color to yellow, green, and then white, the color of a fully grown seed.
When the seed is 100% grown, you just need to touch it to collect the ingredients and a plant.
Ingredients are also stored in you game account and you need the HUD to check them. You need ingredients to produce potions with the Ingredients Mixer. Check the page 'How to make potions' for more information.
The plant is also stored in game account, and you can get a list of available plants in the HUD. If you want an object of the plant to decorate your land, you need to get it at the Seed Exchange.
Seeds, Ingredients, and Plants you have can be listed in the HUD. Check the Player Guide for more information on how to use the HUD.
