Why HGV? They aren’t like other fertilizer companies. Their fertilizers stand on their own containing all the essential elements needed for healthy plant growth without the need for expensive “additives”.
HGV is formulated for the correct balance between all the elements. Many elements are antagonistic of one another, meaning that high levels of a particular nutrient in the soil can interfere with the availability and uptake of other nutrients. By using “boosters” or “additives” you are throwing off the delicate balance between each element that has been carefully calculated and proven to provide superior results.
They also source the highest quality raw materials. We have tested every form of N (nitrogen), P (phosphorus), K (potassium), as well as secondary and trace elements, and only use what has given the best results time after time in our own commercial facilities. No Ammoniacal or Urea products are ever used. While we could make a lower-cost product, that is not our focus. Quality is always at the top of their list, and it should be at the top of yours as well.
HGV nutrients can be run at much higher EC levels than many other brands due to the raw materials used to blend them. No ammonium and balanced levels of other essential nutrients allow for stronger feeding without the risk of burning or damaging your crops.
All HGV products are licensed and registered which means they have passed stringent testing protocols for metals and other contaminants that the Department of Agriculture requires. We have never had a customer fail product testing due to the use of HGV in their nutritional program.
HGV has recently built a new state-of-the-art manufacturing facility in Los Angeles, CA.
HGV is one of the only fertilizer companies that make every batch on-site using blending equipment that was designed and custom-built just for us. Most companies simply farm out their manufacturing to the lowest cost “toll blender”. They are not involved in the production or quality control of their product or even the sourcing of the raw materials used to make it.
They have over 600,000 cubic feet of climate-controlled storage for all of our raw materials which gives them an advantage in today’s unstable global markets. They have also sourced all of our materials from the same suppliers for over 30 years which leads to the batch-to-batch consistency as well as stable pricing and continuous supply our customers rely on.

HGV Top 10 Frequently Asked Questions
What’s the best way to use HGV fertilizers effectively?
For professional growers, it is standard practice to dissolve entire 25lb bags of HGV fertilizers into 10 gallons of water, forming highly concentrated stock solutions. Each HGV fertilizer: base, grow, and bloom should be dissolved into its own separate nutrient tank.
Once fully dissolved, these liquid concentrates or stock solutions can be used like any other liquid fertilizer: added to a reservoir or water storage tank.
It is quite common to rely on fertilizer injectors to accurately dose the concentrated HGV fertilizer solutions into the drip irrigation system, simultaneously feeding water and nutrients to the crops. This is called fertigation.
What additional fertilizers or supplements do you recommend using with HGV fertilizers?
The simple answer is none whatsoever. Plant fertilizers are made of plant essential nutrients, and HGV provides enough essential nutrients when used as directed. Adding more fertilizer on top of what is provided will likely do more harm than good.
The starting formula is already optimal, so adding additional ingredients will only bring you further away from what is optimal. It really can be that simple. Not convinced?
That’s okay. We recommend conducting at least one complete crop cycle using only HGV nutrients. We are confident you will be blown away by the results. Then if you insist on additional fertilizers or supplements – do so slowly one at a time – and track your results. Simply put: if you aren’t getting noticeable differences in yield or quality, then what’s the point? Over the years, we’ve simply noticed no differences when adding expensive fertilizer supplements.
We encourage our customers not to buy into hype products or gimmicky marketing. Plant nutrition can be boiled down to plant roots absorbing the correct quantities of dissolved mineral salts and living their best lives. Remember that sometimes less is more and more is not always optimal.
Are HGV fertilizers compatible with all types of growing mixes or hydroponic cultivation methods?
What about growers using potting soils or growing in the field?
Yes, HGV fertilizers are compatible with all hydroponics, soilless, and potting mixes commonly sold in the market today. HGV nutrients have been extensively tested in coco coir, stone wool (rockwool), peat mixes, and hydroponic liquid cultured systems.
For growers growing in field soils, we recommend a soil test be conducted first. For questions, please contact our technical support teams here
I am attempting to grow with very hard or very soft/reverse osmosis water. Should I take any special precautions or considerations?
In general, very hard or alkaline waters carry a high pH and contain high levels of calcium, magnesium, and sometimes chloride and sodium. We recommend conducting an irrigation water suitability test from a certified agricultural lab. Our technical team would be glad to go over the results with you and make any adjustments to the nutrient system if needed. In general, an acid will be required to neutralize excess alkalinity and lower the solution pH.
