Water chiller

I’ve never had a problem with my chiller. If anything it has helped me with many successful grows. I had a few months where I was planting seeds and evey time I would get root rot. My res temp was too hot. The day I added my chiller, everything changed. I’ve not had a single case of root rot since, and no other problems either. So it’s up to you, but I’m for them even though they are spendy :+1::v:


I found a chiller for a really good price , I’ll be ordering it on tuesday . I bought everything except for the chiller . So I will be purchasing one . Just I’m not spending 400$ on a water chiller when our resivors are not that big , 190 to 250 is okay , 300 and 400 that’s just way out man …

Great find! Hope it works well and lasts. I agree, water chillers are over priced for what they do. Just another reason I prefer soil :joy::joy:

I have decided after this grow in the box, I will be using her solely as a mother chamber. I’ll get some sick genetics :dna: and go on an extend run of something like Platinum Dolato

That will make the price worth it in the end :joy::joy:


How’d this chiller turn out for you? I’m returning the cheap generic one I bought.

Ordered my Grobo and waiting on tracking. I was thinking of purchasing the Water chiller you have in this pic. @Ray2nasty

I was wondering if it works well?
Would you recommend it?

Please let me know any info helps.


Keep in mind that adding a water chiller voids your warranty if you purchased one.


Didnt work had to send it back , dont get one if you dont need it I didnt need it . My water temp stays at 73 to 69 . ! My room stays at 70 … if you really need to get one you’re going to have to spend the money and buy the good one !


Could you please share where you found this info on voiding the warranty?

It falls under the third one where it prohibits modifications, adjustments or alterations.
Not just my opinion the company has confirmed water chillers fall under this umbrella.

Thank you!


Thank you @Ray2nasty.

I was told to use a water chiller by Grobo so that’s crazy it violates the warranty. Will not be using one.

I will have to just have my room on AC and dehumidifier.


Keep an eye on the plant honestly , discoloration in the leaves , or if shes droopy, or even slime on the root for root rot , best bet to deal with tempature is recharge , its awesome at protecting roots and giving you’re plant the boost it needs ! But in my.opinion grobo is pretty solid , so I would wait and not waist money !!


Just wanted to confirm what @Sweet_Leaf said. A support ticket I submitted came with the following advice:

" Clients on AllGrowers have had success using either Recharge or a water chiller to reduce their temperature. These are some of the products they’ve tried, however, please be advised that they can be pricey"

It also included links to Active Aqua and the cheapo Chinese GeekTeches.


Recharge reducing water temp? I believe they meant Hydroguard defending against bad bacteria when water temps are high.

I absolutely love the Active Aqua chiller. Worth every penny.


Someone at support claimed I had root rot (which I don’t). The recharge was for the said root rot and the chiller for prevention. I just find it conflicting to recommend a chiller, in an offhand sort of way, and then the addition of a chiller voids the warranty


Yes that is not a good business practice to say the least.


It’s a 30 day warranty lol … good luck w that…
