temerature question

[morgancola]

Right now, my current setup runs aprox. 75-82 degrees when the lights are on, and around the same when the lights are off, sometimes its a lil warmer when the lights are off. Is that OK? Should there be more of a difference between off and on>?


thanks

I try to stay under 80 myself. Around 85 growth is slowed/stopped without the introduction of more co2. I am around 60-68 in the dark period and no more than 80 with the lights on(usually around 75-78). Those temps are fine I'd say. Why is it hotter with the lights off?

The temps you are running now with the lights on are fine. In nature the temps are aleways lower at night but I dont know if a less temperature is necessary. I also find it funny that the temps are warmer with the lights off......

cause the lights are on during the coldest part of the day and they are in a attic where warm air acumulates during the day.
When summer heat comes Im not sure how its gonna work, My intake is tapped off a A/C vent in the house so when the A/C is on it gets cold, like 64 in 10 minutes, so when its 110 outside and 130 prolly ambient, my a/c is gonna be kickin.. This is also a flower room only.. What humidity would be best.. Its hovers around 30 or a lil lower when the a/c is on//

thanks

30 is fine for flower

 

[morgancola]

Cool, Its 76degrees right now and 45 percent.. We have a system overhead.. When the lights kick on.. itll drop to 30's

45 is fine for flower too you dont want your humidity getting high, yours is in a good range.

I have had "night time temps" that exceed my daytime temps because my grow is in a tropical area and in a attic. It might not be a good thing for plants but it has worked fairly well when my night time temps do not exceed 95F * when I exceed this I get hermies/stressed plants but temperatures below 95F at night and 80-86F day temps I get close to normal growth and flowering. My humidity is 25-40
Good Growing
