Vermiculite - MEDIUM (2-5mm)

Grow Chem Medium Vermiculite is a natural, lightweight mineral that has been gently heated to expand into highly absorbent, sponge-like flakes.

• It acts as a natural reservoir in your compost, soaking up excess water and soluble nutrients, and releasing them slowly back to the plant roots exactly when they are needed.
• This 2-5mm grade is perfect for blending into container soils and hanging baskets to prevent them from drying out quickly in the summer heat.
• It also provides an excellent open structure, helping to insulate delicate roots against sudden temperature drops.
