I add Hygronated lime in 30 minutes, plz stop me if bad idea

I am going to put half cup of hygronated lime on top of soil surface because my soil ph is 6. Then I will water. Check pics and discription on action needed thread.

bump for your sake

how big are your pots and what are you trying to get your ph to exactly ? less is better as its easier to keep raising then to lower it again
