Mycelarium Water Guide

Mycelarium (the 2026 incremental game by PLAN KAPKAN) spends water on growth, not on buildings. This page is about that cost. It is not about the cosmetic called micellar water.

Pools, rain, and the Water mushroom

The store says to connect to water reservoirs. A community water guide treats each blue pool as a finite tank: you drink it down, and it is not described as refilling on its own. I leave the refill question open because only that guide states it. During rain, the play video reads an on-screen line that hyphae shots cost no water. That is the window for the long connections you postponed.

Water mushrooms produce water. Their two branches on the official tree are Water Yield and Drop Rate. The achievement Thirsty Shroom asks you to produce 1,000 water with Water mushrooms, so the building is not optional flavour. Players place them beside a node that is already growing, including on tree trunks. Water Efficiency, a base upgrade, is the one that lowers water per centimetre. Buy it before you buy a second water branch you have not placed yet.

Deep water, still thinly sourced

The Steam player guide describes an infinite water source at the bottom of the third layer, red dirt. This remains a single-author report; the status on the fact row stays “1 source”. The grey-dirt screenshot already shows a large pool and a shot preview of 162 cm for 17 water, which is enough to see that distance has a price before you ever reach red dirt.

The magic Water shroom is a different object. It is blue, it sits near the first pools in brown dirt, and its reported effect is a random root from an existing node. That row lives on the magic shroom table. Do not confuse it with the buildable Water mushroom that the achievement counts.

Questions people ask

Why did growth stop?

The pool you were drinking is empty, or rain ended and shots became expensive again. Check the shot preview before you hold the aim.

Does Water Efficiency make water?

No. It lowers the cost of shots. Water mushrooms are what the 1,000-water achievement counts.
