Humidity question

[blacksaint]

hi fellas,

 

I bought a Spectrum thermometer/hygrometer recently, and have been using it the last couple of days.

(I have not measured humidity before).

Temp readings are fine - averaging around 26 degrees, but the humidity readings are 90 -95%, lights on or off. I have the meter on the floor under the canopy atm, which is quite thick. Is this a reasonable reading for this area of the room? From what I understand, I don't really want to go more than about 60% humidity max. Is this correct?

I have an oscilating fan on 24/7, centrifugal fan and filter, and the room always 'feels' clean and fresh to me.

 

Where's the best place to put it? I was going to hang it from the roof so it hangs just above the canopy, but I assume I would want it out of direct light.

 

Thanks.

not sure but i reckon directly below the canopy i'd expect hell high humidity like you have from transpiration. i'd prolly check the humidity of the air flowing onto your plants if you gemme, so away from your light. buy not too sure...

yeah thanks for the reply souljah,

 

I'm gonna take a few test readings around the room tonight when the lights come on, and see what I get. Will probably get back to ya's then.

 

Cheers.

Is this the one with 1-2m of cable then probe on the end? I use to just sorta sit it on top of the canopy, get the best temp reading then imo. When I get started up again think i might have 2 one inside and one outside of room for comparison.

 

I don't think it should hurt having the probe under the light as they are ment to b put outside ya window so u can get indoor and outdoor temp reading (if u got the same one im thinking about... has button for indoor/outdoor temp and min.max. temp and humidity?)

If your still vegging I dont think it really matters how high your hummidity is but pretty sure around 80% is optimal..... then first half of flower around 50-60% is good then ya last half try get it down around 35% to help prevent mold and also MENT to help make ya buds more crystally.

yeah thanks chunknugs.

 

The unit doesn't have probes - it's a standalone job, with a min/max readout.

I'm 14 days into flower, hence my need to get a handle on what my humidity levels are.

I think I'll hang it in the canopy, and shade it with a couple a leaves or something, then do the min/max reading after the next light cycle.

 

 

Cheers.
