Things to consider when buying a humidifier

Commercial-Cannabis-Dehumidifiers

Buying a humidifier for your marijuana may not be as simple as you may think. You need to consider several factors before spending your money on the wrong appliance, below are some of the things to take into consideration

Room size

This is the first consideration to make because if you have a small grow room, you will not need to go for large appliances that hold many gallons of water. Luckily, there are humidifiers for all types and sizes of rooms. Buy one that is appropriate for the size to in order to get maximum results from your plants.

Type of Humidifier

Humidifiers come in different types. First carry out an extensive review of the different types there are in the market and choose your preference. The most common types of humidifiers are the cool mist and the warm mist models. Both have the same functions, but their features and prices differ so your choice will largely depend on your preference.

Run time also differs from one humidifier to the next. Buy a humidifier that clearly states what its run time is. While some go for 24 hours or even as little as 12 hours, others go for even up to 70 hours. You will not find a humidifier that runs indefinitely so make a decision on what you want your appliances run time to be in order to achieve maximum results

Control Timer

Getting a humidifier with a timer will safeguard your crops from over humidification. A timer will allow you to control the humidifier for the period suitable for your crops. A timer will stop at the time you want it to if you get an appliance without a timer and you get help up somewhere or forget to go and switch off the timer; you could put your crops at risk.

Easy to use

Buy a humidifier that is easy to use even for first time users and growers. Do not go for a product that will give you a headache to use. You are farming, not trying to fly to the moon so ensure that the design and all the features are easy to use. When we say user friendly, we mean the appliance should be easy to clean, easy to assemble, easy to move around, have buttons that are easy to operate and a LED screen that clearly indicates the humidity levels. The speed of the fans should also be easy to control.

Cleaning and Maintenance

Getting a humidifier that is hard to clean and maintain is frustrating. A clean unit also ensures that the moisture going out of the unit is both safe and clean. Not cleaning well will harm your crops because the mist emission and moisture in the room will be unclean. A dirty appliance may also cost you more for maintenance because chances are it will break down more often than not.

Affordability

Many new farmers will probably opt for the cheap products because they are just starting out. Others may feel that the cheaper the product, the less effective the results. It is not always true that neither expensive is always the best nor is it true that with cheap, you can save. You may be buying a cheap product to try to save some money but the product ends up costing more for maintenance. You may also go for a very expensive product only to realize that it does not deliver as expected. Remember that every humidifier has its own maintenance ad operating costs. Get one that will not cost you much to maintain.

Auto shut off Humidistat

The auto shut off unit that automatically stops when the water tank is empty or when the humidifier reaches, its desired moisture level is called a humidistat. If you do not want to over humidify your grow room, then get a product with an auto shut off humidistat.

Why use a dehumidifier?

Now the question you may want to ask why is there need to remove moisture from a grow tent. A dehumidifier is just as important as humidifier. Excess moisture can damage your marijuana plants and you need the above appliance to take care of that to protect your plants from mold and mildew. Too much humidity levels could also lead to the plants getting a disease. To get the best from a weed humidifier, there are several things to consider. These are

Effective ventilation

A grow room needs effective ventilation to make sure that the humidity is not excessive compared to your weed requirements. If the ventilation is too much, there will a lot of moisture in the room. To balance this, you need a dehumidifier to suck in the excess moisture.

Where you place the appliance

The placement of the humidifier or dehumidifier will also affect the growth and wellbeing of your crops. Choose the right location where the humidifier can ensure maximum ability to draw out moisture from the grow room. If you are using a single dehumidifier, place it in a central place in the room or above a LED grow light. Do not place the appliance very close to the marijuana plants. Also, make sure you have the correct spacing depending on the size of humidifier.

Wrapping it up

By now, you must be aware and convinced that a humidifier or dehumidifier is essential for the growth of your marijuana plants. You need to put it into consideration when you doing your grow room set up irrespective of the grow room size. Invest in the right humidifier that you are sure is capable of drawing out any excess moisture in the air and keeping the set moisture balance in place.
