Monto Clay

What is Monto Clay? Monto Clay ®, short for Montmorillonite clay, is a proprietary fired clay product used to amend soil.

What sets it apart from other Montmorillonite products is the 1/4 inch particle size. Turface MVP for example is a great product but the smaller particle size can cause acidic shock and drainage issues. Ideal for use in bonsai soil, cactus soil, succulent soil, hydroponics and amending soil to increase drainage.
