Tera Vita 90% Humic Acid Powder (Soluble)

• 100% soluble powder: Contains only minute levels of moisture (under 0.5%), with the balance all soluble humic acid.
• No soluble ballast: The manufacturing process eliminates the filler found in other "100% soluble" powders that contain lower levels of humic acid.
• Very pure: Pure enough to use in professional laboratory work, with a perfectly neutral pH of 7.0.
• Helps with clogging: If you have clogging problems with SP-85, this humic acid product should take care of them.

Rate: 1/8 teaspoon (not tablespoon) per gallon of water.

1. Do not add humate powders until you know the total amount of water you will use in your application.
2. Once diluted as far as it will be, add the soluble seaweed and humate powders on a per-gallon-of-diluted-material basis.
3. Add 1/8 teaspoon (level) of TeraVita SP-90 (or SP-85) soluble humate powder to each gallon of water.
4. More can be added in certain circumstances, but these rates give good results over a couple of months, especially if applied to both foliage and soil every two weeks, consistently, whether diluted in tea or in water alone.
5. These rates are minimums unless a higher frequency of application is being made, which must be addressed case by case.
6. It is much better to apply at lower concentrations and greater frequency than at higher concentrations and lower frequency. Too much of either ingredient can have the opposite effect on plant health and growth.
