Water chilling is best used when it is fully integrated into your op. If you have two bloom rooms, plumb them both, then run them on the flip. One chiller cools both rooms, with a quarter to half the BTu output of the AC you'd need. A flip setup is where water chilling really shines, because one unit can be plumbed to cool multiple spaces.
First off THANK YOU for all the
specific, clear information that you kick around this site, while i appreciate the massive amount of knowledge that flows here so much of it is "here's how i rigged it for me" and does not really get to the 'do this ~ here's why' part of the lesson. Also i can't help but like the fact that your a fellow Colorado grower, because nothing else even comes close to actually growing in Colorado, our conditions like everyone are unique, out water is so good here in Boulder that tap feed plants often beat up on the Filter watered ones,..........hell we pull 65ppm water out of the Tallboy filters and off to the races!
I hope you can give this one a shot i'm busy reconfiguring my space from one sealed 10x12 room into two,......and want to run it flip style with 4k on each side, the limiting factor has been my summertime day time temps as i have been running 4x1k in the room with the lights vented in a loop,......temps hang at 83F during the lights on cycle if i run them at night. Nowi've upgraded the lights to a 2 light loop with a fresh air intake to each of the pair of lights, as i'm sure your quite aware the night time air temps here are very rarely above 75F so this has worked very well ~ But i'm going back to my 8gl bucket UC setup with 18 buckets under the 4k and will be running a chiller for the UC, since i never needed to run AC in the space im wondering what thoughts you might have reguarding a setup where the temps were so vastly different on an AM/PM shift. my biggest concern is keeping that second room below 85F in the day time half of the flip, mostly i guess i'm worried about the temps of the room getting additional day time summer heated air to vent the hoods and the needs for a chiller strategy to beat it.
My set up ideas so far are to use a 50 galon barrel to hold water that is chilled directly by the 1/4hp chiller ( i was thinking of holding it in the mid fifties but now wonder if thats too cold...) and hold the UC nutes at 'temp' using a 25' or 50' SS coil run to the epicenter, i'm thinking i would need some kind of therm or temp switch to turn on the pump when the UC nutes got above 65F and circulate the cold water in the coil back into the UC to 're-chill' the nute water,......The main reason i wanted to run that 50 gl bucket at such a low temp is i wanted to use another SS coil to chill an ICEBOX type of chiller and cool the air directly but a) i'm not sure how many ICEBOX units i could run in a loop this way
b) what real effect the ICEBOX units would have on the RH in the room
c) or if a strategy exists to cut out the venting of the hoods and use the chiller to completely cool the space,......( i understand the need for a much larger chiller for anything more elaborate than chilling a 50 gl bucket and SS coils)
Thanks again any input would be very appreciated, and keep up the good work! I'e lurked around a few of your threads and you really do have some fine genetics, and great technique representing the Emerald Rectangle!
