I’ve sourced Perlite from a few different places. This one is by far the best quality I have come across. The service from the guys at Dr Greenthumbs is always excellent also.

Go and Grow

This product is so easy to use and such an awesome source of food for all your leafy greens, but adding the same amount of Bud and Bloom to your fruiting Vegies and Bang, you've got your garden booming 💥.
Don't forget these products userly take about 2 weeks to break down. 👌✌️

My plants love this stuff; they are growing wild even through winter! I love that it's all natural and it doesn't smell like others I tried before.

Excellent quality

Great product to include in chunky aroid substrate - purifies the substrate and gives mature aroid roots in particular a great size chunk to grip on to.
