Ideal for large flat-roof buildings and apartments.

Suitable for low-sloped residential roofs and retrofits.

Prevents Root Rot

Another result of increased Oxygen levels and improved drainage is that aerobic (air breathing) bacteria populations remain strong which keep the disease causing anaerobic (non air breathing) bacteria at bay.

Reduces watering requirements & water evaporation

By top dressing your pots and planters with a one to two inch layer of ECA evaporative losses are reduced which effectively conserves water and increases the time between watering.

Blocks algae and fungus gnats

A top dressing of ECA also serves to block direct light from reaching the growing media which prevents problematic algae from growing on its surface. This 'dry' top dressing also deters fungus gnats from colonizing your containers with their root destroying larvae.

Provides physical stability

When growing outdoors with a lightweight media such as coco pit etc., , blending some ECA into the mix will give planters the extra weight they need to resist getting knocked over by wind, rain or small animals. (cont.....)
