Grow Room Temperature Lights Off

Grow room temperature lights off.

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. Run lights at night. During flowering low humidity is important. 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.

Another advantage is that many electrical utilities charge lower rates during off peak times usually from 7 00 p m. 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. If you re in a situation where the temperature is climbing too high at specific parts of the day then you can change your light schedule so that your grow lights are off during the hottest part of the day. 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 should raise your lights when your grow lights are too close your plants have a chance of overheating your canopy. For example in the vegetative stage your plants need 18 hours of light each day. As a result frequent fluctuations play havoc with the temperature. The goal is to imitate autumn so temps need to be kept.

Room temperature with lights on should be 20 26 c. For indoor growers lighting is all important. 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. While it is tempting to use powerful lights too much lighting causes the temperature in your grow room to soar.

Room temperature with lights on should be 22 28 c. Change the light schedule. A common mistake is to purchase an air conditioning system that s far too large or small for the grow room. 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.

I wouldn t want to turn everything off at say 85 but if for whatever reason it did get to 103 i would want everything 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. If you re using hid grow lights and temps are too high at the canopy level say close to 100 f raise your lights.
