I am sure there will be varying opinions but with a little discussion, I would think a good all around ball park range can be had.

Also, in a container, pH is much less important than it is in the ground.

It's also easier to simply modify your water's pH than to try and maintain a specific
soil pH - which is always fluctuating depending on moisture and nutrients, et cetera.

Add a little white vinegar to water to bring pH down.

I just got my soil tested, and its pH is 7.6, which is a little on the alkaline side, which is no surprise since limestone is my bedrock here.

This is above the pH range everyone says peppers should be at, but I still get bumper crops of peppers. Also, peppers grow wild around here (chile pequins, the wild version of C. annum), so this is pretty much their natural habitat.

Almost makes me think that pH is not that big of a deal, at least not for peppers.

Here's something that Al (Tapla) wrote on the subject. I've linked the Thread below.

"Why would containers need different pH requirements than in the ground."

First, they don't NEED a different media pH, which is much less important in container culture than it is in the garden. I've puzzled over how to answer the question in a way that's easy to understand, because it's a complicated question. First, pH affects mostly the solubility of essential micro-nutrients and other nonessential elements that can become toxic, once certain pH levels are reached.

Basically, in mineral (garden) soils, the micro-nutrients are already IN the soil, and the ideal pH is a happy medium where all the elements are in a favorable part of their availability range. Too much deviation either upward or downward in the pH level can have a significant impact on availability and toxicities.

In container media, the organic components contain only very small amounts of micro-nutrients, locked securely in the hydrocarbon chains of the medium. So, raising or lowering the pH of the medium or the soil solution has little impact on the availability of these nutrients.

If you point to a pH induced Fe deficiency and say Hey, look here - a pH induced deficiency", I'll point to the fact that technically it's not a function of the pH, but of the presence of high concentrations of Ca, Mg, Na, or bicarbonates, with the increase in pH being only the symptom.

If you could use a medium that is devoid of potential toxicities, and has all the essential nutrients in the right ratio, you can grow most plants very well (in container media) at pH ranges from 3.0 to about 8.5.
