How To Store

HGV Nutrients are delivered in a dry form for many reasons, including to save you money on freight and storage space. However, dry storage requires certain environments and strategies to keep the product from absorbing or adsorbing moisture and becoming a wet, sticky mess!

Keep It Stable

Fluctuations in temperature will play a role in caking or liquefying. Whenever possible, regulate your storage temperature to be consistent, with a temperature range no larger than 5 degrees Fahrenheit (we store ours between 60-65 degrees). This means keeping it out of sunlight.

Keep It Separate

A dedicated storage area for your nutrients is always advised, particularly if you can separate your nutrients from fluctuations in air temperature or exposure to moisture.

Keep It Dry

Humidity or other sources of moisture should be avoided in storage. Remember that HGV nutrients are water-soluble and will take on water if exposed to it.

Keep It Cool

Very hot or cold temperatures should be avoided to keep HGV fertilizers flowable. We manufacture our nutrients in a sealed, climate-controlled facility to ensure quality control for as long as possible. By storing in a fairly cool environment, you can extend this level of climate control to avoid clumping and caking.

When to store as a liquid

If you do not feel confident that you can properly store your dry nutrients because of a lack of control over temperature, light, or humidity, we recommend turning your HGV formulas into liquid concentrates as quickly as possible. The advantage of this is that when a liquid concentrate is sealed tightly it will not absorb (dilute) or adsorb (evaporate) moisture from or into the air even with temperature and humidity fluctuations. You should still avoid fluctuating temperature ranges whenever possible, but as a liquid, your formula will remain more stable than it will in dry form.

Making a Liquid concentrate

If you need to make a concentrate, here is the simple recipe! The maximum solubility at room temperature for HGV is 2.5 pounds per gallon of water, so a 25lb bag will be dissolved in 10 gallons of water. Using hot water greatly speeds up dissolving the powder. If your bags are wet inside, be sure to rinse all the liquid from the bag into your container!

If we do the simple math, 2.5lbs is 1135 grams. 1 gallon of water is 3785ml. At that rate, 1 gram of powder will be equal to 3.3ml of the concentrate. So, if you multiply the grams of dry powder you currently use per gallon by 3.3 you will know how many ml’s of the solution it will take to reach the same ec you get with the dry form. For example, if 7 grams of the dry powder in one gallon of water gets you an ec of 1.8 then 23ml of concentrate in one gallon of water should get you to an ec of 1.8! Don’t panic if you see a little variation as it’s very simple to adjust by adding a little more or a little less concentrate or water to hit the target EC you are after. An EC of 1.8 whether from powder or concentrate is identical in elemental levels.
