These pictures show the results of a recent grow test done by Dr Senns team. The test was designed to determine the bottom end dilution ratios for blended soils.
The pepper plant on the left is the control with no Bio Stimulate.The middle plant had 1/2 ounce ABS per cubic yard. The plant on the far right- 2 ounces ABS per cubic yard.
Notice the root development directly proportional to the additive amount along with plant foliage development.
