Lawn/Garden Planter pots from aircrete?

Can pots to hold plants be made from aircrete?
There are numerous YouTube videos about making lightweight flowerpots from hypertufa and papercrete. Can such items be made from aircrete? (A disadvantage of hypertufa and papercrete is that pots must be cured for a week to month before using them.)

The one video I found about using aircrete for a planter box determined that the particular formulation of aircrete he used had problem with cracking and bending. at 18:50
Possible, but it would be less convenient to maintain - will need to regularly add fertilizer, because aircrete is closed-pore composite, and therefore provide very few minerals to plants in the pot.
