How can i raise my humidity?

i am doing a grow in my closet. i have a few seedlings coming up and a clone thats about 10' tall. My clone looks as if its burnt. Could this be because my humidity is so low? will this cause a problem with ALL my plants? Seedlings and my clone? Like i said my clone looks light burnt. someone plz tell me how i can raise my humidity levels? my temp is 81. Humidity is at 22.

easy get warm water in a bowl pot whatever can hold 1 gallon of water then stick towel in it slowely till it soaks it all up. place that next to your plant. you can do 2 smaller bowls with wash clothes also jsut use warm to hot water and have a fan blow over it till it reaches the right amount you might have to do this a few times when the bowl cools down. and to keep it up just use small bowl 2 times a day again.
Peace and Love

then when in town next go to a 2nd hand store and see if they have a used humidifier for like $5

your lights and the dry air is killing your plant so yes this will help allot try to get humidity up to 60%

do i place that towel nest to the plant on top of soil or just near the pot? got my temps down to 77-80. looks like just humidity now

will misting my plant work until i get humidifier?

next to the plants in same area anyway. you want the fan to blow across it.

just do the towel/hot water thing is my suggestion.
