Best Perlite for Cannabis Buyers Guide
Perlite appears as small, white, round stones and is one of the most potent non-organic soil additives used to aerate growing media.
Many growers have heard of both perlite and vermiculite but it’s important to remember that the two aren’t always interchangeable and actually have different functions and benefits.
Although some qualities of vermiculite and perlite do cross over, vermiculite has much higher water retention abilities and is normally used to keep plants constantly hydrated.
Perlite meanwhile is much more porous and allows water to drain more efficiently. As such if you had a plant that needed only small amounts of hydration but instead of using perlite you used vermiculite you could potentially end up overwatering the plant and essentially drowning it.
Knowing the difference between perlite and vermiculite is therefore incredibly important and thankfully it’s fairly easy to tell the difference even from a cursory glance.
Perlite starts out as a volcanic glass that upon being heated to 1600 degrees Fahrenheit pops and expands to over thirteen times its former size.
But as perlite expands so does its porosity, and this means that it becomes unbelievably lightweight.
Perlite, once superheated, is made up of tiny air pockets and under a microscope the perlite surrounding these air pockets can be seen to be made up of tiny, absorbent cells that draw moisture to the exterior of the particle, thus making them perfect for transferring moisture to plant roots.
In addition to what we know about it how important it is to use perlite on the right type of plants, (ones that require limited moisture such as cacti), it’s also important to remember that growing plants in perlite can cause fluoride burns that present themselves as brown tips in most houseplants.
Prior to being used it’s always advised that perlite is sufficiently moistened to reduce dust particles but other than that perlite is very easy to use.
A perfect choice for plants that need high levels of humidity, perlites large surface area allows for increased evaporation and therefore improves humidity.
Many growers use perlite in soil mixes to change soil substructure, improve aeration and provide a well-drained, loose, noncompact growing media perfect for improving plant growth.
Perlite is an extraordinary and multifunctional additive to your growing media and providing you know what your plant needs, provides exceptional benefits with very few drawbacks.
