Raw Yucca acts as a surfactant, which reduces the surface tension of water effectively making it wetter, to improve nutrient dispersion and prevent the water from beading up. This helps the nutrients spread deeper and more evenly which is especially helpful for foliar sprays and soilless grow systems. Raw Yucca is excellent for nutrient flushing also. Raw Yucca is 100% yucca schidigera extract. Make your water wetter and improve your plant nutrition with Raw Yucca.
