White Perlite 3L – Substrate Aerator for Indoor Growing

Frequently asked questions

• What exactly is white perlite?

  It's an inert growing medium that doesn't add nutrients or natural microbial life to the substrate. It's an artificial substrate that's already present in small amounts within many specific grow substrates.

• What proportion of perlite should I add to the mix?

  At GrowIndustry we recommend adding a maximum of 20-30% perlite to the growing mix. With that proportion you gain aeration without compromising the substrate's ability to retain water.

• Does it work for growing in soil and in coco?

  Yes, this bag of perlite is an ideal medium for improving substrate aeration in both soil and coco crops. In addition, some growers have gotten excellent results using it in hydroponics.

• Does perlite need to be prepared before using it in hydroponics?

  Yes, it's important to stabilize the pH at 5.5 before starting, to prevent your plants from being harmed by fluctuations. To do this, soak it for 24 hours and adjust the value until it stays stable at 5.5.

• Does it have any advantage against pests?

  It's a clean medium that's very unwelcoming to pests, as well as being economical. Since it doesn't contain natural microbial life or nutrients, it doesn't offer the environment that many unwanted organisms are looking for.
