Rootrot

[dogmeat]

A few 2 liters of cheap soda! Empty (or drink) and fill with water and freeze. Swap em every 12 hours and root rot is a memory.

Yea, Ive been thinking about that as well. Seems like a good idea....

 

[dogmeat]

here's what I'm dealing with.......

ouch bud. that hurts to look at. How many days sick?

 

[dogmeat]

Do you know how monotonous this gets.... I had rez temps in the 80's and was using anything I could find.. from soda to ketchup bottles.... on the hour every hour they would be melted and same warm temp as the rez.... put a fan in/on your rez, or get a chiller.... don't think you'll make it with rez temps in the 80's...odds are lots of algae and pyth...... YUCK..... also I wouldn't waste alot of money on additives to try and resolve your current situation... just flush it out and try and let the plants finish... a little h2o2 is cheap so that'll do.... next run you HAVE to keep the light out and the temps down.....

I'll grab some pics of current root rot issues, and
show ya what I did....

6 Plant DWC.... all in 10 gal rubbermaid.....

1-4 finished early and were harvested.... 5-6 left...

This is the rot... plant 5 of 6 had BAD rot from being left unattended, (mainly complacency on my part) was removed....


Plant 6's now mutilated root system... siamese surgery if you will....



Plant 6 showed some stress but pulled through the rot

Excellent information. This thread could be helpful for others as well. The holes on the new hydro tables and rex i covered up. So everything has no possable light in there. I need to get a temp thing for my rez as well.

Glad your were able to battle the rot, that stuff can be vicious to get rid of. Try to clean your setups Really well to make sure it never comes back.I like to use a 10% diluted solution of white vinegar to disenfect then i will use full strength h2o to kill any residual bacteria. oh and make sure to rinse them out real good. The vinegar is organic and will breakdown, so is sm-90. I would not advise to use harsh chemicals such as ammonia etc...plastic is porous and will absorb harmful chemicals. Wish you better luck on the next one my friend.

my plant only shows signs for a few days and then die. I've lost about 100 plants. I feel like it's the first time I've ever grown. I've dealt with every problem out there, and I would trade spider mites to get rid of this.

Thankfully, the other half of the room is doing good.

i have gotten rot especially in reveging plants but shit not ever like that.

 

[dogmeat]

I still am having problems too. I notice that if I put my hands on the rockwhol, its damp wet. Should i let this dry out before next watering?

Also, I lost another one. I see what they say by ramm horn, then the play shrivles up and dies. It fuckin sucks.

Hey, I didn't want to hijack your thread, so I started my own... hopefully we can all learn how to control this crap together.

For active root rot it seems the combination of Hygrozyme and SM-90 is the cure. Hygrozyme alone as a preventative and to support optimum root health. Obviously what people have already said...too high water/root temps and light exposure. Adequate aeration in something like DWC is critical! Someone told me you gotta try and shoot for 50% water and 50% air (from pump) by volume. Next time I see him I'll double check that info. This volume of air is WAY over the top for what you need to maintain 4 PPM DO levels though. Some research I read online from New Zealand indicated pythium has a much harder time getting established and growing when dissolved oxygen levels are over 4 PPM...which is actually pretty easy to achieve.

A new product I just picked up and am going to experiment with is House and Gardens Van de Zwaan Roots Accelerator. Uber expensive at like $110 for 12 oz with use of 1 oz per 25 gallons. Labels says use first two weeks but the dude that told me about it said use throughout the entire growth cycle. He said no ifs, ands or buts you get white healthy roots no matter what else is going on. He's convinced it can be used as a replacement to the Hygrozyme/SM-90 combo. The addition of Roots Accelerator to his DWC setup is producing phenomenal results. I'm in rockwool slabs now but will get a small DWC setup going to try out.

hydroguard! GH.

I've heard some people experience major pH fluctuation issues using Hydroguard...but that's just what they say.

I still feel that pre-emptive actions are your best chances at battling rot... I find that if I am very nit-picky ,if you will, temp issues and light/algae, are not an issue....

Eh, I just got back from vacation. My lights were out. Dont know how long. Now my 400W wont fire...after being plugged in for 12 hours, still no fire.

I have it plugged into one of those screw in recepticles for light sockets. It rattled lose and shut all the power down. Musta shorted the light out too. Id hope not.

 

[sonoma]

yikes, unplug for 20 minutes and try again. some ballast need to cool down before they restart, so if the power was only off for a minute or two, it wouldn't have cooled down. good luck!

 

[dogmeat]

No go. Its been unplugged for two days, plugged it back in and its not comming on. The funny thing is, my 1000W is on the same power adaptor, (i know this is not good, will be rerunning wire soon), and it works fine. So obviously somthing pooched that light out. Good thing it was only 40$

how much water would you estimate that to displace in say a 10 gallon dwc??

root rot is a bitch. I got it pretty bad in my first DWC grow. My advice to you is if you get it bad to cut clones and kill the plants, clean your system really good and start over again. Hygrozyme is excellent for prevention, but you'll still need to watch those temps and light leaks. frozen water in 2 liter botttles can definitely keep temps in check but can be tedious changing the bottle because they melt quick.

With root rot if you get to the point where roots get dark and slimey and give off a rotting smell (smells like soil), then usually it's too late. not worth the time and effort tyring to save the hplants, just kill em and start all over.

I also have never had a problem with root rot when plants are in individual buckets. It's always the ones that share a rubbermaid tub.

 

[dogmeat]

Mine were in individual buckets.

Im not sure of this. A 10 gallon bucket, you are only going to beable to put one or two down...

my ph never swings wildly with hydroguard
