    It depends. It looks like you built an Under Current, with the big pipes, in which case no, that pump would be much too small. You generally want 12 full cycles/hr. So, 40-gallons x 12 = 480gph pump. I'm really buzzed, so my logic might be fuzzy LOL! But, this is the correct requirement (12 cycles/hr).

    If you're going to get a big enough pump to qualify as a UC, then you do not need an air pump and stones. Instead, you would make a "waterfall" which sprays water down into the reservoir, creating DO in the process. The current is enough to get that dissolved oxygen to the inner roots.

    If you just want to recirculate your nutes/balance water, then you'll have an RDWC, and the size of the pump will determine how long you'll have to wait until the system has recirculated once or twice, and becomes balanced/mixed. With 40-gallons, and an 80gph pump, you'll have to wait a half hour for a single cycle. This would probably drive you nuts, having to wait to see if further adjusting needs to be done.

    If you decide to go the RDWC route, you will need an air pump(s) and stones to provide DO to the roots.

    Hope that helps :)

    @JSB99 thank you for the reply.

    I need to clarify a few things. :)

    I actually have a 500 gph running. But I made a plumbing mistake. I did not figure in the length and size of plumbing. It's flow is slow because it's pulling water through 14 ft of plumbing. So I really need a 800 to 1000 gph pump. This pump will push more like what my original thought of got should be.

    A little more on this build up......

    I have 4 inch air stones to go in the buckets and I alsoo have a bubbler in the res. I also h ave a waterfall setup in it as Well. The pic sucks but here it is. 20171108_152427.jpg

    If your running low pressure sprayers and your spraying 80 degree water on your roots you are running the risk of rot....well I did and got it with a vengeance lol. My root chamber was so warm that the roots basically turned brown and died in two weeks. I added a chiller and sprayed every 15 min. to bring them back. Also I've found that running cooler temps kept things more stable and better root growth. I would think that would correlate into better plant yields.

    No chiller is outside of grow room, everything else is already insulated, even the 4" PVC that I grow in is. I know the pump adds heat. I was running 1 min on 5 min off (aeroponic system) but the roots pretty mush stay submerged after the plants are mature, if I run the pump constant the reservoir temp increases so I didn't even try it until I had a chiller. It is an external pump but it is a big one also. I think its a 2100 GPH, I may try to find a 1000GPH but I want one that is built good not the cheap $50 ones.

    Looks awesome!

    I've got an air pump and 4" cylinder air stones as well. I wouldn't bother putting one in your res. It's pointless after the waterfall. I'd use the extra pressure for the stones in the buckets.

    I've got a 50-gallon RDWC. I was originally going to use less water, and my water pump was adequate for a UC. Then I switched out my 4 x 5-gallon buckets for 2 x 27-gallon hdx totes. So I almost doubled my water content. But everything's working great as an rdwc, and I can recirculate the water in 8 minutes, with a 400gph pump. It's a little slow draining though. May upgrade someday.

    I originally had a little shelf that the pump sat on. Now it's suspended by the pipes, and it's way more quiet! Kind of hard to see down there.

    Nic

    Nice setup!:) I did not think about keeping the res out of the tent. I have any idea! I have the next few days off so I'm going to tweak a few things
    Then. I'm digging all those shut off valves you are rock in on that setup! I need 1 for mixing nutes. I am also contemplating a auto top off setup for this rig.

    Here is my other setup in a 4x4. 20171113_132731.jpg

    These ladies are goin in here. 20171113_153853.jpg
    12 days young. 2 on the left are light of jah and the right is bianca. 3 of 4 topped today. I knoe they are leggy. New type of t5 light (for me) I was playing with. They cannot go in my DIY because that tent is stuffed ak47s in dirtt that are about to be harvested.
    I now know that the viparspectra lights are below ok. But this little 300 full spectrum is better than there 450 reflector is. I used 1 per plant and the 1st pic was a full led grow. Not impressive but it's over rated led. The plants were small but they have 10-16 small colas each.

