Humidity Problems

Hey everyone i hope someone might be able to give me a little help in increasing my humidity. It sits at 30 - 35% humidity at about 79 degrees farenheight. I am using a 600 HPS on one 4 week old lavender x widow. I am using the deep water culture method and it is working out great.

I placed bowls of water around the plant for evaporation, and i have been misting under the fan leaves with RO water. I have noticed the edges of all the fan leaves curl up towards the light. (Humidity problem?) Everything else looks great. Thanks

Me too, very simlar grow and stage.
35 isn't that bad though, I think a lot of grower like it there.

Now I offer this addvice with extream cortion, care must be taken over wise you risk mould.

When I have really low humidity I hang a Wet Towel in the room. It raises humitity 10% average.
BUT; try not to let it hang on the walls, use a clean towel every day, and put a try down to catch the drips. If you are carefull its a really cheap way to up the humidity.
