Thx. My main concern was if the 1 1/2 hp chiller could cool all of it. The 125or so gallons im chilling seems to be just right. Im sittin at 68 mid day. The plants seem to be responding they werent all in the best shape going in but they comin around. I figured may as well throw out the other 12 sites and run full capacity. I still have enough room to work. Going to be crazy once they in flower.

Have you thought about site insulation at all?
Could take some strain off your chiller, im sure it produces a good bit of heat.
My veg setup has some heat issues and insulating my buckets cut way down on the chiller on cycles.

Have started with the piping. The kind im using is pretty expensive. Pain in the ass doing all that cutting. There is just so many. Im wondering what will be easiest for cages or trellis netting.

Even this cheap bubble foil stuff for windows that I used made a pretty big difference. I was able to layer several sheets and cut 5 or 6 layers with a single cut once I found the right blade.
definitely will give you something to do when youre standing around going wtf can I do right now lol.
I would probably just make some wood frames along each row and get some rolls of that cheap trellis netting you can roll out every cycle.
Easiest way I can see to manage that much. Just have the netting be disposable so you can cut it out and replace as needed.
Ive seen some people just roll out some of that pvc coated wire fencing over the rows.

More water will take longer to heat up and chillers cool slowly. I would go as big as you have room for up to the max your chiller is rated for. Should be better.
It was much easier to control temps in my 130 system than my 30 gallon system.
I keep mine at 70 on purpose.

That is great info. I'm heavily considering the wort chiller method for my rdwc systems but I'm not sure how large (length of coils or size chiller) I would need. By using this method, I hope to use one chiller for 3 seperated rez's. Each system is 77-83 gallons and are close to each other, with 2 systems in one room and the third seperated directly behind by a wall. Any ideas would be greatly appreciated.

So you think 70 better than 65? Water hold more o2 at 65. Always wondered if the cold water slowed stuff down.

I did something like this to chill 2 systems with 1 chiller. I put a pump in my res that pumped into coils in a bucket in my flower res. Kinda hard to explain. But line came in the side of the res and I split it into 4 smaller lines. I coiled up as much tubing as I could in a 5 gallon bucket and made the return from my chiller waterfall into the bucket first before overflowing into the system. It's all about surface area of the tubing touching water, more coils of smaller line is better than bigger coils of larger line.
I was able to keep both systems that were around 150 gallons at 68F with a 1/4 hp with no site insulation.
Youll just have to kind of play around with lengths and how many coils ect to get it dialed in to your specific heat needs. 50ft of 1/2" tubing coiled up in 65F water was about to maintain a 35 gallon system thatll climb from 65 to nearly 80 in a single day under 70F with no insulation.
This is the only pic i could find, I started witth this end ended up coiling it up in a 5 gallon bucket in there.

For my 30gal rdwc system I keep chiller at 70 with a 2 degree deadband. Chiller will run once every 30 minutes or so

Ive done both. I wanted to know if I could get away with 70 using the southern ag fungicide and it worked fine so I just left it alone after that to let the chiller run less.

Pretty much how I felt about it, but I run sterile with 3ppm of pool shock.

Im using 1 1/2 hp chiller to chill 76 8gallon buckets. Water manifolds to wort chillers. 69 and 70 on the 2 32 site systems and 66 on the 12 site

Probabaly air stones, the UC systems use them.
