Hydrogen Peroxide for Aphids

Can someone please tell me the ratio of hydrogen peroxide to distilled water to spray for aphids. Every article I read says something different. Some say 1 part hp 2 parts water some say mix equal amounts and some say add one tablespoon of 3% hydrogen peroxide per eight oz (one cup) of distilled water. I’ve already lost 3 of my 5 girls and I don’t want to loose the 2 I have left. Please help:)

I use 4 tablespoons of 3% per pint of water. I agree, you'll get 100 different answers on this one.
How often do you spray the plants in flower? I sprayed this morning early and I don’t want to kill them by spraying to soon or to often.

I spray for them once, see the results and go from there. Stay on top of them and remain vigilant. Watch for ants, they love and 'farm' aphids. Look-up the life cycle of aphids and you'll better understand. Good luck, I hate those buggers!
Can I spray every morning? Or would that be to much?

Yep, absolutely, go for it! Roses in the area can be a big attractor, they love those, too.
The lady next door has roses all over her yard :sad: I found ants today so I’m going to do a cinnamon treatment on the soil tomorrow and see if that helps. Have you ever heard of this?

With water I spray them every day as needed, but be careful around any buds, you don't want them soaked as you'll create other problems. As far as H2O2, just be very careful and make sure it's very dilute and I wouldn't do it every day, I'd alternate or something. H2O2 in very dilute amounts can be beneficial but too much and you can ruin everything.

Oh, that's like a giant neon sign that says "Eat here!" You'll need to be extra vigilant. That's exactly why I moved my grow indoors, the neighbor's roses were too much to deal with. They'd decimate her roses and my plants in no time at all. There are various 'treatments' out there, but I've not tried them. I really wish you luck with this one, let us know how it all turns-out.

I used 1/2 a cup in 2 leters of water. So it turns out to a tbs. to each cup. And do you mean the buds will get mold if soaked? Because I didn’t soak them but there wet. I have a fan outside blowing extra air so the buds didn’t stay wet for long.

My neighbor has 2 lovely rose gardens on her property with about 20 mature oak trees full of black ants. The ants are ever-present, the aphids find her roses, the ants farm the aphids. I don't know how she puts with it. But, it's really lovely.

Well, it's really lovely twice I should say. First the roses are in full bloom and awesome. Then, the aphids destroy them to the point they don't look like they'll survive, in-spite of her best efforts to control them. Then, later in season the roses start to veg, then bloom again and look spectacular and usually the 2nd bloom late in season the aphids don't seem as interested, probably due to the temperature, but I don't know. Anyway, that's off topic and you have some pests to destroy. Happy hunting.

OK, this got me to thinking and I'm curious what some of our more experienced growers would do in a situation like this with aphids on an outdoor grow (purely hypothetical): you have nice plants nearing the finish line, fat colas and you've managed to prevent any visible damage to the buds themselves. However, the aphid damage to the leaves is so extensive that there is essentially few if anything left of the fans. Pistils are 50% brown and receded, trichs are looking cloudy with a random amber one here and there. In other words, you're getting a bit close, but the leaves are essentially wiped-out. Would pushing the otherwise healthy-looking plant further help, hinder or just be a wasted effort? I could see just this scenario happening when I look my neighbors' roses next door. Thus, why I moved indoors.

That happened to two of my plants. Fat sticky stinky buds and then I figured out I had aphids and with in days my buds had become loose not sticky and no stink at all. Most of the trichs where cloudy with a few amber just like you said and I wish I would have harvested a little early and got a energetic buzz than loose my plants like I did and get no buzz at all. Lol
I have the two left and that’s why I’m trying everything to save them. When I just went out to look I ended up looking in between the buds on the stems and oh my god I killed a bunch.I don’t know how I’m supposed to get those suckers with the spray because there in between the buds that are stacked together. I HATE THESE THINGS!!!!
