  • American Hydroponics Dark Energy 1 Gallon

    Not for sale in Oregon

    Dark Energy is a select blend of L-amino acids, specifically chosen for each of their beneficial effects on plant growth. L-amino acids improve the absorption rate of your favorite fertilizers by chelating essential nutrients and making them more available to your plants. Dark Energy enhances the bloom stage of any plant by stimulating the natural production of ethylene, a flowering and ripening hormone. Trials have shown that an increase in ethylene concentration results in a reduced time to harvest and synchronized, even ripening. You will notice an increase in overall biomass and harvest quality through continued use of Dark Energy.

  • General Hydroponics Case (12) General Hydroponics pH Up 1 Quart

    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.
