So I have set up my first grow room with fresh air intake and exhaust. Im running 2 400watt metals and was wandering if I should expect any issues from the tempeture ranging from 70 degrees to 95 degrees. The humidity is running from 26 to 39. Is this unconsistent temperture and humidity going to cause any sort of mold issues or stress to plants?Im only 1 week into it.
I know you should run the temperture from 72 to 76 if possible and the humidity should be around 50. Is there a way to increase the humidity besides putting a pan of water in the room. The room is completley sealed off. Any input would help!!!!!!!!!!!:joint:

IMHO lower humidity is better for resin production,
95 the max u want to go without c02, I try to keep under 90. but you need to be measuring the temp at the top of the plants under the light. I have a probe 4 inches from my glass, and thats what those temps are, my rooms around 75-80.

Generally when humidity is lower your plants will:
Have narrower leaves,
Have a waxy coasting on the leaves,
Denser smaller buds,
More resin production.

so again is that 95 in ur room or under the lights, cause if thats room temp its probably to hot on your plants tops. Have a small oscillating clip fan blowing right on top of the plants.

This is what I have heard anyway. Also a try for no more +/- 20 degree fluctuation, a lil more isnt going to going to hurt anything though.
I Don't think you need worry about it, though I am not an expert and 26% sounds a little dry. I don't even monitor my humid but its probably between 40 and 60 most of the time. Its humid here.
And seconds?
