Do NOT use Hydrogen Peroxide

[iloveit]

Hey there FilthyFletch,
I have a few quick questions:

1) Is this standard of H2O2 ok to use in my reservoir http://food-grade-hydrogen-peroxide.co.uk/shop/article_6/Food-Grade-Hydrogen-Peroxide-35%---500ml.html?shop_param=cid=2&aid=6&
Its been almost impossible to find the 35% grade in U.K. now that its readily available I just want to make sure this food grade will be accepted by the cannabis plants in my hydro system.

2) What dose should I use for 35% grade of H2O2? And what dose should I use for 17.5% (I already have a bottle which Ive been using for sterilising).

3) Ive been using Hygrozyme in my SOIL & HYDRO system but its expensive (£37 per litre. OH MA GYAD!). Can I use H2O2 in soil if not what popular product would you recommend keep in mind in the U.K. we dont have access to all the products in the US (assuming you are from the states).

The food grade will work fine at 35% use 2milliliters per gallon. Im not sure on the 17.5 stuff as I have never seen it. On the hygrozyme Im not sure either as I dont use that either.Sorry not much help...ps check ebay it will give you access to everything we have and more

Thanks FF. Ive searched on ebay in the past & although the products are available the shipping from the states can be a bit much ah well I guess Ill have to keep searching.

Another quick question:
Im planning on reusing clay pebbles after washing off the salts & allow it to sit in H2O2 but Im pretty sure that their will be some tiny root matter stuck in/around the pebbles. If the roots arnt completly washed away would it affect my plants?
I use Hygrozyme which breaks down dead roots but will H2O2 do the same or will it simply kill the bacteria?

 

[FilthyFletch]

Reusing hydroton is fine I do it alot. Wash it with a weak hot water and bleach bath stir it alot in buckets and then drain and rinse it several times and drain it some more then clean water rinse it a few times and its fine. Shipping to you isnt o bad if there is something you want from the US let me know and if I can get it I will see how low I can get it shipped to you if it ll help.

h202 works well for me, your the one posting incorrect information

 

[FilthyFletch]

who is posting incorrect information?

 

[morrisgreenberg]

the hygrozyme lable says you can use small amounts of h2o2 with it, they dont specify, i personally use h2o2 for sterilizing, as you already know the h202 goes for the bad bacterias and other organics, too much of it mixed with hzyme will nullify any beneficial aspects of the hzyme, you know you can use the hzyme as you would the h202, you can spray down your clay pellets and let them eat up the old roots, im sure this will take around 5days to get any left over matter, i think your on the right track with what fletch said, let them soak, i like to soak everything in h202 before use, soak till you hear a sizzle, you can use up to 3ML safely per gallon of 35%. hey fletch i didnt forget about you bro, i know you want those pix, but since im moving i have all my electronics packed away and have no idea when im gonna get the to cam, i did stumble upon a thread on icmag where this dude biult the exact same unit

Thanks for your put Ill begin the process tomorrow. Any idea of the dosage for H2O2 17.5% grade?

Thanks FF. Ill clean the pebbles out tomorrow hopefully my neighbours wont get suspicious.

Thanks for offering to help with the postage of products, thats very kind of you. Ill get back to you with a small list of items.

I would say since its basically half strength the 35% then you can double the amounts to make it the same so use double what you would with the 35

 

[morrisgreenberg]

double up, or you can make your own 3% peroxide by mixing 11oz water to 1oz of h2o2 35%, 2 oz for 17%...this is much safer to work with, that shit burns and turns the skin white

 

[iloveit]

So double 6ml per litre for sterilising. So what dosage for using on plants when using the 17.5% grade?

 

[morrisgreenberg]

my bottl of 35% says 1 to 3 ML per gallon, its safe to assume you should double up, so 2-6ML per gallon. i highly recommend you dose it per root system, a well developed root system should be able to handle the higher dosage, young plants shouldnt be given that much yet, just like anything else use gradually cus too much can and will fry your roots

Will epsom kill hygrozyme?

Thanks for your help, Ill begin my use with H2O2 soon & bin that expensive Hygrozyme.

 

[morrisgreenberg]

honestly, the h202 is a constant battle if you should get something in your tank

The dosage is 3.5ml/liter of 17.5%H2o2. You don't need the hygrozyme in hydro and the h202 has the duel benefit of steralization and adding oxygen to your water. If you are using tap water you can add the h2o2 at the same rate and your water is ready to use in 20 mins(compared to waiting 24 hours for the chlorine to evap without the use of h202). I would use the hygrozyme in soil styled medium grows to break down the dead organic matter and keep your growing medium clean.

 

[Earl]

If you keep your nutrient solution below 68ºf
you will never need to use H2o2.

The max amount you should ever use in dwc is 2ml/gl
of 35% H2o2.

Avoid using H2o2 if at all possible.

A cool rez is the best way to avoid the need for H2o2.

[morrisgreenberg]

earl couldnt be more right, keep your lid tight and water cool and you will be perfect

Thanks DR Von for the dosage, should I start with a lower dosage with newly rooted clones & work up to 3.5ml per L?

To my understanding H2O2 will degrade to ONLY H2O if left out too long, assuming this is true should I change my reservoir more often than once a week? keep in mind that within a week I top up my res with tap water due to evaporation & transpiration.

Ive been wanting to know how to use water straight from the tap without waiting 24hrs so thank again.
