View Full Version : Best Way to Curb Root Rot

I am almost to week 4 in veg, almost ready to start flower, and I have what I think is the beginnings of rot rot. There is about 1/2"-3/4" of water that doesn't drain out of my bins and two of my seven plants have roots that have grown to the point that they are long enough to just sit in it all day. The roots look slimy and brown but they don't stink and if I wipe them, the brown sludge comes off and the roots are still white. I use organic nutrients so that could account for some of the brown color, but I still fear the worst. I tried tilting the bins toward the drain to get it to empty completely, but then when it floods it causes the bins to overflow because the drain can't keep up and it makes a huge mess.
I am heading to the hydro store today to pick up something to try and curb it before it gets worse. I have heard about Super Thrive and Hygrozyme, but I wanted to know what the pros recommend. I was also going to put H2O2 in the water that rests in the bins whenever I can. Any help is greatly appreciated!

Bumping this...
I need an answer in the next 4 hours! Can anyone help me out here? I would research for myself but I am at work and can't look at cannabis related things on the computer and I am posting this from my cell phone.
Help a brotha out!

Hey Deja....I know of two things.....the hydrogen peroxide you are using or the zyme products....(I use cannazyme myself). Make sure you are using enough (store bought) H202 for your purposes.....I use 2 teaspoons per gallon EVERY OTHER DAY. If you go with one of the zyme products then you cannot use peroxide......it's one or the other.
Personally....if you have the cash, go for a zyme product. If not stick with your H202 and just try to be very consistent with using it. ;)
I'm running a DWC bubbler with a wick and my roots sit in aerated solution all day. I use Dutch Master Zone as an antifungal/root conditioner and it seems to work well for me. Only 1ml/gal is needed.

I got some H2O2 at the suggestion from the guy at the hydro store and I also picked up some SuperThrive. I put 50 ml of H2O2 and one tbsp of SuperThrive in my 15 gallon res. Both had very unclear and indirect application directions, so hopefully I don't cause my plants any problems. Thanks for all the help!

Weedhound, how big is your res?

Dejayou - You only want one drop of Superthrive per gallon of water.

Well, uhhh whoops? 1 drop is about 1 mL right? So I don't think 1 tbsp is too far from 15 mL. I was pretty sure I was close to what the box said. It will only be in there for 3 more days since I am going to change the res on Friday anways to start flowering. Do you think its that big of a deal?
Also, I don't need to know the size of your res Weedhound. I was stoned and thought that was info I needed. :D
Also, when you say 2 tsp per gallon, is that for 35% H2O2? Because that's what I have.

Well, if it makes you feel better, sure, you're close. :D
... but I'd buy an eye dropper just to be sure. :thumbsup:
If the plants aren't suffering, then it's no big deal. I'm not trying to be a smart-ass; I just don't know what too much Superthrive will do.

Yeah I hear ya. Hopefully, if I did put in more than I should have, it just means they will thrive extra super! Hahaha, I will be sure to keep a close eye on them.
Do you know if 2 tsp of 35% H202 is good to fight off root rot?
Oh, and I was wondering how often to add the SuperThrive. The packaging is such a jumbled mess that I can't find it on there!

I always use Superthrive (along with Clonex) for the clones, always with B1 for transplanting and whenever the spirits move me for growing plants. Superthrive is as much voodoo as it is science ...but I see no advantage to pissing off the grow gods so I use it anyway.
I don't know about the H2O2 - maybe if Weedhound drags her butt out of bed she'll tell you. :D

Ok....its out......sort of....LOL. :D The peroxide I'm talking about is your regular store bought....3%.....not the super stuff at 35%.....that may wipe you out right there so NO on a couple of tablespoons of 35%. I just the other day bought some of that super strength H202 myself and haven't figured out the dosages yet so cannot offer your amounts for that.....only the 3%. My usual dosing for that is 2 tsp (10ml) per gallon but I'm sure there is some room to work with using the store bought stuff.
Ok.....ummm.....1 ml is not really the same as one drop.....watch them carefully and if they seem to turn a darker green change the rez asap.....you may not have a problem if your plants are old enough. I killed off some brand new seedlings with 1ml/st per gal but my older plants (about 4 weeks old) did fine at that strength so just keep an eye.
I'm going back to bed.....:S2:

1 drop is a fraction of a mL.
Hang on let me go check with a scale and a similarly viscous liquid- I'm at the lab atm.
Okay using a detergent of similar viscosity to superthrive, and a dropper with an opening similar to an eyedropper you'd have around the house, I got 45 drops = 1mL measured in a vial graduated in 0.5mL increments.

Well piss, looks like ill be changing the res when I get off work. Ill have to do some math and vigure out how much 35% to use. Thanks for all the help guys and gals.

Stinky don't get me started with that kind of thing.....how many drops in .02ml? Or .003ml? I could go on forever with that kind of thing. :D That is EXACTLY The kind of mindless info I love. :thumbsup:
The stuff I killed in ST were BRAND NEW-just-popped-out-babies but older plants may do ok....mine did at 1ml/gal for several weeks in addition to reg nutes.....Stinkster knows more about this kind of thing than I do. I will bow to her word. ;)

you all know how much I love Superthrive ... NOT ... ( hoo-doo medicine-show crap cure-all ) ... one drop per gallon for cloning purposes, and I wouldn't swear that it helps with that ... but, I HAVE killed seedlings with it :wtf: ... as my 2nd-generation nursery owner (botany degree) says " I sell LOTS of Superthrive, makes me feel like P.T. Barnum, 'sucker born every minute'... :jointsmile:

... Yet, still, you use it. As a recovering catholic, I truly believe it is fear of angering the grow gods that compells us to use it. :D
The farm supply store near my home sells Superthrive by the gallon. I think the strawberry farmers use it. (It's actually quite reasonably priced by the gallon - somewhere around $40-$60.)
... but what the hell would one do with a gallon of Superthrive? :wtf:

My plants are 4 weeks old tomorrow, and they are al very healthy and vigorous; to change or not to change? I am still on my way home so I haven't looked at them yet, but what do you guys (and gals) think?

I personally would check the ph and look at them and see what they look like. If the ph has done a jump up or risen quickly when it is usually stable that will make me think about fertburn a bit. If things look ok I'd just keep an eye on the ph and the color of the leaves (too much nitrogen will turn the leaves a dark green color...REALLY dark green ;))

Well the pH was at 5.8 which is right where I left it this morning and the leaves don't look abnormal so I'm gonna forgo the res change, especially since its a pain in the ass to haul 5 gallon buckets back and forth across my basement to do so and I will be changing it on Friday when I switch to flowering.
I really appreciate all your guys' help! Thanks to you, my plants are healthy and thriving and will hopefully produce an impressive yield!
