Humidity control without humidifier

I hung wet ( squeezed out and don't let excess drip on seedlings) towels from the rack above the plants. Works well.

You can life hack it if you want but the best and optimal way is to by a humidifier and a ink bird humidity monitor along with a ink bird heat sensor which will keep your VPD in check, i tried to life hack it and after I got the proper hardware I grew some of the best indoor smoke ever, VPD is a key factor to water and nutrient uptake and for your plants to transpire, which is what keeps the nutrient and water uptake going, you want your plants to transpire as much as possible inorder to have them feeding consistently and as much as possible. Your plants will thank you in the end and you won't be disappointed

I use wet towel and hang it from my poles. It'll hold a high RH. Does for me. Good luck

There is methods. But if you want stable humidty which is what plants prefer then bite the bullet and get a humidifier. AC infinity have the best humidifiers on the market .

A container with water and a wide mouth can slightly raise the humidity, for example, put a bucket of water in a tent

Wet shirt or glasses of water

you can minimize the exhaust air, especially from germination to the end of the 1 week there is not much material to photosynthesize. With me the ventilation runs initially only 5min per hour. You can also spray water with a spray in the tent.

Sit a bucket of water Bucket of water in there, use to put a tin can on woodstove in winter, but really evaporation works

Hi! Personally, I hang wet dish-towels in the tent (close to a fan or intake so that moisture is pushed into the air). I spray the towel when the Humidity dips too low. Otherwise, setting some bowls of water near intakes will also increase RH. Good luck!

Hola! Puedes poner una tela colgando en el tent, con la parte de abajo sumergido en un recipiente con agua, de esta manera la tela que absorberá el agua genera vapor dentro del tent por acción de la ventilación y la luminaria 🤞💦♻️
