I have seen posts regarding using Hydrogen Peroxide to get rid of mold, what would be the ratio be to deal with this issue (I purchased 3% HP).
No idea but im watching for my own knowledge

I have the bags elevated as you see specifically to provide airflow all around the bag.
How often are you watering? I know being outside in the elements u want to keep her hydrated. But dont feed the fungi

Because of the heat, I give them 2.5 solo cups water each. 1 gallon of water for 4 plants, usually split evenly morning and evening on watering day which is every day. 2 cups results in runoff. I am wondering if it is because of all the rain we were getting.
I water daily because sticking my finger in the dirt (about 3 inches) reveals perfect soil conditions with my watering schedule, when it rains I forego watering.
Sounds good… give it a bit. The pros be with u in a bit. Im like the elevator music when ur on hold. Here to keep ur mind at ease n u from jumpin off the roof

So after doing research, it is algae and not mold/fungi.
Does it make a difference in treatment method?
Algae looks moldy to me

Right, that’s why I’m kinda worried.I dont want it touching my roots.
Ive heard its not… moldy persae as in a danger. Its more of competition for nutrients
I use 1 bottle of 3% hydrogen peroxide 32oz to
1 gallon of good ph’d water …
It sounds like you might be overwatering… I know it’s hot out side , but unless you start using more perlite mixed in with your soil , you will always be walking a fine line for overwatering…
When I used to grow in soil it took me a long time to figure out watering practices with different pots and size of pots and what kind of pots… plastic or fabric… that sort of thing…

If you just want to eliminate the algae or mold on the outside of the bag, just spray straight 3% on the outside of the bag. It should be gone in a couple of minutes.

@peachfuzz, I have a 50% perlite to soil mix. Don’t know how much more perlite I could have mixed in. 2 solo cups of water already result in run off at each watering. Soil is dry 3 inches down when I water so I don’t see how I can be overwatering.

Just putting it out there… usually when you see algae build up … its do to too much moisture and always wet conditions… 
It’s easy to overwater when it feels so hot outside… all’s I’m sayin…
Good luck my fellow cultivator…
