Humboldt Roots 1 gal.
Humboldt Roots is a highly concentrated organic root stimulant that expands the root zone during the critical growth stage.
The soul of every plant resides in the roots. Many gardeners neglect this fact and concentrate on the visual aspects of their plants.
A large yield is directly related to a plant's metabolism rates, and plant metabolism rates are directly related to their root zones' uptake of nutrients and fertilizers.
Humboldt Roots was specifically designed to expand the root zone, resulting in larger yields.
DIRECTIONS:
Always mix in non-clorinated water.
Soil: Mix 2 mL per gallon in non-chlorinated water. Use in conjunction with regular nutrient program throughout the vegetative stage and first three weeks of the bloom stage.
Hydroponics: Mix 2 mL per gallon in non-chlorinated water. Use in conjunction with regular nutrient program throughout the vegetative stage and first three weeks of the bloom stage.
Propagation: Mix 2 mL per gallon in non-chlorinated water. Soak rooting media with mixture prior to placing cuttings. Use throughout rearing stage. Suitable for aeroponic propagation.CONTAINS NON-PLANT FOOD

General Hydroponics pH Up Dry 2.2 lbs Base
To maximize plant growth, the pH content of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5. Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because our formulas are pH buffered. However, some important exceptions do exist. Acid content can reach unacceptable levels when nutrient solutions are mixed with poor quality water, or pH unstable media - such as rock wool and gravel products - are used, and when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop.pH Up: Base formulated using Potassium Hydroxide and Potassium Carbonate. Add a little at a time if your nutrient pH is too low in order to raise the pH to the proper level.
