Can't raise marijuana humidity

A question from a fellow grower:

I have a system titan temp humidty controller but my issue is I bought 2 humidfiers I just spent a 100.00 on a Vornado Evap3 Whole Room Evaporative Humidifier doesn’t work at all…i bought a Honeywell warm mist and a cheap vicks I cant ge the humididty up…i leave the fans off all three intake exshaust and circular and it doesn’t help…i dodnt want to spend over 100.00 150.00 my room is 3x7x8 any adavice will help in the summer not much issue but winter my humidity like 20 to 30 percent …right now its 55 5 weeks into veg I know they do alittle better around 70 …I have to dehumidifers they do the job…i was thinking fogger but not sure if that’s the answer

I need some answers please to humidity

Hanging up wet towels and containers with a large surface area filled with water can raise humidity it’s cheap too

I was hoping not have to fill my grow room with wet towels and constantly wetting them ,but I will try a couple see how it goes …ty Brenda
