Lettuce Formula (8-15-36) - Masterblend Premium Fertilizer
Masterblend 8-15-36 Lettuce Formula is perfectly formulated for hydroponic growing. Masterblend 8-15-36 completely dissolves in water with no fallout and will not clog sprayers or automated fertilizer delivery systems.
Normally paired with Calcium Nitrate and Magnesium Sulphate to offer a 3-part nutrient mix.
Note: Do not directly mix all three nutrients (Calcium, Magnesium, and MasterBlend Mix) together in high concentrations or Calcium will precipitate out of the mixture as a solid. Masterblend and Magnesium Sulphate can be mixed with hot water to ease dissolving (A-Solution) and Calcium Nitrate should be used as a second dosing solution (B-Solution).
Available in different sizes.
