UPDATE. the left plant is recovering fast. I went ahead and made my own "UC roots" (Hypochlorous acid) and started adding it to my system. I've been wanting to try UC roots for a while but after reading up on it and learning that all it is, is a diluted chlorine solution I just made my own. $5...

I thought that might have been the issue. When the water level dropped maybe the roots exposed to air became air roots absorbing oxygen, like in a kratky setup. But after hearing from people here that my roots were not healthy I'm sure it was just a combination of things. Because I've ran kratky...

I read your post literally right after I added H2O2 to the res. I have 34% on hand from my last DWC grow that I did before I got the chiller (major rot problems). Here's an update. I've got some new roots popping out and the lower part of the plant is starting to perk up a lot more.

I was going along with Current Culture's feeding schedule but after I started increasing the PPM as the schedule suggested the leaves started to turn really dark green and leathery. I read that is a sign of over feeding or beginning signs of nitrogen toxicity. So I decided to back off and keep...

I'm using Apera PH20 meter and HM Digital TDS-EZ from amazon. I was following the current culture feeding schedule, but when I bumped up the nutrients on week 3 the leaves became dark and leather, which from what I've ready is a symptom of over feeding so I backed off and kept it at around...

My plants started drooping 4-5 days ago. the roots look alright, a little browning but no rot that I can see. Water temp fluctuates from 66-68 (chiller). PPM is 190 using current culture veg a and b, coco called and hydroguard, PH is 5.8. The only thing I can think of is shock from rising water...

Can you elaborate on the no waking up? Because they have sprung up when the lights are on for 3 days now. I don't see any signs of deficiencies, so I'm confused lol Here's more pictures. It looks like some of the lower branches are springing up (2nd and 3rd pic).

It came with the pump. It's an ActiveAqua 250gph pump. Every pump I've gotten came with the venturi nozzle. It's the one with a small hole on the side of it where the hose attaches to. This hose runs up above the surface of the water to draw in air.

Well I think my theory is correct. It's only been a few days since I moved the pump to the rights side and the right plant has really taken off and is growing faster than the left one now.

It's just the basic Venturi nozzle and hose that came with the pump. There are other setups on youtube that make much smaller bubbles.

Here you go. It was hard to get a clear shot because of the churning water. You can see the white PVC pipe to the left. I think the small bubbles were being sucked into the pipe and into the left bucket where the plant is.

The plant on the left kept growing a lot faster than the other, and I've been wondering why. Both Sundae Driver cuts from the same plant, they both rooted pretty much the same time, so i didnt understand. Today I think I figured it out. In the control bucket, I have a pump with a venturi valve...

Ever since I saw product demo video by a company called O2 Grow, I've been interested in alternate methods of aeration. The O2 Grow product is just ridiculously priced so I looked for alternatives and a found the Venturi method. I had a spare 250gph pump that came with a venturi kit, so I put it...

What are you talking about? You were critiquing my response to another person on a separate subject. Just because I know the purpose of the different types of rockwood doesn't mean I know why my clone is suffering.

They do not fit very well, which is a strong indicator that they were not made specifically for the hole on the blocks.. The hole diameter on the blocks is 2", the round plugs are 1.5". I mean you can do it (I have before), but you have to beak up some rockwool and wedge it in to make it stable...

I did pre-soak in a bucket of the same pH 5.5 solution I have in the system. Apparently though, Grodan has came out and said that they stopped using limestone in their rockwool, and they are now pH neutral so pre-soaking is no longer necessary. Although I'm sure it's still a good thing to do.

I just pulled the clones out of the system just to check and the roots are growing just fine. I mean I'm not going to be too upset if I loose one of my 2 spare clones, but it would be unfortunate because these are suppose to be cuts of Sundae Driver #19. It would be nice to have as many as possible.

To my knowledge the 1.5 inch cubes are actually meant to go in the round hole on the grow blocks. The gaps allow you to insert the cube without damaging the roots in the process, and allows more oxygen to reach the roots. They make cylinder type rockwool, but they have an open slit down the...
