you need to have your system on a timer. Their is not enough dissolved oxygen in your water the only thing saving your plants is the hydrogen peroxide, which isn't the best idea. Trust me I have grown trees using ebb flow systems and they have always been using a timer.
Only when you stop using that H2O2 will you know if you actually are getting enough oxygen to the roots.
Do you understand how dissolved oxygen works?

Yeah I have to agree, they look overwatered to me, mine looked like that when I was doing 4 cycles a day, took one out and viola, all leaves nice and perky.

the more air the better. less water mean more air. you can pump water into the air. but take away the water and more air. So why not use a timer? explosive growth if you do that. you got the setup why not use it. if not throw in an airpump to the table. do that anyway to the res. way more fun. dont re invent the wheel. a little something i learn the hardway everyday.

i think he just wants an argument.. let him win ... and by doing so he will lose when the plants dont yeild as much.

he asked for advice, you all gave it and he wont take it... so let the plants drown..

rooted in rockwool, then in growbags withe 2" gravel and 3" stg media flooded to 3.5", I have a timer and have always used it but I am seeing better growth the last week running 4 hours on and 8 hours off.

my light comes on at 8pm and will post pics cause these plants are in no way overwatered.

Previous I was running 15 min every 6 hours.

This can only be done with fully rooted mature plants. Also media and depth of flood matter.

Do you comprehend the idea of dissolved oxygen, as these fellows do not, your lack of pratical hydro experience:shock: just lends less weight to your opinion:-o...

Have fun smoking the dried leaves of your dead plants then because that's all you going to get with this type of thinking.

They do look slightly overwatered, but if you think that it is working for you keep at it.

Just take into account that plants will grow faster as they get bigger. So when you switched to flooding them longer they may have just been increasing growth exponentially normally and your change did absolutely nothing. Well not absolutely nothing, because your plants are showing signs of overwatering.

So my suggestion to you is find a middle ground between what you are doing and what everyone here is suggesting. Try lowering how long the intervals of flooding are every day until you see a positive change in your leaves. This way you find the perfect intervals of flooding for amazing growth.

Anyways that is just my 2 cents,

EDIT: Also I just read the thread about Heaths Vertical grow. He says in his own words exactly what your problem is: "DWC would typically have an airstone in the bucket to provide Dissolved Oxygen (DO) this system relies on the fast movement of the water through the tubes to provide the DO so there is no need for airstones airgap or other means of providing DO. The key to all my grows is the fast recirculation of the water."

Maybe that tidbit of info can help you out.

Hence the 500gph pump feeding the 4gal tub + the airstones

That is true however somewhere in your system the water is not giving enough oxygen to the plants. Find out what that is and you are golden.

dude your pumping that water through what looks like 1'' diameter hose at half the rate heath is and in 1/4 the volume. water pumps remove air from water but I bet you know nothing and everything about pumps also. your the only one here that isn't comprehending chompei.

If there is no air exposed to the fast moving water it will not become aerated. also solubility of gas into water Oxygen is a gas. is not stable and it is ver easy for oxygen to leave water and not easy to put it in. You hoses are small and there is not enough oxygen exposed to your high rate of flow for it to become properly areated. and the airstones in your res are doing nothing because the bubbles don't stay in the water after the point of pick up as water pumps are not also air pumps. If you cannot comprehend this then there is nothing I can do to help you.
