coco and hydrogen peroxide? application & ratio

John goodman · Aug 29, 2008

Hi all,
what would be the correct ratio to treat over-watered coco with damaged to young plants? and how would i apply this ... can i then use it thru the whole grow cycle? how is this applied to the res if so ?

Any help input greatly appreciated

I have used in my canna coco medium, rhitztonic and canna coco a+b

cant really answer your question, so my bad on that. but i would figure you just let that bitch dry out. i mean do your pots have proper drainage holes? i dont think you would need to use it thought the entire as coco has great aerating properties

Don't use it.
It will kill all of the trichoderma in the Canna coco.
If the plants are over watered, water them less.
Easy fix!

well i had them in 1 pint plastic cups before i transplant to my 6.5 ltr sq pots...its never happen to me before and over time the holes in the bottom of the pint cups have sealed/blocked up... I was away for 3 days came back the water was still in them and plants droopy over the next few days the plant has gone pale etc ... I think the plants have been damaged due to this... I ve since repotted in the hope the new medium (recycled) will act as a sponge...I also squeeze and put new holes in the pint cups. I have a few with new roots with lock and the ones in the big pots think need a flush thru ?? then hit em with nutrients after that has dried up ...

thanks for the prompt response ... I hope the extra detail will help

Although I agree with the best course of action in this case would be to let the medium dry out, I have to disagree that using H2o2 will kill all the trichoderma present in the coco.

Actually, in this waterlogged state, there may be an overabundance of trichoderma helping to cause health issues.
And even if you were to kill out all the trichoderma in the medium, it would be no big deal. It would not show up as a problem with the plant in any way.
Trichoderma is only a fungal control agent, and as a result is a good thing for the root systems. But, it is not a necessary add.

Trichodermas are not completely understood by the horticultural world, and things are still being learned about how to actually use trichoderma as a proper control agent. I highly doubt that Canna has any one up information that the rest of the scientific community does about the use of thrichoderma fungi.

If you have cannazym let those pots dry out and add some cannazym in the next watering. It'll do wonders! Do you have any perlite mixed with your coco? I think you definitely should allows for alot more aeration and the medium drys out far quicker.

HD thanks for that ..Ive read many of your comments on this trying to research this

very informative....I've got 17% HP what ratio should i use it at ??

Thanks for your input GDS but ive never had any issue with straight coco and think what as caused my issue is the overwatering in 1 pint cups and the knock on effect has been suffocation of the new root system block the nutrients...I have got some new growth but stunted and yellow ....looks like cal/mag at the moment ...Im hoping i can hit em with the HP and then give em a nice balance nutrient with some Cal-Sea-Feed to hopefully get em back on track

well thats the plan....please let me know what i should be using per ltr of hydrogen peroxide

hoosierdaddy · Aug 30, 2008

Again, I also think your best course of action is to let the medium dry out first.

I like to use H2o2 at a rate of 30ml 3% per gal.
That equates to just at 8ml per lt. of 3%
I think that equates to about 1.4ml per lt of 17%....but you need to check my math.
I would never use that strong of solution just for the fact that you can screw up total grow so easily with it. It would be hard to screw up things from a booboo with 3% from the grocery store.

dongle69 · Aug 30, 2008

Hydrogen peroxide will also kill any mycorrazae and beneficial nematodes.
You should avoid the stuff in coco or soil unless as a last resort.
In your case, I don't think it is necessary.

ok guys thanks...ive just been to the grow and i thought i would pour 2ltrs of ec1.0 ph 5.8 thru 1 pot and check the run off...........ARGHHHHHHHHH ec3.6 ph 5.1 MENTAL

I had flushed the medium from last crop for 2 wks with just ph'ed water ???? the medium had completly dried out before i used it again.....lesson learnt,big styleee but would of thought it would of been OK??...i do think it was still overwatering from the begining and me just putting them straight in to this recycled medium as not helped matters!! I JUST DONT KNOW!!!!

so im goner flush with ph'ed water and then let dry out...get a good base to begin again

...correct me if im wrong:- if the pots are 6.5ltrs and i use a 13 ltrs to flush each pot that should be sufficient????..I'll keep you posted

thanks for your help

Flush with ph'd water and a low ec like .6 .
It is not good to flush coco with plain water (unless you are flushing to finish).
It throws off the balance big time.
Keep flushing until runoff is good.
As much as it takes.
Like you said, let it dry first.

DC3 · Aug 31, 2008

hey guys... I read somewhere that if you need to use H2O2 you should leave it in sunlight for awhile (say 5mins) and that negates, to some extent, it's kill power on the good things.

young plants take a while to come back to full health so be patient especialy when transplanted into bigger pots. They will come back strong as so don"t worry.

dongle I've flushed with straight water from my shower unit...its now ec0.8-1.0 with a ph 6.2-6.5 the highest.

what would you suggest for me to achieve equilibrium within my media? I was going to just hit em with a well balance nutrient at correct ph......any ideas on what sort time scale for normal growth to commence

thanks again

dongle69 · Sep 1, 2008

Hard to say how fast they will get better without pics...
Plants can usually bounce back quicker in coco.
You are right, hit em with a well balance nutrient at correct ph.

ive been adding up to 12ml/Gal of 3% H2O2 every 4-7 days in my recirculating coco drip system. It definitely helps keep the pump filter clean, and im pretty sure it cured my fungus gnat problem (kill the gnat larva food, break the cycle).

hey goodman, hopes you got it sorted bruva :smoke:

John goodman · Sep 4, 2008

thanks it seems to be on the mend ...what a plonker!!! I know but first time for everything ..i will know next time... ive also been blessed from a good friend some blue moonshine dj shorts which is an exceptional smoke and yield

Ive also been panicking and got a few others on stand by..I will get some pics up... shame i haven't got any of before the mend...the plants have now normal growth and alight green indicating just a light feed required now and coco is drying out nicely now... not a mad burnt strange yellowing randomly on the leafs now ..im pleased

thank you all for your help and peeps behind the scenes
