Exfoliators Perlite Medium (Lightweight)

What is Exfoliators Perlite Medium and what does “medium” mean?

It’s horticultural-grade expanded perlite—lightweight, porous volcanic rock that boosts drainage and aeration. The “medium” grade offers a balanced texture: less dusty than fine grades, but not as chunky as coarse types.

Is Exfoliators Perlite Medium sterile, organic, or pH neutral?

Yes—it’s sterile, pH neutral, and free of nutrients. While not “organic matter,” it’s inert and safe for organic gardening. It won't affect pH or decompose in your mix.

What plants benefit from Exfoliators Perlite Medium?

Perlite improves root health in houseplants, seedlings, succulents, tropicals, and edibles. It prevents compaction, adds oxygen to the root zone, and reduces the risk of root rot caused by soggy media.

How do I mix Exfoliators Perlite Medium into soil or coco?

Blend 10–30% for most houseplants, 20–40% for tropicals, or 30–60% for succulents and cacti. For coco blends, 70/30 coco-perlite is common. Adjust based on drainage needs and watering habits.

Can I use Exfoliators Perlite Medium in hydroponic systems?

Yes—it works well in drip systems, Dutch buckets, and drain-to-waste setups. It can also be used on its own, but dries faster than coco and needs consistent feeding. Avoid loose perlite near pumps or plumbing.

Does Exfoliators Perlite Medium hold water or make soil dry faster?

It retains surface moisture in pores but drains quickly. It helps lighten soggy mixes, but may dry out faster—so balance it with coco or peat if you want higher water retention.

Should I rinse Exfoliators Perlite Medium before using it?

Yes—perlite can be dusty. Rinse with a colander or swirl it in a bucket to reduce mess and protect your lungs. Wet perlite handles better and is safer to work with indoors.

Why does perlite float, and how do I prevent it?

Perlite is extremely light and can float when watered heavily. To reduce float, pre-wet the mix, water gently, and consider topping with heavier material like bark if float becomes an issue.

Can I reuse Exfoliators Perlite Medium?

Yes, if cleaned properly. Remove roots, rinse thoroughly, and soak if needed to remove salts. While reusable, fresh perlite may be easier if it’s too fine or gunked up.

How should I store unused or opened perlite?

Keep it dry and sealed in the original bag or a tub to prevent dust leaks, moisture absorption, and debris contamination. Stored properly, it stays usable indefinitely.

Is Exfoliators Perlite Medium safe for pets, kids, or food gardens?

Yes—perlite is non-toxic and widely used for herbs and veggies. Just avoid inhaling dust and keep it out of reach of pets and small children, as it can be a choking hazard if ingested.

Can algae or mould grow in perlite?

Perlite itself doesn’t rot, but algae can form if it's kept wet and exposed to light. Mould is usually caused by decaying organic matter nearby, not the perlite itself.

Can Exfoliators Perlite Medium be used outside of gardening?

Yes—expanded perlite is also used in lightweight concrete, insulation, industrial fillers, and spill absorbents. However, Exfoliators Perlite Medium is formulated for horticultural use.

What’s the most common mistake with Exfoliators Perlite Medium?

Using it dry (dust clouds), or adding too little to make a difference. For best results: wet it first, use enough to change mix structure, and water gently to keep it from floating.
