Mammoth P Active Microbials

Best microbial booster for gardeners seeking higher yields and nutrient uptake.

This microbial booster acts as a biological key, unlocking phosphorus and micronutrients that would otherwise remain trapped in your soil or substrate. It requires a bit of extra management in your feeding schedule, but the trade-off is significantly more vigorous growth and noticeably heavier yields.
