Frozen water bottles can be a great fast fix to get your water temps down but regular use can cause ph fluctuations and bad readings! 
Please find a more permanent way of dealing with the heat.
I’ve attempted all of those methods except the water chiller investment. May just be too hot to run during the summer based on My geographic location. Thanks @Bplatinum9
Sorry! If I think of another way I will be sure to repost!
i had some success using #1 and #8…it was minimal water reservoir temperatures improvement (2F-5F degrees) but still helpful
the water temps lowered when the back of the unit was faced outwards in order to improve air flow at the lower back panel and rear fans…i added a small fan by the bottom opened panel too…i keep the unit like this against the wall now and spin it around only when I need to get inside …everything is looking nice and cool so far 
i’ve added frozen bottles previously but would be cautious as it caused ph fluctuations and made my plant’s stems turn “purple”
Thanks! This could be very helpful for someone running out of options!
Yeah thank you all for the great info! After moving my Grobo away from the wall I pointed a fan in the direction of the Grobo and so far so good! I have noticed that the temp inside the unit has lowered by a significant amount.
I’m fairly confident my hygrometer is broken because it does not feel any warmer than 80° inside my unit where my plant is currently sitting. And the roots and growth rate has come back tremendously, might I add.
Thank you all for your assistance! My lady is back on track and the light has remained on. I have a fan oscillating in my grow area that has helped the unit keep cool. 
Today, before LST. Plant vigor has been restored
Just after LST:
coo 
Looking 
good!
Thanks B!! @Bplatinum9 I appreciate your help so much. Always working towards improvements and your help is so useful.
Looking happy right now, did some trimming last night can’t wait to see how she looks in a few days. Veg is in full gear!
Always happy to help !
My 5 Sour Kush Autoflower’s are this size.
She’s almost hit the second fan! The stretch has begun. I’m gonna let her ride for a bit in early Veg while I’m away for a week. She’ll get more nutes in a week
Here’s how I found her after this last week being away! 
Absolute explosion! Transition begun yesterday. Drain/fill tonight!
I really like how tall she’s gotten 
she’s pretty 
probably a big producer too if she keeps bulking up like that
I sure hope so! At this point I don’t want to do much more pruning but I’m afraid of lacking dense buds… maybe I’ll hang the light from the underside? 
also hang the fan under it.
I’ll have to stare at her for a while and let her tell me what she wants 
that might help w/ stretching too. She doesn’t seem quite done there at all…
