Prefer to grow with tap water? Jack's tap or "free nutrients" feeding schedule contains formulas that effectively provide all the necessary macro, secondary and micronutrients to complement water from many different water sources, like municipal and some well waters. The combination of the grow and bloom formulas utilizes the good nutrients that are found in water sources with higher concentrations of Calcium (40 ppm Ca or more). Add the Jack's Clone formula as well if you want to give a boost to your seedlings or clones.

See the nutrion schedule (Medical Herbs & Hemp Grown in Water with "Free Nutrients") on Jack's website for more details.
