OK, do you see how relatively easy it is to work with hypertufa ingredients?
The method shown to make the trough is rather “rustic” (many crafters take great pains to make more perfectly formed troughs), however hypertufa is supposed to replicate real Tufa rock, and the peat moss is supposed to deteriorate over time, leaving pits and crevices just like real Tufa.
So a haphazard approach when constructing a trough isn’t necessarily a bad thing. This type of construction method might very well give you a trough that ends up looking like you carved it out of a large hunk of Tufa. That could prove to be a pretty neat looking trough in your garden!
The only thing I feel the video should have included was adding drainage holes. I HIGHLY suggest that you make at least three drainage holes in the bottom of any hypertufa trough or ‘tufa planter.
You can use short pieces of ¾-inch to 1-inch dowels, or even short pieces of thick branches to stick into the bottoms of your hypertufa troughs. Or, you could just make ¾-inch or wider holes in the trough bottom. Just make sure your wet hypertufa recipe doesn’t “ooze” back into the holes you’ve made.
