Ellie's Ideal Greenhouse Game is a mod of The Harvest Mod which focuses on the idea of a green house that expands upon the concepts of the original game. It includes three main options to choose from, each expanding upon the idea behind the original. You can build the greenhouse on the Farm Island by purchasing or building directly from scratch or you can purchase one of the many expansions which include different new decorations, plants, animals and recipes. The main difference between the two is that with the expansion you can change the map locations, which are random every time you take a turn on the game, making the game much more interesting.

This mod also includes the game's first craftable building, the Sunflower Port. This building allows players to transfer crops and crafts to the Sunflower Island by using crafting supplies and seeds. Craftable items include tables, chairs, shelves, binoculars and other farm buildings which can be crafted. There are four possible colors for the Sunflower Port, namely, red, yellow, orange and blue. This mod also comes with two music songs, The Day The Earth Stood Still and Good Day Blues.

The mod also includes two notes view notes, which allow players to reminisce about happier times on the farm. Two notes describe scenes from two years ago and are placed in specific spots on the map. To view these notes, you must travel to the appropriate location on the map. This mod is currently only available for the PC.
