Safe bug solution?

As I mentioned earlier in this thread...all you need is 35% h2o2 to kill all bugs. 30-60+ mls/lt. kills (burns) bugs and eggs, and can be used well into flower. Spray 2x/week for a couple of weeks to make sure you get any strays. Plants luv it, and it kills PM too. It can also be used as soil drench for soilborn pests (not reccy for organics as it will kill beneficials as well).
peroxide is not good for hydro like some would suggest as it kills the good culture as well.
Its a last ditch attempt at helping your harvest finish and usually people try using it to stave off pythium as their system/environment is not up to snuff to stop the pathogen from occurring..like PowerMildew as well.. its around all the time but needs the right (wrong) conditions to set up on your plant.

all these things are designed to save a crop....not to be used all the time as maintenance.
Growing clean is key,

Are you saying 35% H202 65% Water in a spray bottle? Or 30-60ml per liter H202?

Killing good culture is not an issue if your running 'sterile' as most do in hydroponics.

There is no 35% peroxide in hydro stores in Canada any more, its 29%. You can get 35% food grade 55gal barrels from Univar BUT you need to apply for a distributor/reseller exemption (is good for 5 years) and if you sell it you have to take personal info of the buyer. The problem with the 35% is the cost vs the 29% even if you were to water it down.

You have to apply for an exemption to sell it which reminds me I need to renew it as 5 years is almost up and you can get away with selling small quantities. I can also sell potassium nitrate in smaller quantities but am suppose to take peoples info when I sell it. I buy 55gal barrels of every few months. When I talked to Univar only difference between Food grade and Tech grade is they dilute the 35% food grade down to 29% and because its not diluted/packaged in a Food Grade facility it's not legally considered food grade anymore. So unless that stuff is packaged in certified food grade facility its not food grade even if it started as one according to Univar..

Just talked to Univar on how they make theirs but have to wait till their tech guys calls me and waiting to get price on their Food Grade. Going by the price they quoted me 5 years ago its about a $1 more per 1L then Tech grade. That's not bad , looks like I'll order a 55gal Food Grade next time, just have to read up on how long the shelf life is. Didn't know about the stabilizers in tech grade stuff..

So it's basically the same stuff just watered down a bit? At 29% that should still be strong enough, just make a slightly stronger mix ratio. Oxidate (Storox) is like 27% and it works fine as well.

Going back to an email from 4 years ago the sales person stated they dilute the 35% Food grade down to 29% but will have to reconfirm when the tech guy calls back where its food grade they dilute or stuff to stabilizers in it. Either way pending some crazy price increase I'll go with the food grade this time.

29% is the percentage as the gov doesn't want terrerist aka freedom fighters to clean things with 35% even though they could easily turn 29% into 35% if they wanted to.
