I would like to set a 4x4 post (10 ft) in a tall, heavy plastic planter. I am using 2 50 lb bags of Quikrete. It says to just pour the concrete in, set the post, and then pour about a gallon of water in per bag. Then, directions say the water will simply saturate into the Quikrete.
I guess my question is: will the water actually reach all the way down to the bottom of the quikrete mix (maybe 10-12 inches down, at least)? if not, how much do I need to stir? And if i don't stir it vigorously, am i gonna wind up with a bunch of dry concrete mix at the bottom and properly set concrete on top?
Any help for this DIY newbie is appreciated!