For growers using very soft or reverse osmosis (RO) water, irrigation solution pH and substrate pH becomes more difficult to control. This is because very soft waters lack natural water buffers that help regulate pH. This may require more careful monitoring overtime to avoid pH drift and possibly include adding bases to the nutrient solution to correct pH.
Quick Guide on Monitoring solution and substrate pH
Growers using a drip system: place an extra dripper in a beaker at the end of your rows and check the pH daily. Toss the irrigation solution at the end of each day and reset.
Place a few plants per bay or grow room on pot risers, with a plant saucer under each pot. Measure the pH at the end of each day. Toss the leachate solution at the end of each day and reset.
Use these basic techniques to ensure your pH is within an optimal range, particularly for those growers with very soft waters.
How long do HGV fertilizers last?
There is no expiration date for HGV water-soluble fertilizers! Once HGV fertilizers are made into liquid concentrates, they can last many months if properly stored and if the grower is using clean water and properly sanitizing all surfaces. Since the latter practices are harder to standardize, it’s generally best to plan to make enough liquid concentrate to last a month or two, then thoroughly clean out the liquid concentrate tanks and repeat.
How do you recommend mixing HGV fertilizers?
Here are some general tips and tricks:
- Start with hot water if possible. This will greatly speed up the dissolving process.
- Remember that the fertilizer salts will increase the volume of the stock solution. If you need to make 25 gallons of concentrate, don’t use a 25-gallon reservoir, size up at least 5 gallons to be safe.
- Use a light-tight reservoir or tank with a sealable lid. Keep in a cool, dry place away from direct sunlight or extreme temperature fluctuations.
- Use a powerful agitator like a paint mixer and drill.
- Slowly add HGV fertilizers to the water tank while agitating.
- Remember to never mix up different HGV fertilizers in the same concentrated stock tank. Extreme precipitation will occur. Each fertilizer: Base, Grow, Bloom should have its own concentrated stock tank.
- The fertilizers will be ready to use once they are clear and homogeneous and no undissolved bits of mineral salts are visible.
- Seal the stock tanks and label and date each one.
- There is no need to continuously agitate the fertilizers once they are mixed, but if the grower desires to do so use a paint stirrer or other method to stir the concentrate. Pumps and air stones are NOT recommended.
What is the maximum solubility of HGV fertilizers?
Maximum solubility refers to the highest mass of fertilizer that can be stably dissolved in each volume of water. Keep in mind that the maximum solubility changes based on temperature, the hotter the water the higher the solubility and vice versa. As the fertilizer dissolves, it will lower the temperature of the water which may make it difficult to fully dissolve if you are near maximum solubility rates. If you are using room temperature or colder water, reduce the amount of dry fertilizer per gallon.
- HGV Base fertilizer has a maximum solubility of 3.0 Lbs./gallon.
- HGV Grow and Bloom fertilizers have maximum solubilities of 2.5 Lbs./gallon
What’s the best way to store HGV Fertilizers?
HGV fertilizers should be stored in a cool, dry place to avoid clumping or caking. It’s important to understand that dry water-soluble fertilizers are inherently hygroscopic, which means they will take up water over time. This is natural and unavoidable if given the right conditions. Therefore, extreme hot or cold and particularly high humidity should be avoided to keep HGV fertilizers flowable. HGV fertilizers are manufactured in a sealed, climate-controlled facility using the best equipment that avoids breaking up or shearing the fertilizer salts (which also leads to caking). However, once it leaves our factory, it’s difficult to guarantee the product will not cake if improperly stored. It’s therefore important to have a dedicated storage area that is climate controlled if our customers wish to avoid caking completely.
Is caked or clumpy product defective?
No, the product is completely fine to use and there will be no difference in performance. It’s important to understand that the chemical makeup of our fertilizers does not change based on if it has absorbed water, or the mineral salts have adhered to each other, forming clumps. Therefore, caked, or clumpy products are not defective, or will perform differently.
One difference is that the fertilizer(s) may have absorbed water if left in a hot, humid area. So the best practice would be to fully dissolve whole 25lb bags of clumpy product in water, to ensure all the fertilizer is used at once.
What’s the best way to use caked or clumpy product?
Clumped product should first be broken up into smaller chunks if necessary. Get some hot water ready. Begin by slowly adding the broken-up chunks of fertilizer to the hot water (the hotter the water, the faster the fertilizers will dissolve). Using a paint mixer head on a power drill or similar will make the dissolving process much faster. Continue to agitate until the fertilizer solution is homogeneous, and clear, and no undissolved bits of mineral salts remain.
