3-Liter Bag of Perlite

Buy PERLITE 3 Liter Bag

Expanded perlite comes from hydrated obsidian subjected to high temperatures, which generates a porous grain with very low weight and stable structure. This material provides macro and micropores that increase root oxygenation, facilitate predictable watering, and reduce compaction in long cycles.

Thanks to its inert and neutral nature (pH range 6.5–7), it does not interfere with the nutrient solution, allowing precise adjustment of liquid fertilizers.

The PERLITE 3 Liter Bag works as a direct soil or coco enhancer, as a lower drainage layer, and as a rooting medium for cuttings.

In indoor growing environments, its physical stability contributes to fine root development and homogeneous colonization of the container, optimizing water and nutrient absorption.

Practical format to complement pots, transplants, and A/B tests. Available at Hydroponics Blanes, online grow shop, and trusted Grow Shop with discreet shipping throughout Spain.

Indoor growing PERLITE 3 Liter Bag

In indoor systems, perlite reduces the risk of waterlogging, stabilizes the water/air balance, and promotes more uniform root temperatures due to its insulating nature. This behavior is key under LED or HPS, where watering frequency can be high. Combined with coco fiber, peat, or plant compost, it maintains active porosity and improves response to drip or manual watering.

What is PERLITE 3 Liter Bag used for?

It is used to aerate mixes, improve drainage, increase capillary retention, and facilitate rooting in seedbeds and cuttings. It also acts as a base layer in pots, separating the substrate from the bottom and promoting excess drainage. In substrates for cannabis, it contributes to more active roots and sustained growth with less water stress.

Substrate PERLITE 3 Liter Bag

Material: expanded perlite of volcanic origin. Properties: extreme lightness, chemical inertia, sterility, pH 6.5–7, high water retention capacity while maintaining a stable air chamber. Presentation: 3 L bag, ideal for adjusting recipes without storing large volumes. Suitable as a component of the main medium or as an occasional conditioner in transplants.

How is PERLITE 3 Liter Bag used?

Mix with soil/coco: integrate 10–30% perlite by volume according to the goal; 10–15% for light aeration, 20–30% for more aggressive drainage and faster drying.
Drainage layer: add 2–4 cm at the bottom of the pot before filling with substrate; improves drainage and prevents basal compaction.
Cuttings and seedbeds: combine in equal parts with vermiculite or fine coco to obtain an aerated medium that stimulates callus and roots.
Inert hydroponics: use as an aerating component in custom mixes, controlling EC and pH in the irrigation solution.
Watering tip: as perlite increases, the substrate dries faster; adjust frequency and volume to maintain useful moisture without saturation.

Advantages of using PERLITE 3 Liter Bag in indoor growing

• High aeration: more oxygen in the rhizosphere and better root respiration.
• Fast drainage with reduced waterlogging and rot.
• Balanced water retention that cushions peaks between waterings.
• Inert, sterile, and neutral: total compatibility with fertilization programs.
• Light texture that lightens containers and facilitates handling.
• 3 L format perfect for fine adjustments, transplants, and small batches.
