Yes! Yes! I’m glad you asked Burned Haze! Your water should always be about 10 degrees COOLER than your ambient air temperature no matter what type of medium or system you grow in or how you water and feed (DTW)—especially if your reservoir is in the same room. Whether it is or isn’t, a water cooler is always a good idea. If your air temp is 82-86F, with a water cooler you can keep your water (tea) temp stable at 72-76F. I won’t pitch in what brand cause I don’t use em myself. I water and feed with spring water right outta the ground and by the time it gets to my soil its a good 10 degrees cooler then my air temp. A good grow shop will help you out with picking the right cooler you need.
By “good grow shop” I mean a grow shop who will give you good honest advice and not try and over-sell you on an expensive monstrosity you don’t even need. And keep your rez aireated with a couple of good bumblers. Your plants will explode with growth if your tea temp is right and oxygenated!
My new grow shop is a money laundering front for the Hells Angels and they don’t give a fuck about trying to rob your pocket book cause they’re already rolling in dough! They’ve helped me out big time with a few big purchases I had to make. I’m a big non-licensed commercial grower and got stuck in this expensive rut with having to buy expensive auto-trimmers. These things had blades and would jam up due to all the good resin they would strip off my Buds and I had to keep replacing them with more junk my old grow shop sold me. Or at least buy parts and or service for these pieces of shit until I caught on that the grow shop made big money margins on selling them!
A friend of mine tuned me in to an honest dealer who turned me on to a new kind of trimmer that didn’t use blades and was WAY cheaper than these $10,000+ bladed trimmers. It never broke down cause it doesn’t use blades or strip my valuable resin off my Buds! Doesn’t even need any maintenance either—or cleaning! It worked so well we bought 4 more! Its called a Toms Tumble Trimmer. So since I do use these cool simple machines I can recommend them not like water coolers!
Oh, and one more thing, I think CO2 is overrated!
I bought a whole system once and compared the results with several harvests and it didn’t do much improvement. If your ventilation is top notch, you’re plants will get plenty of CO2 in good fresh air!
Hope this helps!
