I guess I will be driving an hr or 2 to the hyrdo store unless Calmag is available at Walmart or Lowes or a garden nursery, as checking run-off will be likely impossible.

The higher pH waterings that I will need to do in the future (but not now, why?) with the Calmag, what exactly is the higher pH I am looking for, or does Calmag just automatically buffer the pH at the appropriate level?

Thanks so much Stinky, as usual ; ) Hopefully the Calmag box will tell me how much to mix in the water.
melodious fellow Reviewed by melodious fellow on . outdoor in containers, I think I heard I need calcium? It feels quite foolish to be asking this question. My first time growing in containers outdoors. I searched all over google and searched the forums. I know I need to supplement calcium because of acidic rain and such. My tap water has a pH in the high sevens, close to 8, perhaps this is due to calcium content? Would it be enough to water plants with tap water once a week or so? Using buckets ranging 2-5 gallons (planting late in season) I do not think I have access to calcium Rating: 5
