ProMix HP question
So, I was at Home Depot and noticed they started carrying ProMix HP. HAD to pick some up just because I've heard such great things about it. KInd of pricy though -- 25 bucks for a 2.2 c.f. compressed bale!
Anyhow, I don't get it. It's a container mix but has mychorrizae in it. Most container people will tell you that pots aren't a good place to build a microherd. (Though, I think my large oak barrels do an ok job. I find worms in it, so they must like it,, It's a mix of potting mix, compost, a bit of peat, and perlite. I also use organic meals in them).
But here's some questions regarding the ProMix HP
So why the fungi in a container medium if not a hospitable place for them?
Do I use it straight up?
Do I add some compost?
Should I mix it in some 5-1-1? At what ratio?
Organic ferts or conventional? Wouldn't the conventional be bad for the mychorrizae?
Any need for lime or gypsum? My water is at 8.1 ph
What's the ph of it straight up?
If I was to use straight up, should I add a bit more perlite?
Here's one that really gets me --- Like I said, heard great things about it, but it consists of like 75% sphagnum. Not the best word in the world when hearing some of you talk about container mixes, especially at that ratio.
See what you guys/gals can do in answering some of my questions. I want feedback! ;)
