Sounds good I’ll just leave the water temp as is and hope for the best !
I’ve found the recharge (or equivalent) + hydroguard does seem to work to alleviate the temperature concerns if used from the beginning of the grow as a preventative measure.
Have been running between 72-74° mostly for my latest grow without issue (haven’t looked in the res since day 3 but haven’t had any need to either).
Removing the small square trap door at the rear of the unit and circulating air in through the bottom has helped me to keep the res temperature lower; if that door is on more heat might accumulate down there.

Forgot to mention something in that last post.
When I do a drain/fill I use 2x 4L distilled water jugs plus a bit more - the unit fills with roughly 11L after the initial 12L, not all will drain out on subsequent drain/fills.
The thing to mention is that in my case one of those jugs goes into the fridge overnight (gets down to about 54°F that way) and when mixed with a room temp jug (plus about 1L or so from a 3rd jug) it lands around 62° at the time of filling. I dump all of this into a single bucket and make sure everything is mixed well first.
That relief doesn’t last long but it does seem to help; my suspicion is that it’s long enough to stunt or stop the bad bacteria from establishing a foothold. Either that or the beneficials are just that strong.

Hygrometer middle center please and more air circulation around your unit

Love the shotgun, but be warned, firearms near cannabis might just be super fkn illegal. Check your laws and make sure you are within bounds. I’ve taken my many risks in life with my beloved plant, but I’m not going to fkn prison for her or anything/one else

The weapons are for hunting and hunting only , those are all guns given to me from my dad and his dad . Thank you for the advice.
Brother, I take all our constitutional rights seriously!! I am of a military family who has trained with various weapons since the age of 5. Father is airborne ranger sniper, brother is a Blackhawk helicopter pilot, who is now working on fixed wing, sister is a boom operator (fuels fighter in mid air) and so on. Didn’t mean to offend, just wanted to give you a heads up as laws regarding growing cannabis and having weapons around your grow differ from state to state. I love my guns too

Water temp is about 73 and inside temp is about 89 I opened the door to see if it would cool off , I did throw some recharge in and made sure my ph levels were also good .
My water temp has been about 72 to 74 , and everything seems to be going fine . Nothing over 74 . She will pop anyday now .

How long has that seed been germinating?
Also worth noting that some folks opt for a water chiller to keep water res temps in ideal ranges. Some Grobo owners get by without a chiller. After doing a lot of reading about this the general consensus among scientists and institutions of higher learning as well as accepted science amongst growers.
62-68°F (17-20°C). Above 72°F (21°C) and dissolved oxygen (DO) dips too low. Below 60°F (16°C) and plants tend to slow their metabolism as they “think” the season is changing. Some growers use this to their advantage and reduce nutrient temperature towards the end of the flowering stage to aid in ripening.
Might be helpful to answer some questions you may have about temps and DWC Just4Growers

Hey James, the water temp stays about 73 , or 74 nothing over 74 . She just popped out today if you look at my ilgm strawberry kush feed. I really dont want to buy a chiller if I dont have to 
@Bplatinum9 said or someone said they put a small fan facing downward and it worked out just fine at 70 degrees but I dont have one …
