Do I still need a humidifier/dehumidifier?

After my new light next on the list was a exhaust fan that can connect to this carbon filter I bought a long time ago. My question is with this humidity controller do I still need to buy a humidifier and dehumidifier

The controller turns fan on/off based on temperature AND/OR humidity. That will help control humidity somewhat but doesn’t necessarily mean you do not need to add on.
So things that will be of concern:
Size of grow area, how many plants, hydro or water/soil, temperature after light is installed, lights on/off schedule.
Opinion - almost everyone needs to ADD humidity to their TENT. Some of us use small cheap reptile devices, some only use water pails / towels, planters with no plants, just wet soil

I don’t know how to answer your question, but I’m enjoying the window shop. :slight_smile: :grin:

@IraSpaunsble yes you would still need a humidifier and dehumidifier. The humidity controller just tells the humidifier, dehumidifier, and fans when to turn off and on based on the parameters you set in the program.
