 As a Botanist, you should look into increasing the potency of your plants. This is shown by the size of the plant's sprite, and can increase the amount of chemicals, points gained from grinding them in the biogenerator, and lets people know you are a proficient botanist.
 As a Botanist, you can combine production trait chemicals and mix your own complex chemicals inside of the plants themselves using precursors. Chlorine (blumpkin) + radium and phosphorus (glowshrooms) equals unstable mutagen!
 As a Botanist, earthsblood is an incredibly powerful chemical found in Ambrosia Gaia, it heals all types of damages very rapidly but causes lingering brain damage and has a nasty overdose. You can combine the chemicals from watermelons (water), grass (hydrogen), and cherries (sugar) to mix mannitol in with your earthsblood to completely counteract its main drawback!
-As a Botanist, Ambrosia Gaia is a plant mutated from Ambrosia Deus, which is a plant mutated from Ambrosia Vulgaris. The reagent contained within this plant known as earthsblood can make your trays and soil plots completely self sufficient when a plant containing such reagent is composted into them, meaning they won't need nutrients or water, and they'll automatically kill their own weeds and pests.
+As a Botanist, Ambrosia Gaia is a plant mutated from Ambrosia Deus, which is a plant mutated from Ambrosia Vulgaris. The reagent contained within this plant known as earthsblood makes for a vastly superior fertilizer than most, giving decent stat boosts to most stats, and automatically killing weeds and pests!
