It all sounds quite simple on paper but even the most experienced grower will struggle without the right tools in their grow room or propagation tent. For consistent success, you’ll want to have a humidifier (or two - remember to always have redundancy built into your setup in case any equipment fails) on hand to get your cuttings off and running without missing a beat. Investing in a humidifier for your young plants will more than pay for itself over time with increased plant size, yields, and faster root development.
We’ve already put together a guide explaining the different types of humidifiers on the market which should help you decide what will be best for your setup. Feel free to take a moment to refresh your memory on humidifier-type pros and cons then let’s take a look at some great, Pure n Natural options.
A little simple math of “Length x Width x Height” will give us the room’s square footage which we’ll need to know for selecting the right humidifier size. It may seem like bigger is better, but consider this: You wouldn’t bring a jackhammer to open a jar of mustard in the same way you wouldn’t bring a teaspoon to quarry rocks. The right tool for the job will always yield better results.
| Small humidifiers | 300 square feet |
| Medium humidifiers | 350-500 square feet |
| Large humidifiers | 550-1000+ square feet |
Automation is almost always better, but of course, it also costs more money upfront. At a minimum, every humidifier you consider should have a built-in hygrometer to measure the room’s RH and keep it consistent at your desired levels or be able to link to an external hygrometer that controls your humidifier’s output. Noise levels, filtration types, and warm mist versus cool mist will all be specific to the needs of your individual growing space and preferences. It may seem complicated but we’ll try to make this as easy as possible with some featured humidifiers in each size range with some basic specs and notable features. Let’s begin.

Then, the cool mist is blown into the room where it evaporates immediately. The super quiet humidifier consumes very little power, and a replaceable demineralization cartridge ensures water mist without limescale or mineral residues.
