Stimulates leaf production. Guaranteed to increase growth rate by at least 10%. Mix into tilled soil.

Overview

Speed-Gro is a fertilizer that increases crop growth speed by 10%, or by 20% with the Agriculturist profession. It can be crafted, obtained from a Bone Mill, or purchased from Stone’s starting on Spring 15 of Year 1. Twenty Speed-Gro is also awarded for completing a bundle.

It can be applied to tilled soil before or after planting a seed, and it may also be added at any later stage of crop growth. Like other fertilizers, it does not reduce the time between harvests for multi-harvest crops. Although it can be used after planting, the benefit is not applied retroactively to growth stages that have already passed, so the practical reduction in total grow time is often less than the listed percentage.

A few details make Speed-Gro more specialized than its description suggests:

  • It reduces a fixed number of days from each growth stage rather than lowering the total grow time evenly.
  • Because earlier stages are affected more heavily, the overall time saved is smaller than the advertised 10% in many cases.
  • It can still be useful on crops with long early stages, especially when trying to reach a harvest faster in a new season.
  • It has no effect on regrowth timing for crops that produce repeatedly after harvest.

Speed-Gro also has non-farming uses. It can be placed in the sewing machine spool to create the dyeable High-Waisted Shirt, and it can be used as an orange dye in dye pots. This gives the item a small role beyond agriculture, even though its main purpose remains speeding up crop production.

As a crafting ingredient, Speed-Gro is available relatively early thanks to its Farming Level 3 recipe, making it one of the first growth-boosting fertilizers many players can produce consistently. Its availability from multiple sources means it can be used either as a convenient early-game boost or as a supplement when specific crops need to mature on schedule.
