H2O2 Question

i just bought some 29% H2O2. i was wondering do i add it to my res before adding the nutes to feed? if so how long before? or can i add it after i mix my nutes?

...most growers use the 3%, you might want to go easy w/ that 29%. I put my h202 in every other day no special order of when to use it, use it as you need it. Good luck.

I've just fed mine from a bottle of 35% Hp at 1ml per gallon.
I put it in just before the nutes and PH'ing.
Time will tell if I've done anything wrong.

anything bad happen yet?

Nope. I've done the same thing again since that post and everything is fine.

same here everything is great. ive read to add it a few min before your nutes because its an oxidizer and will mess with your nutes. i also e-mailed the company and they said the same thing.

I use 29% at a rate of 5ml per gallon of res water. and after 3 or 4 days i add more because it evaporates fast. 3% is worthless

I use 29% H202 on a daily basis. 14ML dailey per 25 res gallons. Works great. I usually mix it with one gallon of water and pour it in just after lights out. I usually wait 5 or 6 hours at least after putting in any nutes. Increases oxygen in res, and keeps it free of root rot at the same time. Done it for the last 2 years. Just don't add it to the res without mixing it with a gal of water first.

Are you using organic Nutes??? If so it will kill benifical bacteria.

Chlorine works just as well if not better. If your going the sterile route that is. If not and u want to use organic nutes/additives go with a enzyme product like Hygrozyme

I have a question about the 29% solution. When you dilute it with water, at 3ml per 4 liters of water, does that then make it 3%? I'm trying to figure out how much to use daily.
