Soilless PH window specific peat/coco/perlite mix
Ok I need the nail in the coffin guys. I’m using Fafard Root Factory RF C8. Picture shows ingredients. What is my ideal PH window for this type of mix? I’m also about to transplant. I normally just fill a pot, sprinkle Dynomyco, drop plant, fill in and water. Is this correct?

Hope this is ok to post, looking at having a go at hydro on my next grow mainly to cut down on maintenance. What are people’s thoughts on the two systems one is stranded bubble the other one has a dripper I’m guessing will help at beginning of the grow. Thoughts please 🤙

Pot shapes and sizes?
Do you think pot shape, not size..produces more uniform plants and do you think pot shape makes a difference in what weight she can bear at the end of flower?

False reading or Hi PH?
Is 20% humus lombrico mixed in my substrate giving a false ‘hi’ ph reading? Or is it truly over the max reading? I got one reading of 7 only at the exact second I took the picture, so I made a video. My water is high in calcium, I recently switched to distilled.

10g pots a good idea?
I am using 10 gallon pots on this grow with a mix of soils including some from the chicken coop (aged). As a new grower I see a lot of advice to go smaller. To me larger systems are more stable, am I off?

New grower. Swapping out my promix for soil. I wanted to make a mix of Happy Frog, Ocean Forest and perlite. My Happy Frog soil received via Amazon is full of roaches! Dumb question but is this trash now? How in the world do I return an open bag of soil to AMZ?!

Manure in outdoor pots.
How much manure should I mix into my pro-mix. I have a pile of seasoned manure from last year and want to use it in my outdoor pots. I want to mix in some Gaia Green bloom into it also. Thinking of using 10 gallon fabric pots. My photo seedings just popped out of pure pro-mix.
