Best location to place thermometer/hygrometer in grow tent?

[BurningTeddy]

Recently moved my lights and have noticed a pretty drastic change in my hi/low temps and humidty readings. Nothing out of control but still a decent change from the 78-84° and 40-50%RH I was keeping.

should it be down about canopy level? Base of pots? Above/below light?

should I have multiple thermometers?

where are your thermometers placed?!?

I put mine on top of one of my pots.

I like one on the floor and then one midway(I have a pocket on my tent for it). That way I have medium read between floor and heat from the lights midway. ...a guesstimate.

I have 3 one at canopy level one at root level and one above the light.... it might be a little over board but I know what's happening in my climate and average temps/rh.

I only have one ATM; it's clipped to my scrog net...downside is I have to open the tent to read it which could get tricky after I flip to 12/12.

Yeah I bought one at Wal-Mart that has a sensor I put in the tent and can read from outside the tent 😉.

I use two; one sitting on the bucket lid and and another identical one hanging 2 inches above the canopy. I raise that one out of the way whenever I'm working though, which is a lot.

Chefbjy You could never have enough meters my friend. I'm thinking of putting another one a few inches above the lights as well to monitor the highest temps of the room.

with seedlings and small pots i put it right above the pot to monitor the roots don't get too hot, once they get bigger and stronger i put it above the canopy where the hottest spot is closer to the light to make sure it doesnt get over 30ºC

I use this point and shoot for temp and place hygrometer in tent tool pocket. Kiss

faaaaaaancy... be sure to stick some painters tape where you take your readings to avoid reflection interference

Mine hangs from my T5 fixture among the tops/colas... about 5 inches from bulbs. This kept it in a consistent place during growth as I raised lights. It's the outdoor temp/rh sensor of an Accu Rite indoor/outdoor unit and has the sensors for my controllers taped to it. The display sits in the house where I see it several times a day/night in case something malfunctions out in the garage.
