Fern Mix - Premium Soil Mix - SYBASoil

SYBASoil Fern Mix – Technical substrate for demanding ferns

1. Expert introduction

The SYBASoil Fern Mix has been formulated to meet the specific needs of ferns, plants with fine, delicate roots that require a substrate which is at once rich, airy and constantly moist. This mix balances moisture and drainage to limit the risk of the roots drying out or suffocating.

In the TerraLED approach, a suitable substrate is essential for lighting and indoor conditions to promote healthy, lasting growth.
