VDL Perlite 100L – Perlite to Improve Aeration and Drainage in Crops

Frequently asked questions

• What is VDL Perlite 100L and what is it used for?

  It's a mineral aerator expanded at high temperatures, above 1,200°C, used as a substrate additive. It improves drainage, root oxygenation and water retention in indoor, outdoor and hydroponic grows.

• How do you use perlite in the substrate?

  The ideal amount is to add 20-30% perlite to the base substrate, mixing it with peat, coco fibre or soil. This reduces compaction, prevents root suffocation and protects the plant against overwatering.

• Does VDL Perlite affect pH or the plant's nutrition?

  No, it's a 100% inert, sterile material with a neutral pH, between 6.5 and 7. This prevents nutritional imbalances and ensures the roots have access to oxygen at all times.

• Can perlite be reused across multiple harvests?

  Yes, since it doesn't degrade over time, it can be reused across several harvests. That makes it a very cost-effective investment for both professional and hobby growers.

• What grows and fertilisers is it compatible with?

  It's compatible with every fertiliser line and can be used in both organic and mineral growing. It's especially useful in large pots, sub-irrigation systems, flood tables and any grow where you want to boost the health of the root system.

• What grain size does the 100L bag have?

  The VDL 100L bag has a medium grain size, around 1.5-6 mm. It's an ideal size to mix with soil, coco and custom blends without compacting the substrate.
