Benefit to res chiller besides root rot?

    When you dim your HID lights you ruin there efficiency, spectrum, and life. Why not get 2x 315w CMH? Or even 2x 400w HPS if you don't have the cash for the 315 CMH?

    I was thinking about doing the same thing. My thought with this there is o my so .ugh room in 1 tent. It would be difficult to stiff 4 air cooled hoods. Or 2 hoods and 2 cmhs. That's a shit ton of heat isn't it? I am asking because I do not know. I do know the amount of heat the tent has now, it's not much. But if I added another 600 hps I feel like the temps might get out of whack. I know I need more lighting. The one 600 is doing ok considering the load that's on her. At 1ti.e I had 7 plants in there. Not a good idea!:)

    Good point! I've decided that I'll build one on my cob LED lights for half my tent, while running the 600 watt on the other. That'd be until I could afford to build the other. I haven't priced anything for well over a year and a half, so I'm sure prices have dropped, and new products are available.

    Also, didn't know that about ruining the bulb's efficiency.

    Thx!

    Not 4 air cooled hoods, 2 side by side. Using external air for the hoods would keep 1200 watts cool, with a 400+ cfm fan. Keeping my hood air isolated makes managing temps so much easier!

    How big is your chiller and do u know the flow rating?

    1/10 HP. I would have gotten the 1/4 HP but I read in the reviews people keeping 50+ gallon reservoirs cool so I figure a reservoir half that size would be no problem. It's still doing the job, it doesn't get above 70f. I grow in about 40' of 4" PVC so when the lights come on that's a lot of surface area to absorb heat.

    You might think about getting another external pump, and using stainless steel wort coil, to run an enclosed loop chiller. I think you'd be able to remove more heat like that. You could also use another reservoir, made from a cooler so it's insulated, to provide a larger body of water. Water retains temps 4 times longer than air. So if you had a cooler that has been chilling all night, it would have that stored energy to help the chiller during the day.

    Having a fan blowing on the chiller radiator will help the chiller dissipate the heat it's removing from the water. If it's in an enclosed space, your chiller won't work nearly as well.

    Nope he is better off just pumping the res water through the chiller than piping an indirect loop and it would have to be a pretty big loop which would effect flow. All my cooling is done by passive underground loops in colder weather and I'm running 200' of copper under ground lol. Direct water to chiller is more effeicent using one heat exchanger. Just make sure your flow is correct as stated and yes insulating the system helps a lot ;).

    I don't see how adding a wort loop and an additional pump would keep the res cooler, I would think if anything I would be adding a little heat with the additional pump.
    The chiller isn't in an enclosed space but I could put a fan in front of it for the hell of it and see if it can keep the res temp lower while lights are on.

    I am definitely over the flow range of the chiller with a 2100 GPH pump. Running the pump alone adds a good amount of heat, I notice it when I clean my systems in between runs, I use run the pump constant with a bleach solution in the res and that ice cold water from my tap gets luke warm after running through the pump for a while.

    From left to right (call them 1 - 4), here's what they do:
    1 - valve for all the water in the system behind it (all pipes and totes). When I close this, in conjunction with valve 2, I can easily remove the filter and clean it, without spilling a drop.

    2 - serves two purposes. One, when valve 1 is closed, I connect a tube to it [valve 2], open the valve, then I can blow out any remaining water in the manifold. After that, I can remove the filter for cleaning. And second, I can bleed any bubbles in the pipes, that are getting caught in the pump and making it sputter. After opening valve 1, and with the pump turned off, I open the valve, and any bubbles are force out.

    3 and 4 - Used in conjunction with each other to route the water, post-pump, to either the reservoir (the system), or the drain pipe running through the wall.

    I haven't worked will chillers, but I've seen a lot of setups. I was throwing out some ideas, but figured ppl would chime in with knowledge.
    :mad:

    A 1/10 hp is about 1200 btu's I think so yes pretty small so any help you can give would help and yes way over the flow rate and that may be the issue as well as it's probably not great for the chiller as well :(. Here is one I built using a 6000 btu compressor IMG_4344.JPG IMG_4343.JPG

    Nice job on that DIY chiller! I only bought this size because other reviewers said it worked for them with reservoirs twice the size as mine. I don't see why higher flow would harm the chiller, all it is is a titanium coil encased in plastic. I have 1/4 HP units on the way..

    The higher flow is probably not pulling enough heat from the refrigerant which raises the superheat causing excess heat and pressure in compressor so not a good thing. Not sure how u have the thing plumbed but I use a seperate pump for my chiller and it just pulls out and sprays into the res. I have a flow valve to control flow. Your chiller is probably ok if set up right.

    I use the same pump for the aero setup as the chiller. The pump pulls water from the res then it goes through the chiller and into the aero setup. I was thinking about getting a smaller pump but I don't want a cheap plastic pos. Any ideas for a pump smaller than mine but at least 1000gph?

    You could just get a couple inexpensive pumps, like from Active Aqua. They work just fine, and if one breaks, you've got another.

    I actually had one of those I used on my first low pressure aero system, I had the biggest one (1000gph) and there's no way in hell it's half the size of the 2100gph pump I use now. It barely put water through all of my sprayers..
