Root rot?

Hey all, checked my roots tonight and my biggest one seems to have root rot above the water in the reservoir. Would this be because of the top fed method? Getting too much water over the roots? I pulled the top fed tube out of that one because the roots are touching the water already. I plan to do a reservoir change tomorrow with a little more hydroguard than I used last time. Will this be effective? Any other suggestions?

Hey mcubed, we need more information: what's your water temp? And the thing that has given me root rot in the past: ANY LIGHT LEAKS? If you have light leaks, the problem will persist. "Too much water" in DWC won't cause root rot.
 
Check for light leaks like alltatup said are u useing dark airlines because my clear airlines were piping in light like a fiber optic cables also what is your res temp.
 
Thanks to alltatup I started using great white and solved the root issue. I have hi temp in res but the combo of hydroguard and great white solved it. Also a little voodoo juice never hurts.😀 I've never had light issues . Baskets packed w hydrostone and reflective tape the tops of the res covers seems to work for me. Hang in , it's nothing but fun when the babies turn into big bushes.
 
The last time I checked the water temp it was around 73. I believe the only time light gets in is when I'm checking pH(I take a net pot out to get into the reservoir, but I put it back as soon as I get the water I need). I have had paper plates over all the net pots (even the ones that don't have plants in them). I also have reflective tape on the tops of my totes.

The reason I thought it was too much water on the top fed part was because I only have 2 tubes that are on. In the other tote I have going, I had turned others on after I noticed my rapid rooters were too wet the first day or two, and there was a significant decrease in the amount of water that was coming out of the tubes that were turned on.

Thank you for your input! I'm about to go check on them right now!
 
I am using clear ones, but they are towards the bottom of the net pot covered in hydroton, with a paper plate on top of the net pot. It's possible the light is still getting in somewhere though. I'll have to check when I go down there.

Thanks for the info!
 
Depending on the manifold your using , you can adjust the amount of water flow by turning the little knobs, mine are orange.I leave them at about half. And oddly I leave the empty baskets going full throttle figure it helps with aeration. Maybe 😀
My res temp is 77 and the same setup .
On your next res change you might try a good cleaning with h2o2 , I found it got rid of lots of slime.
 
mcubed476 I'd put something completely light proof over net pots. Light might be getting in thru paper plates. If you hold a paper plate up to a light, you'll definitely see the light through it.
 
I will definitely get right on that! Thank you! Would anyone happen to know what specifically causes the rot to be above the reservoir water rather than below the water level? I read that it can be either, but I didn't see an explanation for it if there is one

Well, checked the reservoirs and they both had this brownish algae stuff in there. I cleaned out both takes with Dawn dish soap and hot water and thoroughly rinsed both of them out. I also took out the top feeds in both tanks. I plan to hand water the rapid rooters every day to make sure they are damp still. I also added a little bit extra hydroguard than the last time, not too much, hopefully that will all help. I also put reflective tape all of the paper plates to prevent any light from getting in. I'll let everyone know how she's doing after I get out of work tonight. Can't wait!

I don't want to be that guy but replace your clear airlines with uv proof 1s. It looks like u have a real problem there it looks like me res did a month ago
 
Good luck with this!!! I'm also dealing with the same thing in my small grow box right now. I feel root rot solidarity with ya!!!
 
Don't be afraid to be that guy man! Thanks for the info, that is the next step I will take! Would it be cool to wrap the clear tubes in reflective tape?

Howdy mcubed476, I have tried H2O2, Hydroguard, Dutch Masters Root Zone, and GH Florashield to control root rot. None worked as well as what I am doing on my current grow.
First. I covered ALL net pots with aluminum foil, the ones with and without plants. The pots with plants just have a small hole for the seedling which enlarges as the plant stem grows.
Secondly. I quit opening the top of the reservoir to change out the ice bottles. In the past I had to open up the top, exposing the reservoir to light, to fish out the (thawed) ice bottles. I cut out the bottom of the net pot that I use to add nutrients and water. This keeps the bottles from 'drifting' away and allows quick and easy exchange.
I still use the GH Florashield (2ml/gal lower than before) as an inoculant against molds and fungi from starting. I have the cleanest roots and the sweetest smelling reservoirs that I have ever had.
Here's a photo to clarify (I hope).

I think you hit it spot on: light leaks are so often the culprit that's hardest to catch and take care of.
 
That sounds like a hell of a good idea Dw2! I just put foil over all the paper plates this morning. I like the frozen water bottles too! That's a great idea!
