Change the light schedule.
Grow room temperature lights off.
Keeping the lights off temperature within 10 15 f of the lights on operating temperature serves as a safeguard against pathogens especially molds and fungi.
In a semi enclosed environment a significant drop in temperature can lead to condensation and moisture issues in the growroom and on the plants themselves.
If it s far outside of the ambient temperature you ll need to adjust something in your grow room.
Run lights at night.
Evening and overnight temperatures are cooler than daytime temps so it makes sense to use hot grow lights when the ambient temperature is naturally lower.
If you re using hid grow lights and temps are too high at the canopy level say close to 100 f raise your lights.
For indoor growers lighting is all important.
Most cannabis plants start suffering when their temperature gets over 80 85 f 27 30 c so it s important to keep your grow space below that threshold.
Over 60 can mean slowed growth and pathogen risks.
Another advantage is that many electrical utilities charge lower rates during off peak times usually from 7 00 p m.
Room temperature with lights on should be 20 26 c.
The goal is to imitate autumn so temps need to be kept.
I was just going to run the cut off switch for the light because that generates the most heat but i guess in small quantities the ballast air pump and fans generate heat too.
For example in the vegetative stage your plants need 18 hours of light each day.
When you should raise your lights when your grow lights are too close your plants have a chance of overheating your canopy.
For an indoor cannabis grower the prospect of cooling a growroom during the lights on period to the point that it s cooler than during lights off is quite daunting.
When you run your lights at night.
A common mistake is to purchase an air conditioning system that s far too large or small for the grow room.
While it is tempting to use powerful lights too much lighting causes the temperature in your grow room to soar.
Grow lights provide our plants with lots of life giving light but they also produce heat and big grow lights can produce a lot of heat.
Room temperature with lights on should be 22 28 c.
Decrease to 40 50 rh.
During flowering low humidity is important.
