This article has a money making guide here: Humidifying clay.
Please add tips to the subpage, rather than the article below.

The humidify spell will fill all empty water-carrying vessels in a player's inventory with a single casting including bucketsfishbowlsjugsvialswatering cans, tree seed saplings, waterskinsbowls and clay. A player receives 65 experience per cast, regardless of the number of vessels they have filled. Fishbowls and watering cans are not tradeable if they contain water. It can also be used to extinguish the wall of flames during the fight with the great olm in the Chambers of Xeric.

Players travelling in the desert may find this spell useful so they can refill their waterskins without cutting cacti. Players on Lunar spells also find Humidify useful when farming multiple allotments, and may use Cure Plant and Fertile Soil as well.

Casting humidify can also be used to train Magic while making a fair profit. This can be done by buying empty vials from an NPC store such as the Shilo Village General Store or the Lunar Isle General Store and converting them into vials of water. Humidify can also used to help save time when making soft clay by having the dry clay in one's inventory, and casting the spell. This turns all clay into soft clay. A steam battlestaff, or a staff of water in conjunction with a tome of fire can be used for maximum efficiency.

To maximise training with this spell it's best to use a fishbowl and set it underneath the spell spot (as if you were high alchemising) and to use the "F1" and "F6" keys (or whatever F-keys you have set to the spellbook and inventory) to switch back and forth between spell and inventory. This makes it extremely easy to cast the spell repeatedly, since the fishbowl's left-click option is Empty. This spell is the same speed as casting Low Level Alchemy, yet it provides the same experience per cast as High Level Alchemy. Note that casting High Level Alchemy is presumably always cheaper, as training via High Alchemy has typically low or no cost, as a multitude of specific items can be alchemized for significant profits, whereas casting humidify on a fishbowl and emptying it again will always result in a loss. When you first hear the sound effect, it means that all vessels have been filled. If timed correctly you can bank or train with the fishbowl with ease.
