Might be your cam bro. I got an old 10 mega pixel cam. It just loaded them all. U might have to crop em.Ok got them to upload but now they say they are to big 1.15 how do i down size them
Yeah. The pump originally didn't come with a pre-filter, but I snagged one off of another pump I had. Iv'e been having to clean that filter every day.Lookin awesome Brutus,
Nice root structure, do you have a pre filter on that water pump in the res? You are going to have that thing full of roots soon.
Temps were always under 70. It cold here and setup is in a basement. I used about 1/4 cup of peroxide everytime I topped off the water. Bout once a week. I did notice a little root rot and that smell only when I dumped out the pea gravel. A little rot was more noticeable in the net pot. Pea gravel maybe? I have hydroton now. What else could be done? There were parts of the roots that were white and looked great. I was thinking alack of oxygen thing. Which is why I thought it needed more sprayers. I'm stumped! I'm ready to transplant next ones in flower room but dont know what to put em in. Dirt or the tubes again. F**k!!Hey Brutus, bummer about the roots bro, I was shoping this would work out better for you.
I don't believe it's a fault in your aero system, more of a fault with the water. You managed the nutes well as far as ppm's go but at some point you got root rot (Phytophthora). This is very common and is the bain of hydroponics. Impossible for me to tell exactly what caused this but it's most commonly from lack of dissolved oxygen in the water caused by heat.
From your pictures earlier in the thread, it looks like you have enough aeration in the water so my guess would be the water temps were too high for this aeration to overcome.
First, you need to keep the water in the res below 70F and check your roots often. Root rot can happen even with adequate aeration and perfect water temps so some folks like to add products to the water to keep the res sterile.
H2o2, bleach, or various other products like SM-90 can all help to keep this from happening. Personally, I use clorox laundry bleach at 10 drops per gallon every 4-5 days.
Says 3% on peroxide. I was thinking about drilling a bunch more holes to hit the water and make pretty much all the water in tube bubble to create more oxygen and def use the hydroton, which I know is better for oxygen compared to pea gravel. Can root rot start from the stem in the net?I like sprayers better than just holes drilled in a tube but they still get the job done. When I used PVC with holes drilled in them, I used to cut up a piece of 2" pvc pipe into arches and fix them under the sprayer. This gives them a curved surface to hit that's above water, creates alot more spray droplets...
What strength peroxide were you using? 1/4 cup might have been on the light side.. Try the bleach, it works much better for me than peroxide...
WHat about putting some long air stones at the bottom of the tube? I have a really strong pump!Thanks for your help bro!Yes rot can start from the stem, the hydroton is much better than gravel for aeration. 3% peroxide is much too weak, this is the problem. I was using 33% with about double the dose you were using.
The 3% from the store doesn't work for hydro very well, you need food grade 29% or better but it's expensive in the long run because it needs to be added every 3 days.
This is why I use bleach, a $2 gallon lasts me a year and that includes clean up in between cycles. Make sure you clean that rig really well before next run or the Phytophthora will come back right away..
Drilling more holes reduces water pressure for the spray jets and I don't think it will solve the problem. The more you can get the water to atomize the better with aero, a single jet is all that is needed for each plant. Your rig with a single 1/8 hole per plant would work well if you create a convex surface for the water to hit down by the roots...
Never seen a setup like that. When u say no resirculation, do u mean same water in your tubes? I dont see a inlet or outlet other than the 2 openings on the side with the 2 blue caps. U must have a chiller?? So I'm racking my brains here! Googling my butt off. I have the 4ft air tube also. So far I have been playing and testing. Deciding whether that or more stronger air bubbles would work better. My geuss would be smaller more even air rather than heavier bigger bubbles. I did drill more holes as well inside the 4" tubes as well. I'm also thinking how high the water level should be. I see yours is lower like ntf.
*note the 4ft. air wand...
with no recirc, air is essential to this set-up. Also maintaining the correct temps in the res is crucial.
