How to maintain temps during night cycle

[Bender8982]

Hello there, My question is, how do i maintain a consistent temperature 24/7?
during my light cycle im hanging out around 74-78, then when the lights go off i drop into the mid 60's. i know this is unhealthy, but how do i solve it? Do i plug a little portable heater into a cheap thermostat and put it in my room and then at night when my temps drop it kicks on util it balances out? what methods have you all used to solve this problem? Thank you all.

Why is that unhealthy?

Mid 60's is good, rule of thumb is 10 degree difference.

Insulate your grow area.

You can put your vent fan on the same timer as your light. Then it will not suck in cold air at night. But, then you end up not getting enough CO2 (I think ... not for certain).

Hi Mutt, my fans run on my light timer and while I'm no expert plants seem to be fine. Second week of flower and all sorts of pre-bud action happening. Not saying they couldn't be better, but for what it's worth there ya go.

Mine drop into the sixties at night. I let my fan run 24/7. It gets cold up here where we live. Not much you can do about it. But, it stays at a solid 75-78 during the day.

Why is that unhealthy?

I was gonna say....that seems ideal and quite realistic to me. I get a range of about ten degrees or so and my plants seem rather happy with it.

Seconded. Cannabis is a very hearty plant that can easily withstand your 10-15 degree temperature drop. It's actually somewhat beneficial to the plant because it more closely mimics a natural growing environment. For my two cents, you'll have a healthier plant with the temperature drop than without.

alright guys i feel much better now, this first grow is stressful, im an overprotective parent, i watch these babies like a hawk.

During the winter, I run my lights at night for the extra heat.
Daytime becomes night for the plants.
They don't mind.

In the great out doors there will always be a temp drop between night & day this is benifical to plant as it trickers hormones etc

With MJ temps below 60f/15c may induce plant shock over a prolonged peroid, say a good few days to several & at worst may kill the plant if really bad or prolonged.


I normally have drop between lights on & off between 5c to 10c with plants all being healthy depending on time of year, please bear in mind i grow indoors & ambient temps through out the year may effect indoor temps slightly.


The only thing i've noticed is the smaller the drop in temps between lights on / off, is the trichome developement being more rapid !
