OMG pleas help!! mold?

Ok so today i go into my grow room after 2 days of not really checking and as im feeding my plants i notice on the other side of the room mold!!! it was in the corner and spread half way down the wall but didnt go up the wall. I cleaned it immediately with lysol, scrubbed, and dried. Its all gone now and i figured out what it was from and eliminated that. but im scared my plants might get moldy now even though they are in a grow room and on the other side of the mold and a good 5 ft away from where it began.

is 70 too high inside the grow room?

Just a little, I shoot for 60, little less in flowering so I dont develop fungus, have not had a prob yet

60-80 f, 40-60% humidity. plants have defences against mold, but if theres an overgrowth, youre in trouble.

normajean is awesome. you listen to underoath? norma jeans drummer tracked drums on their two newest albums

"as i sink down into the floor..and the walls are caving in..and i dont believe in them anymore. now i try to balance my walk, i am coming down alone, and i have to get them out of my head.."

In my opinion yes. I like 50 or lower during lights on. I get down to 30 all the time. It's kind of a balancing act between optimum growth and mold mildew problems. Given those two choices I'll take a less than optimum growth rather than try to fight a problem caused by humidity, any day.

my RH often drops into the 30's as well...I was worried about it at first but now seem to live with it.

How low of a RH % would you consider to be a problem or concern?

I actually get down to low-mid 20's at times if my grow gets a bit overheated. I have a problem regulating humidity, mine might go from 22 to 60 in a 24 hour period. Your plants will let you know when it's too dry, you will see some wilting, droopiness, and maybe tip browning.

I would much prefer a low humidity problem than a high humidity problem. Low humidity the stoma close down and processes slow. High humidity stuff rots.

Indicas can handle low humidity better than sativas. Sativas can handle high humidity better than indicas. Since most good stuff today is a hybrid they are all middle ground humidity wise, in my opinion.

Low humidity to me is more of a factor in the seedling / small plant stage, when they have small root systems and are not transpiring much water into the grow area, and don't have much of a root system to uptake water. Then they can get dry. Once they get larger with a lot of root and leaf surface the plants are going to be pumping out a lot of transpired water into the grow area and then you might have to deal with high humidity.

JMHO but I am for drier air once the seedlings are soundly established.
