Product Description
Seedling Boost Fertilizer contains calcium, magnesium and a very high ratio of nitrogen in the nitrate form. The nitrate nitrogen will produce good hard growth, while the phosphorous levels will keep growth short and compact between leaf nodes. The stepped-up amount of potash will ensure good and healthy cell wall development. Seedling Boost Fertilizer can be used on vegetables, fruit, houseplants and ornamentals.

Note: This is the larger version of the Seedling Boost Fertilizer that comes with our All-Roots Seed Starting Kit

Directions

  • Mix ½ teaspoon of Seedling Boost Fertilizer in 1 gallon of water.
  • Two weeks after starting your seeds, supplement water in seed starting tray with Seedling Boost Fertilizer solution. Note: There is no need to remove water.
  • As your seedlings grow, use the Seedling Boost Fertilizer solution in place of water.
Product Details
