What is Cultivation?

Blazenut is a Material and a Pouch Item in Monster Hunter World (MHW). These useful parts are collected by Hunters to craft new Items, and can be brought along on hunts in the Item Pouch. Used to make Gunpowder that greatly increases Ammo firepower. In Iceborne, you can unlock a fourth cultivating slot as well as upgrade your existing box to hold more farmed items. To unlock this upgrade, you’ll need to complete three quest steps.

Cultivation is the act of growing plants, bugs, and other essential materials used to craft consumables. Most of these materials can be gathered during expeditions, though it can be tedious and time-consuming. Being able to grow them at the research base is much more convenient.

Cultivating materials costs research points and is one of the best investments for the currency. It allows you to stockpile a hefty amount of items to make healing items, traps, slinger ammo, and other useful consumables you should bring on quests.

Cultivation is unlocked by visiting the botanical research center in Astera. At first, you will only be able to cultivate one type of material. You can upgrade the research center’s features by completing various deliveries and optional quests.

Recommended Materials to Cultivate

Honey

Honey is used in making potent healing items like mega potions, first-aid meds+, and max potions. Because of this, you are likely to burn through your supply very quickly. This is especially true if you always carry some honey with you to craft more restorative items in the heat of battle. Try to maintain a good stockpile of honey at all times.

Mandragora

Mandragora is the key ingredient used in crafting max potions. There are very few places to gather it during expeditions, so being able to grow them by yourself is extremely advantageous.

Flashbugs

Flashbugs are used to make flashpods, a type of slinger ammo that momentarily stuns monsters when fired. It also forces airborne foes to crash down, briefly giving you time to attack them without restraint. Flashpods are very effective against Rathalos, Rathian, Legiana, and even the elder dragons. It is easy to burn through a stash of flashpods, especially when running optional quests and investigations multiple times. Be sure to keep a hefty supply of them through cultivation.

Might Seeds

If you think you have stockpiled enough materials to make consumables, you can try to earn some money by growing might seeds. These sell for 140 z each for a good profit. You can also use them during quests to temporarily increase your attack power.

Other Materials

Bitterbugs, blue mushrooms, herbs, and sleep herbs are some of the materials that you will also likely deplete very quickly if you do not take time to gather them during expeditions. Cultivate as much as you need, since you will accumulate a good amount of research points just by going through the main story.
