hi guys

been told that temps above 85f stunts bud growth

i have a 600w dimmable hps air cooled in a dr90

what i was wondering is what would be better for yield and quality...

600w at 89F

or 400W at 80F

thanks guys
 
Always the 600 at 89. You can offset the heat stunting my using a co2 bag. Co2 allows plants to grow healthily at higher temps. I've heard of guys growing in the 90s just fine. Just watch out for nut lock out and whatnot you should be fine.
 
hmm i have a dr90II too with a 600 ... do you vent the hood seperate from you filter? i had my filter inline .. filter->fan->light->exhaust and had hot temps had to the light seperate from the filter

happy growin
 
thanks ghuys.....so tell...do you have two fans running?

i currently have carbon filter->fan(vk125)->light-> exhaust
 
yes mine are in->fan->light->out and filter->fan->out ... works for me to keep temps down hope it helps

happy growing
 
I've had temps at the plant tops as high as 95 and the only problem I have seen is an exponential increase in odor.
 
3 1K lights over the girls on a 4x8 table. A couple even tried to grow into the hoods. I had to keep moving them.
 
Really?! 95 degree temps lead to an increase in odor? Maybe because it so stifling that the heat brings the odor out more pronounced. I am from the dez and we deal with 110 + degree heat all the time. The biggest sign of heat stress is internodal and stem elongation. I would bet that the plants that have no issues with 90 + degree heat are sativas maybe even equatorial sativas.
 
i have to agree with you there MurshDawg, sativas seem to be able to take it a lot better .. but i like indicas lol or a mix with higher indica percentage .. they dont seem to like anything above 80 it seems when i grow them lol maybe its just me lol

happy growin
 
Try Caribbean hurricane its a saliva that does really well in 97-98°f weather oblige in cancun and it gets fucking hot here... my plants grow great!
 
im just hoping to find a strain that will take cooler temps .. like say 60 f at the low end and 71 at the high end .. but no such luck so far lol
 
That's about all I grow, Sats or Sat doms. No big internodal spacing tho. Yes, the hotter it got the more it smelled outside the room. Between 80 and 85, it was no problem, over 90 and it got smelly quick. It could be smelled down the driveway.
*edit* I let them get down to 40ish in the winter, as they tend to get a bit purple then.
