Growtopia Splice Planner

Pick any seed and see the whole tree it grows from: what to farm, what to splice, and how many of each for a mass run.

Save, load and projects

Your farm list, pictures, box positions, spliced ticks and projects save automatically in this browser. To back them up or move them to another device, export a save file and import it there.

Prices and live lookup

Enter a price on any seed in the “Seeds to farm” cards to get a cost. GrowPricer and the GTMart Vend Locator load their prices with their own scripts and do not offer a public feed, so prices are typed in or pasted here. Open a site, look the item up, and copy the price across.

How splicing works and where the data comes from

You need an empty space above a solid block, since that is where splicing happens.
Plant one seed, then plant a different seed on the same tile.
If the pair is valid you get the tree of a new item. Harvest it to get seeds of that item.
A recipe only has to be spliced once to unlock it. After that you farm the item like any other seed.

Bracket draws the tree from base seeds (left) to your target (right). Hover a box to trace its path, click a box to open that item.
Build list lists every seed by tier. Tick recipes as you splice them, and press “Farm it” on any seed you want to farm directly. Its whole subtree then drops out of the totals.
Numbers assume the worst case: every branch is grown fresh for each seed you want. Reusing harvested seeds always needs fewer.
