GrowTropicals Pumice (Fine Grade)

Pumice makes an excellent soil amendment providing structure, aeration and moisture regulation. Its porous surface absorbs excess moisture, releasing it steadily back into the substrate as required by roots. Pumice contains very few trace minerals but can be ‘activated’ by soaking it in a nutrient solution for 24 hours before use. Alternatively, you can combine it with Worm Castings for a natural, gentle nutrient source.

Fine Grade is measured at 1-3mm
