Speed-Gro is a Fertilizer that helps by speeding crop growth. It can be crafted or purchased from Pierre's for 
100g. Twenty Speed-Gro is the reward for completing the 
Spring Crops Bundle in the Pantry.
Speed-Gro can be placed on tilled soil before or after planting a seed, or at any stage of crop growth. However, as of v1.2, it has no effect unless applied before planting a seed.
Speed-Gro Cost
Crafting Speed-Gro used to be cheaper than purchasing it, but that is no longer the case. The table below compares the cost of crafting Speed-Gro against purchasing it at Pierre's. The cost of crafting is the sell price of the constituent ingredients.
