No, but this will be the third year I've used this product.

I soak all my transplants in it just before planting. Contains Bacillus pumilus and humic acid.
When planting seed I put the seed in the ground, wet the seed with the solution and cover (improves germination rate and sprout vigor). Then when the plants have their first true leaves I apply a drench to the plants. Works for me at little cost. Claud
