waterfarm woes

[bendoslendo]

What likely happened is your root system was damaged by dehydration, that's what it appears to me to be anyways. The high water temps couldn't have helped either.

I had something very similar happen to me recently, only with 8 plants! I have an Ebb and Flow bucket system. I set the buckets up on 2" risers before the root system was large enough to be sufficiently saturated by the floods. I'm guessing about 1/2 my root systems died off before I corrected the issue by lowering the buckets again.

The day after raising buckets I noticed a very similar drooping followed by necrosis on the older leaves, just like you've shown above. They took almost a week to resume full growth. They have to rebuild the root system before they develop any more foliage. From the looks of the new fuzzy white roots popping our of the RW, your on your way.

Rot spreads pretty quick so thats the best way to tell if it's present. If all your roots keep dieing after emerging and they are being watered sufficiently, it's likely a pathogen. It's quite possible the dead root is just a dehydrated/dead. Root rot can look like dehydration symptoms as well, as partially rotten roots can't provide adequate water above.

jm420's advice about running the dripping 24/7 doesn't sound terribly bad. I've never run this system (looks like waterfarm-type to me) though or even drip for that matter.

well if your bringing your war i'm going frost. spell reflect all my ice lance spams you want, you won't get within 15y for more than .5seconds..... lulz we are teh dork!

My mistake I thought the buckets where higher than the rez

I dont know who claims this to be like a water farm,Its not even close ,I consider it some kind of eeb and flow excrpt the fact is you top feeding,instead of flooding.

Ebb and flow? Where's the ebb? Where's the flow? Neither of those conditions exist here.

The only "significant" difference between this and an official Waterfarm is round buckets rather than square and the drip ring previously mentioned.

Freezerboy congrats on getting 9k posts ... you are a posting machine xD

I will be installing the drip ring when i get a chance, im clueless as to why the setup didnt come with one in the first place, only being able to water 25% of the surface area as opposed to 100% seems silly to me. For now i have moved the waterflow off the rockwool to water in two places (to the left and right of the cube).

I think bendos is right though, not about his mage pwning my warrior, (lolol ;-) ) but those roots that were in the picture were in a location where when i moved the waterflow off the rockwool cube recieved 0% of the waterflow. Good news is that while the edges of the leaves are turning yellow still, the plant has over night had some significant growth and roughly 20% of the leaves have picked up some perkiness :-D

I am going away for the weekend and should be back in a couple of days, ill post an update when i get back but its looking good so far imo.

thank you so much for the input and advice, ill +1 everyones rep.

(ps bendo im on oceanic-aman'thul, asia pacific time zone, have been playing for 3 yrs or so now. Have been bored with the game so i thought id pick up an old hobby to fill the time before cata xD If your on my server pst me for details and ill duel you on my priest xD)

Note that old growth will not recover. However, this sort of system recovers almost as fast as it goes bad. If new growth is good, you're golden.

Notice my above post ,My mistake I thought the buckets were higher than the res.Basically whats happening is the hydrotron is to dry and sucking the moisture out of the roots thats why its a good idea to run the dripper 24/7 to keep the medium moist.

 

[FreezerBoy]

Hydroton doesn't absorb, wick or suck. It adsorbs, holding water on it's surface where it's readily available to whatever touches it. Whatever the trouble is, Hydroton stealing the water isn't it.

bull shit Throw a clone rooted in rock wool into a net pot with dry hydrotron and look at the roots hours later,and yes hydrotron does wick to an extent as well as retain some moistire.We have had this pissing match before F/B
I've grown in WF ,I have the 8 pack contoller etc..! thing I do know for a fact if there are are no roots in the bucket they are in the medium wich must remain moist thats why they run 24/7.
Unlike yourself I have sucessfully and unsuccesfully grown in W/F and dealt with some of the probs with these systems.Drip ring and ph probs being the most common.One thing I see with the OP system is a submerged pump running 24/7 is gonna heat the res up wich could pose probs down the road W/F use an air pump so heats not an issue

Let me ask you this growing DWC with water level 2 inces below net pots(air gap) Why is it the fisrt inch or 2 of the hydrtron is moist when it dosnt come in contact with the res


"Hydrotron clay aggregate is an alternitive planting medium for soil,perlite,and stone wool,Popular among hydroponic gardeners the reusable clay pebbles leave plenty of room for air transport and root developmentwhile retaining moisture extremely well,Hydrotron is chemically inert medium with a neautral PH"
Quoted from worms way2010 catalog

 

[jm420]

Adsorb would more describe how a carbon scrubber woud work,not how hydrotron absorbs and retains water

 

[hawaiiOG]

it look like your dealing with a heat problem and if those are clone should of clipped off an inch of your bottom water leaves to help with damping off. first off roots should be in water 24-7 with nutes and plenty of O2 that is what DWC is you have way too much hydroton under your rockwool root should be in water till they get real thick and start to grow down in to your bucket then when you change your water you lower the water level so just the ends are in the water and then your plant will grow even bigger and root will make there way down into deeper water in your bucket.

