temperature vs humidity

[shiloh]

what is the different between temperature and humidity in the room...well, i guess i know the temperature in the room and how to adjusted..but what is the humidity..how do you determine the humidity of the room and how do u adjust it..one last ques. what is RO water? thanks

Well, humidity is the amount of moisture in the air measured from 0% (no moisture) to 100% (raining or fog in the middle of the summer in temperate regions)

If a room needs a certain humidity, get an inexpensive humidifier at a store like a drug store (one that you'd put by your bedside if you've got a bad cold), a fan and a hygrometer. A hygrometer can be obtained at a pet store and is used to take readings of temperature and humidity for reptile cages. Get a digital one. Dial ones are hard to read and are less accurate.

The fan helps circulate the humid air throughout the room.

Also, something called perlite (the little white bits you sometimes see in plant soil) holds moisture very well and if you're growing in a very small room like a closet, get a small basin and some perlite and drench the perlite with water but don't drown it. Just let it soak it up and dispose of the excess water. Give it some heat to release the moisture into the air.

RO water is run-off water. It's rain water that you'd get from your gutters from your roof or something. It's more pure than tap water and more preferred by plants.

perfect...thank you!

I thought RO water was Reverse Osmosis filtered water?

I'm with Pimp on that one. Reverse Osmosis is a water purification process that removes not only nasties, but also most trace minerals, which is why people say you need Cal-Mag when you use RO. Many of the purified water refill machine thingies at grocery stores use RO (at least around here).

You can also get digital thermometer/hygrometers at Radio Shack.

didn't think about that one. my bad.

*switch* for not usin' your dipstick, jimmy!

From 0% to 100%, what is an ideal % of humidity to have for a closet grow room? Thanks!

[fluid69]

50% is ideal.
