Aluminum sulfate

I’ve not planted anything yet because my soil ph is 8.2. I was thinking about using aluminum sulfate to lower the ph. What are your thoughts

Welcome to ILGM forum. What kind of soil are you talking about. If it’s that high why not change soil.

Welcome to the forum. I agree. I would go with a soil that is properly buffered for cannabis.

@Cookston, how are you determining your soil ph? Hopefully not with one of those 3 in 1 soil meters.
