Here’s the hard part ->[Guide] Goo color mixing guide
Your setup is divided into two parts. One is the mutation farm, the other the crop farm.
What is best depends on personal preference, here’s my setup:
For the mutation farm I use only growth and raw gleam, gives a 0% on crop and a 90% on seed. For the gleam you use it’ s up to you to figure out a good setup not gonna spoil which colors to grow lol ; P
For the crop setup it’s all lava and rocks (rock color has no influence on the random mutations occuring during crop raising). Gives a setup of 220% crop and 80% seed. This is preferably to using sponge imo since you replant a lot of kernels multiple times, yielding a lot of pigments.
The mutation is labor intense, you will replant all kernels once matured to the same gleam block until they reach your goal color (gleam color or a color you want). Once Mutated you transfer them to the crop farm.
Any questions? ^ _ ^ /
