FAQs

Questions about hydroponics? You are not alone.

  • Yes! FloraSeries® is perfect for hobby and commercial growers alike. Because FloraSeries® components are in liquid form, you can quickly mix nutrient solutions at any scale, while maintaining precise nutrient ratios.

  • TriShield™ qualifies for exemption from EPA registration under Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) as a minimum risk pesticide. Approved for use on hemp, vegetable plants, and ornamentals grown both indoors and outdoors.

  • TriShield™’s active ingredients are Soybean Oil, Sodium Lauryl Sulfate, and Citric Acid.

  • Store in the original container in a cool, dry area out of reach of children and domestic animals. Protect from freezing. Keep the container tightly closed. When finished with contents, offer for recycling or dispose of according to local or municipal laws.

  • When diluted and stored correctly, TriShield™ can be kept as a ready-to-use solution for up to three months, compared to the hours-long usability rate of other pesticides.

  • As a minimum-risk pesticide, TriShield™ is scientifically proven effective against aphids, mite, and powdery mildew, while posing little to no risk to human health or the environment.

  • FloraPro™, by virtue of being a water soluble fertilizer, is concentrated and must be diluted in water. It can be diluted into the irrigation water manually, by employing a “day tank” system, or by using fertilizer injectors or chemical dosing systems.

    Nutrients
  • FloraPro™ is a blend of high-quality mineral salts, and is made with internal good management practices to achieve excellent quality standards. To maintain excellent quality, store as follows:

    • Store fertilizer in a cool, dry place out of direct sunlight
    • Avoid high temperatures or high humidity to prevent fertilizer from liquifying or clumping
    • Product is hygroscopic: substance tends to absorb moisture from the air. Opened bags should be closed tightly and stored in airtight containers to prevent hardening
    Nutrients
  • While FloraPro™ is a complete nutrition program, supplements can be used for additional benefit. FloraPro™ was designed to be compatible with existing Hawthorne Gardening Company speciality supplements.

    Nutrients
  • Purpinator® may be used on all plants on all plants, but will perform best on plants that express purple pigmentation 

    Supplements
  • If you are using a hydroponics reservoir system, it’s best to clean the reservoir as frequently as once every 3 to 5 days with a critical cleaning solution and to closely monitor for film developed along the surface. Critically clean reservoir systems are recommended

    Supplements
  • No, Purpinator® was designed to be fed as a root drench with water and is not to be sprayed onto the leaves of the plant 

    Supplements
  • Purpinator® can be used all of the way through your flush and will not leave chemical residues when used as directed

    Supplements
  • We recommend using Purpinator® in the vegetative phase to provide a stockpile of available compounds for use in flowering. If you are using Purpinator® for flowering only, start adding Purpinator® at the first signs of flowering site development or when you change light cycles 

    Supplements
  • Yes, but it is not necessary. Purpinator® has the same terpene and trichome benefits as Terpinator®, with the added benefit of improving purple coloration in genetically capable strains. Use Purpinator® for purple plants, Terpinator® for everything else

    Supplements
  • No, Terpinator® is not organic

    Supplements
  • No, Terpinator® does not contain these inputs. Triacontanol supplements can be used alongside Terpinator® if they are part of your feed regimen.

    Supplements
  • Terpinator does not contain Plant Growth Regulators (PGRs).

    Supplements
  • Terpinator® will remain stable for two years when sealed and stored in a cool, dry place away from direct sunlight. We recommend using Terpinator® within one year of opening. Do not store in areas with average temperatures below 40 degrees Fahrenheit. Do not freeze. 

    Supplements
  • No, Terpinator® is pH neutral.

    Supplements
  • An unopened bottle, properly stored (cool environment, out of sunlight, sealed container), can last for many years.

    Once opened, we still recommend storing in a cool, dark place, but encourage growers to use the bottle within 6 months.

    NutrientsSystems
  • Properly stored (cool environment, out of sunlight, sealed container) the FloraNova series should last up to one year without any problems.

    Nutrients
  • Either way will work. If you are using a nutrient for the first time and are not familiar with how it is going to affect your pH, you should mix your nutrient first. Let the solution sit for about 15 – 20 minutes and then check the pH and adjust accordingly. Keep track of how much pH Up or Down you add to the solution. Typically pH Up will be required if you are using Reverse Osmosis filtered water. If you are using unfiltered municipal water or well water with a pH of 7.5 or above, you might need to use a small amount of pH Down or possibly none at all. Once you know how much pH adjusting solution you use in your reservoir, you can add it first of you like. Remember that temperature affects pH so make sure your water temperature is consistent when mixing your nutrient solution.
