Humidity... with straight answers

I've been trying to look around and read and cant get matching data..

1. What are the low to high levels of humidity during both cycles of vegging/ flower ?

2. What are some easy ways to both raise and drop the humidity?

Now there are only 4 clones in a double sided closet. Cfls so temp is not a problem.
Oscilating fan inside 24/7 and doors are opened to ventilate a few hours a day..

Some help would be grateful and appreciated.. SidNastyVicious

1)35-55% for veg, 35-45% for flower

2)Raise - Humidifier, hang wet towels in the grow room, buckets of water in grow room
Lower- Dehumidifier

60% to 70% in veg, and 30% to 40% in flowering , 75-90% for clones
You should never go above 65%

err.. Out of 2 answers i got 2 different answers for 1 question..
You're not going to get a concrete answer.

I will tell you my experience so far, it's not as important as it's made out to be. Other factors are more important to overall plant health. Ultimately humidity isn't a make or break for the plant.

My first grow the humidity never went above 25% in my grow room and the plants did fine. Was the plant grown optimally? Obviously not. I still harvested three good plants that gave me an avg. of 1oz per plant though.

Second time around now and I've managed to keep my humidity around 40% and the plants are doing well. not really any different than the first grow though.

IMO I would say 30%-50% RH. Higher humidity in flowering is obviously going to make it easier for mold growth, so try to stay at the lower end of the spectrum.
