Best Humidifier for Grow Room Setup

Posted by David Allen on Feb 6, 2019

buying-a-humidifier-for-your-grow-roomWhether starting from seedlings or clones, the biggest thing affecting a young cannabis plant’s growth is the room’s climate. In the first couple weeks, plants need steady temperatures between 70 and 80-degrees Fahrenheit with Relative Humidity (RH) around 65-70%. For most, getting humidity and temperature lower is the daily challenge, but with young plants they need the higher numbers to promote vigorous growth. When the plants are freshly propagated they don’t have roots yet to bring in enough water to support themselves so they rely on the air’s RH to both provide water and create external pressure that acts as a sort of seal for locking moisture in the leaves. Once the roots begin to develop, humidity is gradually lowered telling the plant to search for water with additional root growth.

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 a 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 and Natural options.

Determining the Size of Your Space

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


What Features Do You Need?

Automation is almost always better, but of course it also costs more money up front. At 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, 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.
