The Green House is one of the most useful facilities you can get in Coral Island.

It gives you a 14×14 farm area that can grow any crops, no matter what season you are in currently. This is the only way to harvest plants out of season!

Read on and we’ll go tell you everything you need to get your own Green House built.

How to Build the Green House in Coral Island

To get the Green House, you need to complete the first altar at the Lake Temple.

This consists of bringing a variety of offerings that fit into 6 different categories. Four of the categories represent different seasons, so you will have to make sure to get the offerings each season.

The first category is Essential Resources. These are basic materials that can be obtained at any time, such as Wood and Stone.

Next, we have the Seasonal Sesajens. To complete these, you will need to get resources, plants, vegetables, and fruits that only appear during the respective seasons.

For example, we first have the Spring Sesajen. As you might imagine, this covers offerings of items that can only be gathered and grown during Spring. The same logic applies to all 4 seasonal offerings.

Lastly, we have the Ocean Loot offerings. You will need to look for these resources as you dive into the ocean. Take particular care of looking for Sea Salt, which looks like simple white rocks!

To complicate things a bit more, some of the offerings can only be grown and harvested once you level up your town rank.

Nonetheless, you just need to gather all of the offerings for each category. Each completed category will give you a different reward, and completing all of them will unlock the Green House.

After you give all the offerings to all categories, just wait one in-game day. The Green House will be built overnight! That’s all there is to it.
