Cant get my humidity above 18%

i have a digital hydrometer that i cannot get to read over 18%. i have my hydro rezi and wet towels and bowls of water in my closet yet it still will not go up. should i just go buy a humidifier or am i doing something else wrong?

i would by a cheapo analog meter at the store first before you spring for the humidifier. Make sure it's not a problem with the coil in your digital one. Also, I would go ahead and get a little room-size humidifier. They only cost about $15 dollars and they are much more efficient than the bowl and towel method.

Do you have plants in your room yet? My humidity was really low before the grow, but after you get some growth and transpiration in there the humidity naturally goes up. I think I had around the same humidity as you, now it gets up to mid 40's%.

Ever think that your hydrometer is inaccurate? It's only a machine, after all. Not infallible.

Just do it buy a humidifer

How old are your plants. Early on you want to keep it humid, but after they have put out the third or fourth set of true leaves the low humidity shouldn't be an issue. Once they get bigger they will be releasing so much water you will be trying to lower the humidity.

Yea that's what i was trying to say, if you just started the grow you should be fine.

ya man definatly dont sweat the humidity too much right now. once the plants get bigger you will be fine.

thanks for all the info, right now their just seedlings so i was worried about the humidity being to low, but the second set of leaves are just barely starting to come out soo. Even soo i was at walgreens and bought a humidifier for 20 bucks and raised it to 25% overnight.
