Question: “What is the difference between dry and liquid nutrients?”     

Answer: Water! Ok, maybe a bit more than that depending on the ingredients used by the manufacturer. For inorganic liquid nutrients using the same or similar ingredients as we do, then water is the biggest difference. Most companies are taking dry, raw ingredients and dissolving them in water along with some food coloring and bottling them. Depending on the ingredients used, the solubility is usually 2.5-3lbs per gallon. The rest of that gallon is water! One of our 25lb bags would end up in 8-10gallons of water and would weigh 65-85 pounds! imagine what that does to freight cost not to mention storing all that water in containers in your valuable growing space.


Question: “Can I use mycorrhizae or other root inoculants with HGV nutrients?” 

Answer: Yes.  I am all for anything that helps develop and keep roots as healthy as possible. One of the keys to yield and quality is a strong, healthy root system.


Question: “Do I need to use Cal-Mag with HGV nutrients?” 

Answer: No. Our products contain all the Calcium and Magnesium needed to sustain healthy growth through all phases. Whether you use RO, well, or municipal water in your grow, you won’t need to worry about Calcium or Magnesium deficiencies if you are feeding correctly. 


Question: “Do I need to use flower boosters or finishers with HGV nutrients?”

Answer: No. Our nutrients are formulated to supply everything the plants need from start to finish. Unlike most companies, we don’t leave ingredients out of our formulas and make you buy them as expensive “additives”. If you feel the need to keep using these type of products, please take the time to do a side by side test to see for yourself is there is any benefit. Also, be sure you take into consideration and additional nutritive value of the additive as it’s very easy to throw off the ratios between elements when you start adding components to an already complete formula.  I have tested hundreds of “additives” over the years and if I found something that worked I would be incorporating it into our product. A proper environment and complete nutrient formula will give you far better results than trying to fix problems with some “magic additive”. If you are unsure as to what the effect might be of something you want to use with our nutrients, please email or call us so we can discuss it.


Question: “What about heavy metals in your product?” 

Answer: What would you like to know? Honestly. this is one of the most controversial topics these days and I could go on for hours about it. The important thing to realize is that every single nutrient line that is licensed and registered for sale in a state has gone through laboratory testing to be sure it meets federal standards for heavy metal content. This testing is public information and is available through your states department of agriculture. I encourage you to take the time and look up whatever line of nutrients you are using and see that they are compliant. Fancy marketing words like “pharmaceutical grade” or “technical grade” ingredients don’t make a difference in the end product in the numbers we are talking about here(parts per billion!).  If you really want to be surprised, check out all of the “organic” nutrient lines. I think you might be shocked at the levels they contain. And no, there is no such thing as “organic lead” or “organic mercury”. Take a look at the periodic table of the elements if you were sleeping during chemistry class in high school. And feel free to call or email me if you would like to talk about this subject more. I am never at a loss for words when it comes to this or any other topic about growing.


Question: “How do I make a concentrate for fertilizer injectors?”

Answer: Simple! First you need to know the ratio the injector is set for, and second, the size of your stock tank. As an example, if your injector is set to 100:1, it simply means that 1 part of your stock tank will go into 100 equal parts of solution. Ounces, gallons, milliliters, it doesn’t matter because it’s a ratio. Lets use gallons for this example though. If you have a ratio of 1:100 then one gallon of stock solution will be diluted into 100 gallons of water. If your target EC is reached by dissolving 6 grams(example only, you might need more or less) of nutrient into one gallon of water then you would add 600 grams into a gallon of stock solution to reach the same EC. If your injector ratio is set to 200:1, then one gallon of stock solution would go into 200 gallons of water so you would add 1200 grams to 1 gallon of stock solution to reach the same EC as 600 grams in one gallon at 100:1.

It’s important to note that you have to have separate concentrate tanks for the base formula and the growth or flowering formula. They can not be mixed together in concentrated form!
