PRO-MIX BX AGTIV REACH is a high-quality, peat-based substrate formulated for excellent drainage with enhanced microbial activity that supports vigorous cannabis growth. Made from sphagnum peat moss and coarse perlite, it has a light, porous structure that promotes healthy root aeration and moisture balance. With the addition of AGTIV REACH, a unique microbial inoculant, it helps improve nutrient availability and enhances nitrogen availability — giving plants a strong start during early veg. It’s an ideal substrate for growers using drip irrigation or hand-watering who want to optimize their root zone and increase overall plant health. For a peat-based substrate without microbial inoculants that contains a similar structure, look into PRO-MIX BX. If you want a higher biological boost with superior aeration, PRO-MIX BX AGTIV AMPLIFY is a great option.
