Kim, See your post "timing confusion", it's not necessary to mist it unless you haven't leached out the lime. Billie

I haven't leached out the lime on anything, didn't even know about that. It would need to be completely submerged? Yikes! Don't think I have a container big enough for that...so if I misted instead, I should do that for two days?

Kim, Leaching out the lime is mainly a precaution for plants that are sensitive to lime. Also when the trough (or any cement item) is still new, every time you touch it with a wet hand or the troughs wet the lime can cause your skin to burn/peel. Some people are more sensitive than others. This is only until the lime leaches out. Originally people would let the hypertufa troughs sit outside so the rain or hosing off would leach the lime. Misting won't leach out the lime in two days. Billie

If you've got the space and the season allows, after the initial cure you can throw your piece out in the yard under a shady tree and hose it off every couple of days. Sometimes, I just fill 'em up with water and let them sit and change the water or hope for rain. I think that a vinegar wash will neutralize the lime.

Interesting information, thanks! My soil is very acidic, maybe the lime will help. Lucky me, I'm not sensitive to it.
