hydrogen peroxide sensitive to light?
    #4015280 - 04/05/05 01:18 AM (13 years, 1 month ago)

so, yuckmouth told me that hydrogen peroxide breaks down in sunlight.
can't remember hearing this, but it comes in an opaque bottle...?

anyone verify this?

my thought is that if it is, then anyone who keeps a spraybottle of solution would need to make sure it is not transparent/lucent.
:strokebeard:

oops!

Yes, it does break down in sunlight and that is why it comes in the opaque bottle.

Stop experimenting half way through your first grow. Grow it to maturity, watch it, learn from it. Do this a few times then experiment with different ideas and figure out what works best for you.

I wonder how long it takes light to completly break down the peroxide in a spray bottle 1/10 solution.

Depends on how much light, what kind of light, how opaque the bottle is, ect...a few hours, up to a couple days.

Actually, if your misting regularily, it doesn't matter.
Reason... once the H2O2 has been added to your misting water, it's job is done... it has successfully reduced any contams (you were using distilled water, right?)
After the initial cleasing effect of the H2O2. You are best to have the solution in a light proof bottle to try and retain any minute H2O2 properties, or in a clear bottle subjected to light with a high ultraviolet content to continue the process.
So!!!! Don't worry about it :smile:
