H2O2 in coco - Page 3 - Growing in Coco Coir - International Cannagraphic Magazine Forums

Yeah, if you add enough H2O2, the chlorine smell dissipates. I'm sure there's still trace amounts but not anywhere near enough to piss your plants off.

I doubt the problems are chlorine unless it's a hella lot. What symptoms are the plants showing?

I use it weekly during the summer, when relative humidity is high. In the past I've had some issues with algae in my coco and the peroxide kills it. It also combats fungus gnats.
I also use dilute peroxide when cloning. It adds essential oxygen which accelerates root development, and keeps pathogens like mold at bay.
I think the argument about micro-organisms has little merit when growing in coco with chemical nutes like Canna.

Yeah dude, works great at killing off aerobic activity in the res too... Sick of replacing air stones? Use H2O2...

Hi fvk

They lost colour, greenness, but no other great symptoms IIRC. I changed the regime slightly so the water aired for longer, added more N/P pH- as opposed to P pH- [GHE's buffered N&P pH- not Nutriculture's purely Phosphoric] ... bringing pH down from 6.2 to 5.8....and added slightly more Canna Coco A+B [up to 2ml/L] .. things got better, so my friends switched into flowering & all recovered well enough.

As I changed several things it is hard to know what part fixed it, it was all done on a best guess / good practice basis, in a friends garden I see 1x a week at most.

Next time I will get them to try a H2O2 experiment on part of the crop/plants to see if it helps.

Glad to hear you guys got things under control. I think lowering your ph was a good idea for one and it may be that you needed to increase the number of feedings and spread out the original EC strength among them. Know what I mean? Might have been getting too thirsty and not fed enough. Like I said, it'd take a hella lot of chlorine to piss them off.

BUMP

I think wev'e been fooled,

h202 in coco might be the next best thing

every feed, before you put in the nutes, I think 2 or 3 ml/gl with a 20 day flush, no bennies

the question is how much do I add when I flush or do I even?

mean mr.mustard · 01-07-2018, 02:18 PM

I use it at 8 ml per gallon in my nute solution and clone water.

No more root rot.

Recently i had some fungus gnats and attempted to kill them by flushing the coco with straight 3%, followed by normal watering. While it definitely wiped out alot of the gnats, the plants have been slowly looking worse and worse each day. Leaves yellowing and curling up at the ends.

Do you think that by not cutting the 3% solution i essentially have burned the plants out? At this point it is hard to tell if they will recover. Coupled with this the humidity has been real low (15-20%) so i was considering that as the cause but leaning towards the H2O2 because the plants seems fine in low RH before i used it. It was drug store product.

Mosquito dunk should be all you need for gnats.

I haven't used it straight I would think that would likely harm a plant.

RumblefishTwist · 01-07-2018, 09:04 PM

Yes will use other gnat remedies in the future, no doubt.
