Humidity question

I've read a few threads from Zander about the benefits of humidity control during your grow but how do you check what your humidity level is. Is there some kind of meter I'm not aware of that can do this.

You can get a therometer and RH (relative humidity) meter combo. Not that expensive. You should be able to get one for like 20 bucks or so.

See example:
Amazon.com: Timex TX5170 Indoor/Outdoor Thermometer with Indoor Hygrometer and Clock: Home & Garden

If you don't control your humidity within reason or add something to avoid mold, you could get bit in the butt at harvest time.

Humidity is measured by a hygrometer and is very important to know during your grow. The more humid the room is, the less resin the plant produces. Also like someone up there said, high humidity is ideal for mold growth, which could ruin your crop either in flowering or after harvest and flush 4 months of time and effort down the drain. Its very important to know what your humidity level is.

The best option is to get a battery powered meter that will run you about $20-30. Mine tells the temp and also has a high/low function where I get the highs and lows of temperature and humidity until I reset it and it also has a wire that I can place anywhere and it will tell me the temp there as well (i.e. the top of the canopy). If you are realy strapped for cash, you can get a small one for reptile cages as a pet store for a couple bucks. Its just a regular old gague but they are usably accurate.

Thanks for the feed back, I really don't think I have high humidity if anything I thought it might be too dry but I will definitely pick up a meter today

If your humidity is too dry, watch out for that as well. Spider mites feed on a nice dry area. I'd suggest using neem oil all through veg and stop using it in the last couple of weeks of bloom. It smells funny but it works well.