Yesterday, you couldn't even recognize the system. Today, you're an expert?

Hydroton placed in water does not swell to a larger shape. When squeezed, it does not release water. This is because Hydroton does not absorb. Hydroton adsorbs like flypaper, water sticks to it's surface just as smells and water impurities stick to the surface of carbon.

Note how there is no mention of absorbtion in the quote you provided...

"Hydrotron clay aggregate is an alternitive planting medium for soil,perlite,and stone wool,Popular among hydroponic gardeners the reusable clay pebbles leave plenty of room for air transport and root developmentwhile retaining moisture extremely well,Hydrotron is chemically inert medium with a neautral PH"

Just as we prefer granulated carbon over pellet shaped carbon, we prefer Hydroton to marbles. The rougher irregular surface provides for greater adsorbtion. Water will fill up these holes the same way it fills a glass of water but, the glass doesn't absorb anything and adsorbs poorly just as the marble would. Hydroton will retain but, not absorb.

 

[FreezerBoy]

...that is what DWC is...

This is a Waterfarm, not DWC. Different rules, including double buckets with the upper filled with Hydroton. It's how Waterfarms work.

 

[jm420]

hydrotron to marbles? smoke anotherone .As for mis reading the op posted his diagram showing the buckets on a higher level than res .My mistake again and yes if we were using marbles and not the ones in your head it would be adsorption .do your self a favor and cut a wet clay pepple in half and tell me its adorbtion and not absortion.I did it today for shits and giggles ,and you are wrong sir.Get your facts rite .
As far as dwc and water farms go they are similiar once some roots hit the res ,There is no need for airstones when the drip is running ,similiar to a water fall.
As for double buckets you are wrong again one is a ten inc net pot not a bucket ,Its somthing similiar ,to a 3 inch net pot put in an 18 gallon tub except with a top feed due to the amount of medium the roots have to get through to even reach the res.I'm sure I'll get another infraction for speaking against the great one again.Hijacking and flaming well somtimes you deserve it

Hey guys

i came back after a couple of days and there was significant growth. Leaves still looked down so i created a temperary drip ring until i can get the hydro shop tommorow and buy the mats to make a proper one.

Heres a diagram of the drip ring, as i was drawing it i could see its flaws. I can see how important the drip ring is and how you need it to cover all of the clay ball area.

On one of my plants the roots have dropped out of the bucket and are growing down into the solution which is pretty cool

 

[bendoslendo]

Glad to hear man

Won't be long before you've got some of this. Not mine, got it from the official root porn thread https://www.icmag.com/ic/showthread.php?t=31574

Man that pic you posted is insane!

The thing im fearing is having trouble setting the PH one the roots get that hardcore. Before the roots dropped out of the holes (on the one plant that has) i would lift the top pot off and set the PH in the bottom pots as well as the res. Now im guessing the way i will do it is setting the PH of the water in buckets before pouring it into the system.

The plants look fanstastic and have grown so much since yesterday even. Admitadly one of the plants is going a little better than the other (the one that has its root dropped down).

Tonight i made up a drip ring that has drippers on top and has hose parts that go down under the rockwool (similar to my diagram above, but more of them to make sure the water is hitting the roots underneath on all sides.)

I was really hoping on posting some pics but i left my cable at work, so i will post them tommorow.

You will see in the pics, the plants are approaching thier fourth week of veg and are about 1 foot tall. I have had them on a third strength nutes. Im looking at upping it to two thirds on friday, the roots should be able to handle it.

Peace and thanks for the help

As you can see some of the leaves still look a little droopy but over all viger has improved Ill get some photos of the drip rings as imo they have saved my bacon.

 

[jm420]

good job ,glad to see they made it

 

[bendoslendo]

Tasty lookin bacon!

What are you growing there mage?
