Hypertufa is a rock like concrete planter that is much lighter than straight concrete.
Anything from a plastic container, flower pot, stainless steel bowl, plastic bowl, boxes etc can be your molds.
All the supplies are available for about $20.00 – $25.00 and this is plenty to make probably 6 – 8 things depending on the size.
The first batch I tried equal parts of Portland Cement, Peat Moss, and Perlite. I found this to be a bit too crumbly.
Next, I tried 1 1/2 times Portland Cement to 1 part everything else and this seemed to work out better. Let it sit for a few minutes to see if the texture is sort of like oatmeal add more dry ingredients or more water to get it the right consistency.
Spray molds with a nonstick spray and start putting in the mixture molding it to the sides and bottom as you go. It is sort of like a texture type clay mixture.
Place it in the bag for 48 hrs turn the mold over gently to release on a flat surface let dry another 24 hours. Then place in the sun for a week or so. After that soak it in water overnight and then it is ready to plant in.
Notice all the textures that show up in this planter it makes for a very natural looking container that is very lightweight. The Aloe Vera is very happy in it.
I will be making a few more things now that I have the ratio figured out correctly. I want to do a big trough.
