Ideal Temp/RH day/night

What is the ideal temp an RH for grow tent in each stage day/night? HELP

Day versus night humidity isn’t so relevant. The best guide to go by is as follows (by stage.)

Just don’t chase rh too much. Air movement is a little more important. Especially for seedlings. Basically don’t sacrifice your fan to increase rh. I never get over 45 rh and many others don’t either.

My rh at day is 60-73 basically the same at night an my temps are 77 at day 72 at night

You’ll need to lower that late flower. Avoid mold/bud rot. Large plants bring up the humidity, def gonna need a dehumidifier.

That’s with a humidifier on when it’s off it drops to around the 30

Oh. Then you should be fine. I stay around 40, quit bothering with humidifiers pretty quickly.

So is that day an night you stay around 40 through each stage of grow???

Yeah. Midwest.

I mean. I haven’t tried indoor in summer here yet. That may be interesting

Wow thought that would be low for seedlings an veg

U should try it


Looks happy to me.
Edit. Looks like I need to raise light, otherwise happy

Everything I know I learned here and from Dr Bruce Bugbee. Youtube him, shares the findings of the hemp program at college in Utah.

It’s really cool that more and more research is being done. Since the netherlands might sell us their seeds, but they don’t share their secrets.
