rdwc and temp questions

Hey guys i'm building a rdwc setup with 3 inch hose for return st the bottom and two inch hose into 1/4 inch hose feed lines at the top of the buckets shooting down.

My question about this if I have all the return lines connect into one hose that returns to the controller will this be a problem as opposed to having three or four separate hoses returning to the controller?


Also in the mean time i'm doing one bucket dwc. My nute temps are 72 I know this is high but how long can I use this before I have to worry about root rot or algae? My plant s roots are hardly out of the rapid rooter so its a baby
 
Read the Root Slime Cure. You can use the tea as a preventative measure and it will buy you a couple of degrees.

How many buckets are you talking about? I run 9 with 2 returns. The buckets are going to want to fill up and gravity is going to pull the water out so I think you should be fine.

thanks for the tip on the tea what I meant to say was 3 fourths inch for the return house n 1 half inch for the feed hoes
 
I use 1" tube for returns and 1/2" for my feeders. I use 3/4" inch fittings and that 1" tube slips right over them and I hold them on with hose clamps. The tube I used was that light blue stuff and it let light in so I put duct tape over it which you can see in the photo.
 
Is the fitting on the controller for the return level above or below the fitting for the return on the bucketS
 
Mine are level. Using water pressure more than just gravity to move the water back to the reservoir. More pressure (volume) in the buckets than the reservoir and the water is going to go to the low spot.
 
the problem you may have is with your pump warming your nutes over time and you can use frozen bottles of water to control your temps in the bucket for now
 
Thanks I am going to put the controller bucket into the closet that is light proofed then crack the lid and blow some air on the nutes....

The main thing i'm concerned about now is proper circulation i'm having a hard time picturing how the water pressure will move the water throughout the system so i'm connecting a many interconnects between the buckets as I can
 
It's all about equilibrium. Hook an empty gas tank up to a full one and open them both. You're going to have 2 equally filled gas tanks in a hurry. Same with water.
 
thanks again bendbrewer im going to test it today. my main concern is only having one return feed back to the controller if it will create a bottleneck. but then again im only running a 264gph pump so its only recirculating every 15 minutes or so
 
if your return lines are all along the floor or all at the same elevation, then hook up all your plumbing and fill the system...wait until it comes to level in all the buckets...once you turn the pump on this level should only change due to leaks, evaporation, or plant intake...with rdwc you create a water table and the water just recirculates under it
