Humidity too low?

My humidity wont go above 25%. My two plants are veggin and acouple leave edges are curling up toward the light. Is this because humidity too low. I have a 400watt cool tube in a 4x4x6.5 grow tent. Whats a cheap way to increase humidity?

humidifer's are pretty cheap you can get one for around $20. or you could just hang a wet towel in the room, basically any thing that water can evaperate off into the air from. happy smokin!

Dude you should try grouping the plants togeather,the water vapor they give off will help other the other plants, like put em as close to eachother as u can.

the wet towel thing is a gud idea too!

or get a bucket of water and leave it to evoporate try the "paper towels in a bowl of water" method. and put it under a heating pad if u can.will work better i beleive!

also , mist your plants man.



Cheers
