Stardew Valley: How To Unlock The Greenhouse
Located a short distance from your house in Stardew Valley is a dilapidated building. The building is the Greenhouse, which can be repaired and used after completing the corresponding section of the Community Center or by paying the fee at Joja Mart. Repairing the Greenhouse allows you to grow crops inside, ignoring the seasonal restriction on crops that are planted outside.
How to unlock the Greenhouse
There are two ways to unlock the Greenhouse, depending on which story path you are going down. If you are doing Joja Mart, you simply need to pay the 35,000G fee to have it repaired. After paying the fee, the Greenhouse will be repaired overnight.
If you are doing the Community Center path, the more popular of the two paths, you will need to fully complete the Pantry bundles. The Pantry is unlocked after completing one bundle. There are six individual bundles in the pantry, all of which are themed around crops and other farming goods, like animal products and artisan items.
