Pump Room effects (all spoilers)

[Stone]

Pump Room - What does the different filled meters do?

Not complete info, genuine questions here. Updating if I can!


Fountain - Allows underground access (requires a key)
Reservoir - Lowered = Allows boat, Fully lowered = Sanctum key in one of many many trunks on bottom
Aquarium - Let's you see diffuse hints? X and Arrow etc. (haven't used these) Anything else?
Kitchen - No idea. (?)
Greenhouse - It waters the plants, creating gems, likely dependent on soil quality.
Pool - You can loot the gold in the bottom, a future upgrade gives you "swim trunks" :)

Greenhouse is 2-3 gem flowers with full water

Greenhouse gems are based on soil quality, I think

Kind of a minor one, but when the Kitchen is being supplied with water, you can refill the watering can at the kitchen sink.
