Purpose and how to use it
Gain more Crop Mastery progress from each harvest.
The Greenhouse adds fractional harvest-equivalent progress toward Crop Mastery. It does not directly multiply Harvest Points. At Level 25, one seed harvest supplies 1.2 mastery progress before companion effects.
Click the building on your farm to open its menu. Moving a building changes its location, not its owned level. Farm editor placement rules explain entrances and walking access.
Where to get it
The Greenhouse is included with your farm at Level 1; you do not buy a separate building from the seed shop. Find it on My Farm and click its model to open its menu. If you stored or moved it, open Edit Farm → Buildings, select the owned building and place it again. Its level improvements are purchased from its own menu, not by buying another copy.
Every level: benefits, costs and requirements
Exact rule at building level L: Additional mastery progress fraction = (L − 1) ÷ 120. Percentage displays are rounded to at most four decimal places; the fraction above defines the exact calculation.

How bonuses combine
Building effects apply only to their named mechanic. Active companion effects combine with buildings under the game’s caps: late-penalty reduction 75%, weather-bonus strength increase 100%, fertilizer strength increase 50%, seed grow-time reduction 34%, and automation capacity 96 hours. These caps describe fully combined systems, not bonuses supplied by this building alone.
