Top Selling Product-Horticultural Perlite Standard graded for horticultural use, 2.0-5.0mm is used to improve aeration, water management and insulation properties for growing media.
Perlite standard has a neutral pH (6.5-7.5). Perlite is known for its excellent insulation characteristics, it also retains and conducts water and does not lock up nutrients. Perlite has shown to be extremely efficient in providing an increase in aeration as a consequence of its high air filled pore space. It holds less water than peat so the addition of Perlite Standard produces a well drained environment for root growth. It is also outstandingly efficient in stabilising temperatures. Perlite Standard should be used at 10-20% by volume. Video: If you are not sure what perlite does then click here to see an explanation on YouTube
