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. 👌✌️

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.
