| Sell Price | 70g |
Hyper Speed-Gro is the strongest growth fertiliser a farm can use. It cuts a crop's growing time by a third, and the Agriculturist profession raises that to well over two fifths. No shop sells the bags, so every one has to be crafted. The recipe sits in Mr. Qi's shop on Ginger Island, which marks it as late-game gear. Its ingredients come from dangerous floors and monster drops, so a stack of it reflects real time spent in combat.
Recipe
The recipe is bought with Qi Gems in Qi's Walnut Room. That room is on the west side of Ginger Island, behind a door that opens once a hundred Golden Walnuts have been found. Qi Gems come from Qi's own Special Orders board in the same room, from the Shrine of Challenge, and from trading in spare Golden Walnuts.
Each bag needs one Radioactive Ore, three Bone Fragments and one Solar Essence. The ore is the hard part. Radioactive Nodes only show up in the Mines or the Skull Cavern once their danger mode is switched on. Qi's harder special orders do that for a week, and the Shrine of Challenge or the statue at the Skull Cavern entrance turns it on by choice. Good daily luck makes the nodes far more common.
Solar Essence drops from Ghosts, Metal Heads, Mummies and Squid Kids. Krobus also sells it in the Sewers every day. Bone Fragments drop from Skeletons and turn up at the Ginger Island Dig Site.
These are the ingredients one batch needs.

Use
Like the other growth fertilisers, it goes into tilled soil and can be added before planting or while the crop is already growing. Only one fertiliser fits on each tile.
The full third is only reached when the bag goes down with the seed. The reduction is applied to each growth stage, and the first stages carry most of the saving. Adding it halfway through skips those early stages, so the crop finishes only a little sooner.
The boost covers the first growing period only. Crops that keep producing after the first picking, such as Coffee or Hops, return on their usual timer.

Notes
The Greenhouse is a good home for it. Soil there is never reset by the seasons, so the bag stays in the tile until a Pickaxe breaks up the ground. One application keeps speeding up crop after crop on that spot.
Outdoors, the fertiliser normally vanishes from the soil when the season changes. Each new season on the open farm needs fresh bags.
