Hello All,
First of all, I don't pretend to know as much as most of you on this board about growing. However, hydrogen peroxide is something I can shed some light on.
First and most important.... we are talking about 35% FOOD GRADE hydrogen peroxide... not what you have under your sink

It has tons of positive attributes. In fact, I put drops of it in distilled water myself and drink it 3 times a day. It's awesome stuff, and I don't get sick... EVER!
Now, honestly, I am just finishing up my first auto grow. I did use hydrogen peroxide in my water. The ladies just love it! Here's what you need to do... First start by making a 3% solution. You do this by mixing 11 ounces of distilled water with 1 ounce of 35% FOOD GRADE hydrogen peroxide (You can get it on Amazon.com). Once that is complete you can add 1-2oz of the 3% solution per 1 gallon of water. This auto grow I used 1.5 oz to be safe, and they are looking great. I also used the straight 3% solution when sprouting the seeds. Give it a try. I think you'll like it. If so, Google hydrogen peroxide therapy as well and see if it might make sense for your lifestyle. it will give you energy, allow you to absorb oxygen better as well as improve your digestion.
Best of luck,
Buddy
