GrowTropicals Lava Rock (Coarse Grade)
For the largest aroids with thick, strong roots lava rock may be the appropriate choice for that super chunky substrate mix. Its porosity lends itself to well-draining mixes. Lava rock is also often used as drainage and/or as the sole substrate in terrariums where the plants donāt require a high level of nutrients.Ā
Lava rockĀ is also greatĀ drainage material for vivariums.Ā Lava rock is a great substrate that has a high surface area making it an ideal filter/drainage material that won't break down quickly. We recommend covering lava rockĀ with a materialĀ such as horticultural fabric or synthetic screening to preventĀ smaller-grained substrate materials from filtering down into it.
Lava rock is also an excellent biological filter. The large surface area lends itself to a high volume of beneficial bacteria,Ā Nitrosomonas andĀ Nitrobactercomes,Ā that willĀ convertĀ ammonia into nitrite and nitrite into nitrate respectively.
