33 degrees with lights on, down to 20 with lights off

Hi guys.

 

im currently starting week 5 flowering stage. With 400w lights.This is my first grow and Im struggling to get the temp below 33* with the lights on. It drops down to about 20 when there off.

They seem to be flowering decently under the conditions but they have started to look a little stressed the last few days. 

Ive got a decent air intake and outtake but they just can't get the temp below 33* 

ive also noticed a bit of a musty smell after watering. 

 

What are major issues I need to look for now with the temps being this high?

 

Thanks

No, it's below the lights. About half way up the hight of the plant. The soil temp is around 29*/30*

Are you running your lights during night time? That pretty much sorted temps for me this year, lights are on 8pm till 8am

 

Shouldnt cause too many problems at them temps, buds may be a bit airy

You need to take the temperature in the shade otherwise you will get a false reading.

Edited, I misunderstood what you said.

 

 

For clarity.  He means your sensor should be shaded from direct light.

 

 

Not in the actual reflector.

Still about 31*. Do you think this will cause much damage?

 

the weather seems to be cooilng down a lot in the evening this week so that will give them a bit of a break. 

 

The temp had been perfect up until around about  the last 2 to 3 weeks.

As above I don’t mean put the sensor in the light shade, what I meant was you need to make sure the sensor is in a shady area.

Yeah. I garthered that. It’s still about 31*

Ive got a cooking thermometer and put that in the  soil. It’s a few degrees colder than the air temp.

 

Im just concerned that this may be causing  future problems .  Everyone goes on about not having the temp correct. They’re still growing. Just not sure how this extra heat is affecting them.

 Is there anything I should be looking out for and how will this effect the final result?

@Bushmat open all your lower intake vents, it may well be enough.

Toke...

I haven’t got that option..

 

im just interested in knowing what issues this will cause? 

If it’s not going to cause that much I’ll just ride it out. 

If it could potentially ruin them. I better start thinking about some sort of Cooling method.

Ruin them, no. Sub-optimal, probably. Where are you exhausting to, same room? Those temps are high for just a 400.

Got much headroom to play with?