    Looks awesome!!

    One thing I noticed that might help, is your scrubber placement. It does a lot better at the top of the tent. What you're doing there is sucking the warm air down from the top. You also want it up top so that fresh air, coming in from the bottom, passes through your plants on the way up, giving them fresh air, and cooling them. If you already know this stuff, then ignore me LOL!

    Also, keeping the res out of the tent is a huge help in maintaining temps! Also gives you a lot more room in the tent. And finally, you can get a much bigger reservoir, also helping to keep temps down. I didn't run a chiller this summer, and my temps stayed @ 68! I was hoping to avoid getting a chiller, and I'm pretty cconvinced I won't have to.

    Brother, I will take as much advice as I can. Thank you for pointing out how it functions better the way you mentioned, it makes perfect sense. I put it there because I cannot get the fan to stay on the filter. I will hang it and I'm going to place the fan out of the tent. Is that an acceptable idea? The only thing hanging from the top is a little light that's gonna change too. I am open to suggestions. :)

    Only downside is that you have to cut the tent. But it's cheap, so who cares LOL!

    How about these for resiviors? 2 55 gallon food safe containers! I scored them for 20 a set.... 20171108_152444.jpg

    I would plumb it through one of the vents.

    I have all my fans outside. They create heat as well, so having them outside helps you manage temps. Check out my grow room pics. I draw air from under the house for my light air intake source, which is a huge help! Using all these methods help keep the water temps down, as the ambient air is cooler.

    HELL YEAH!!! LOL

    I would just use one though. You'll only be able to fill them up so much, unless you either have your buckets raised, or the barrel lowered. You can get totes really cheap though. They're around the height of the buckets. You're trading vertical for a bigger footprint though so if space is tight...

    I will definitely. Yeah my electric lines and ventilation need some love. One upside to my large tent. With the shit I have filling my temps are stable 75-80 deb. I need/ want another hps I think. I am on the fence with lighting. I saw the difference and I do not want to waste anymore money on led for now.

    Space is no issue. I want fresh potable water. We have super hard water where we live. 2 55 gallon drums is a over kill. I am actually going to use 1 for a recycling bin. I have a r/o system with an auto fill on the barrel.

    This is where I took a left turn. I was thinking of using the barrel outside the tent and running my fresh lines trough the vents to the main res.

    One thing I'll also point out is that I don't have anything insulated. If I put the lid on the reservoir, my temps will shoot up to the mid 70's. The lids traps a lot of heat and moisture. I just decided to keep mine off. So far, I haven't seen any issues with it. I have a little fish net to scoop up any debris or hairs, but really, I haven't needed to use it.

    I was just chatting with someone about my lighting. I'll post it below. If you've seen pics of the inside of my tent, you'll see that I've got 8 x 23 watt cfl's in the corners, for supplemental lighting. The light drops off a lot in the corners. 1k watt lights cover the corner much better, but with many challenges. Running the cfl's adds heat to my tent. Don't be fooled, cfl's do get hot. Specifically, that mini ballast. That's not what
    T I want to be doing. I want to contain all the heat from lights with hoods. What I've got below should fix the issues...

    "What I'm going to do for my next upgrade, is to get another 600 watt light package, then have two 600 watt hoods side by side. It's not to provide more intense light @ 1200 watts, it's to run them @ 300 watts each so that I get a much better spread, and I can get the hoods much closer. The fan I have will easily handle that."

    I was wondering what you meant by not being able to keep the fan on the filet. Were you trying to hang them together? To do that, you need a strong collar. It's better to use flexible duct and hang them separately. Way easier!

    I cut my tent and have no regrets. They're cheap, and I doubt the resale on used ones are very high LOL! Go for it!

    I wouldn't cut through the vents though. Cut through the tent material. It's way stronger, and I find that the micro vents work really well.
