Have you ever used any nutrient line besides House and Garden? You seem very biased towards that brand. As a grower for many years I have realized that nutrient brands make very little difference!
First I want to say thanks for your question. So to answer the question, we have used almost every nutrient line that we carry in the store. When we started using House & Garden we were amazed at the results, both from the plants as well as the cleanliness and uniqueness of the product itself. When you find something that works so well why would you recommend anything else?
In your email you stated “that nutrient brands make very little difference!” I would have to disagree with that statement on some level. While yes all brands contain adequate levels of Nitrogen, Phosphorous, Potassium as well as the necessary micro nutrients, there are two things that really make the difference. First is the quality of the raw material and second the recipe, or ratio of elements like Nitrogen, Phosphorous, Potasssium etc, that the designing chemists come up with.
Have you ever seen white crystals form in the reservoir or on the pots after continuous feeding? This is a sign of a nutrient with way too much salt. All synthetic ( or mineral based ) hydroponic fertilizers are built on salt molecules however it is the quality of the raw material that will dictate how the end product will act. I have seen reservoirs using Aqua Flakes that haven’t been changed in two to three weeks that are still as clean as the day they were mixed. The purity of the raw material used to make the House & Garden products will absolutely be evident. Not to mention products like Roots Excelurator, Drip Clean and Shooting Powder…there aren’t any other products on the market that can compare to them. Then, after quality, you have to take into consideration the concentration of the products.
Drip Clean is used at 0.4 mL per gallon…a 250 mL bottle will treat over 500 gallons of nutrient solution. Roots Excelurator is used at just 1.1 mL per gallon, I dare say there isn’t another rooting stimulant this concentrated and for sure there isn’t another rooting stimulant that works anywhere near as well. Just ask Big Mike from Advanced Nutrients…below is a link to a video of the owner of Advanced Nutrients, Big Mike, testifying to the greatness of Roots Excelurator. The owner of a competitive brand saying how good Roots Excelurator is!! Need I say more??
So when you ask me if we are biased towards House & Garden I would have to answer YES we are. I am of the opinion that when people ask a question of the staff here at San Diego Hydroponics that they are asking for our opinion because they value our opinion. Our opinion is that House & Garden is the highest quality nutrient line available on the market today.
If you have any specific questions regarding other brands please ask and I will be happy to answer those questions as well.
