Humidity Question

Just got my humidity therm. hooked up, it reads 66 but the problem is it's not right where the canopy of the plants are. I see no signs of fungus at all, but am considering buying a dehumidifer as a precautionary measure. Question is... if my humidity is at 66 a few hours into their "day" what does it get up to at night? Should I be concerned? I also only have one occilating fan going right now, perhaps I should buy another. Some people reccomend using a heater during the night cycle, others reccomend a dehumidifier to prevent molding... what do you guys think? Also wanted to add I did veg for a little longer than I should have the plants are crowding one another a bit more than I had anticipated....any advice is appreciated.

66 is pretty high for humidty, a dehumidifier would be a purches well spent

It would be a great investment! The heater is just gonna warm the air.With the heater running and humidity high.You are only creating condensation on the walls and ceiling.You need to have some type of exhaust as well.Put a theromstat on small fan.Set it at about 68 or 70.That will help draw some of the moisture out of the room and decrease the chances of fungus and the dreaded black mold! Hope all goes well!

66 is kind of okay for veg but on the high side. I'm vegging in the high 20s -low 30s. Low humidity in early stages is important to prevent damping-off.
For flower it's super important to get your humidity down to 50% or less.

dammit.....but all true stinky.. i like to keep the humidity down to 20-30 % the last two weeks...just to be safe

That's 'cause the Pontiff has big buds
Fluffy sativas can take a little higher humidity if you give them some breeze

i will do something that is a no-no...if it drops to low.. i will spray some ph'd h2o on the plants EVEN during flower...but the pontiff is blessed and knows how to deal with fungi

Shit, sounds like I need a dehumidifier ASAP. I am in flowering right now, and my humidity is down to 62. I will buy a dehumidifier today, and set it so that it goes on if the humidity goes over 50, just to be safe. How much should I plan to spend to have it be effective for the whole room?

Just a plain boring dehumidifier that you can find at any hardware store is fine, I think I dropped $150 or so on mine, and it's a pretty nice one but it is for the cellar, not the flower room.. I'm blessed with DRY winter air ATM!

give me the sqare feet of the room and i will tell you
