Low Humidity 35% is this an issue and how can I increase?

I agree with Oganoman here. The only time low humidity is ever an issue in my grows is when talking seedlings/baby clones since they don't have root systems yet. A plant in full veg will just drink/respire more in low humidity situations. The low humidity is actually a blessing during flower when you're looking to drive it down anyway for mold prevention.

This is what you need: https://www.amazon.com/dp/B07H2717BM/ref=cm_sw_r_cp_apap_3GJ7GbQe5csKk Otherwise, a bucket of water with a rag half in and half out and a fan blowing on the rag will increase your humidity 5-10%.

Hi mate, before I bought a humidifier I used to hang thick wet towels up in the space. It brought the RH up by 5%. Adding a bowl of water will bring it up a little too. spend some money on a humidifier and humidity controller.

I've used a pot of water with a fan blowing on it. At lights off I've sprayed the walls of my tent with water. Best way is to control humidity outside of grow area with a wick style humidifier. I do not recommend cool mist humidifier or you will end up with white powder everywhere if you don't use deionized or distilled water.

Hi bro, you can buy ultrasonic humidifier, you can also find cheap ones online, home remedies like water bowls, sponges etc. they are not effective at all. anyway believe me friend, much better this way than having to get rid of the humidity. a greeting good luck !
