Product Description
The Sensi two-component fertilizer line is easy to use.
A special formula gives your flowers all the micro and macro elements they need to optimally grow and produce flowers. Competitive fertilizers do not have the right combination of elements: tests have shown that some of them actually slow down and reduce flowering.Sensi Bloom 2-part contains various types of important and less important nutrients.
They are carefully arranged so that the plants produce delicious flowers. Sensi Bloom in 2 parts is a comprehensive nutrition program for hydroponic and more. Very easy to use. It ensures an increase in yield. If you want a richer crop and "everything that fits," select Sensi Bloom.
Use
- Shake well before use
- Use Sensi Bloom A+B only in the flowering cycle
- Add the same amount of "Part A" and "Part B" until you reach the appropriate nutrient content
- Do not mix together "Part A" and "Part B"
- Add "Part A" separately to the tank, and specifically "Part B"
- Mix both components of fertilizers A and B separately in water, do not mix together, except in water
Dosage
- 4ml/1L of water (from the 1st - 6th week of flowering)
- 2ml/1L of water for young plants
Sensi Bloom A+B 1 Litre Advanced Nutrients
Tired of pH ups and downs? Tired of dealing with pH pens? Then we’ve got good news: There is a new base nutrient formula that has a built in safety net, guardrails along the pH highway, that will perfectly maintain your pH without any work on your part. It will do this 24 hours a day, 7 days a week. That means no more pH ups or downs. Ever. And all you’ve got to do is pour it in.
But wait, there’s more! It’s actually 5 different premium products in 1 bottle. Which means that when you buy this special new formula, you’ll save hundreds of dollars a month.
Think of it… no more pH pens, which are expensive by themselves. Also, you won’t have to spend any more money or time to calibrate those pens. But the real kicker is you’ll also get the world’s best surfactant, fulvates, humates, and amino acids free of charge! Read on to find out how…
The Formula is Called pH Perfect Sensi Grow and Bloom A & B by Advanced Nutrients

Sensi-Grow/Bloom A & B is a two-part base nutrient formula that is ridiculously easy to use. You just measure the two parts, according to the mixing instructions on the bottle, and voilà. You can get on with your life. And because Sensi-Grow/Bloom A&B includes pH Perfect technology, your pH will constantly be maintained at the perfect level for optimal growth.
The technology is called “pH Perfect”
And our scientists are very proud of it. They ought to be. As long as you’re using pH perfect products, you don’t need to measure or alter anything to stay within the perfect pH range. Which means you can stop suffering with those dreadful pH pens altogether. pH Perfect is such a potent technology that it can bring a pH of 8.7 down to 5.5 in a matter of seconds. Or, it can raise a low pH of 4.8 to 5.5 in the same time.

5 Premium Products in 1 Bottle
Here’s what you’ll get when you use Sensi-Grow/Bloom A&B:
- Wet Betty – our prized non-ionic surfactant. A surfactant eases the tension in liquids so that your plants can feed more freely. Think of this as way to remove friction. It’s the difference between an old train on a rusty track and a Japanese bullet train that uses electromagnets to hover, so it can sail through the air at hundreds of miles per hour. Thing is, most surfactants could easily be replaced with dish soap, because they’re not researched and developed for the specific type of plants you grow. Wet Betty, on the other hand, has been painstakingly researched and developed, through 1000s of hours of plant-specific tissue sample tests. And you get it free when you buy Sensi-Grow/Bloom A&B.
- Grandma Enggy’s H-2 (Humates) – both the humates and fulvates we use are sourced from Leonardite, a rare volcanic rock that is one of the most mineral rich substances on the planet. Humates will boost seed germinating and root growth, as well as boost the power of chelation (which we’ll explain in just a moment).
- Grandma Enggy’s F-1 (Fulvates) – fulvates increase the permeability of plant membranes. These will work hand in hand with Wet Betty to make sure your plants can feed effortlessly. Like our Humates, and all of our products, the fulvates we choose have been carefully tested and selected for the types of plants you grow.
- 20 L-Form Amino Acids – while these are not currently a standalone product, we are including them in Sensi-Grow./Bloom A&B to bring you even more value. These special L-Form amino acids are powerhouses of plant growth. Just one of these, L-Tryptophan, has the potential to release bloom boosters that could give you the heaviest harvest of your life. And there are 19 others included. (It’s important to understand, L-Form amino acids are far superior to D-Form amino acids, which are used by most hydroponic nutrient companies today.)
- Sensi-Bloom/Grow A&B – Of course, there are the base nutes themselves. Not only do they perfectly balance your pH with pH Perfect technology, but they address every one of your plants’ 16 elemental needs. Going far above and beyond the call of duty, Sensi is much more than your average N-P-K (nitrogen, phosphorus, potassium). And each of the elements in Sensi-Grow/Bloom A&B is chelated to the highest quality standards currently possible.
What does this all mean?
To grow to their heaviest, full potential, your plants needs 16 elements.
Here’s how it happens in nature:
From the air, water and soil your plants get:
- Carbon (C)
- Oxygen (O)
- Hydrogen (H)
- Nitrogen (N)
From the soil and fertilizers your plants get:
- Phosphorus (P)
- Potassium (K)
- Calcium (Ca)
- Magnesium (M)
- Sulfur (S)
- Boron (B)
- Chlorine (CI)
- Copper (Cu)
- Iron (Fe)
- Manganese (Mn)
- Molybdenum (Mo)
- Zinc (Zn)
But if you want the best results, you’ve got to have the best versions of each of these. And in the right amounts.
That’s where Sensi comes in.
Sensi-Grow and Bloom have both been meticulously crafted to give you the perfect amount of each of these 16 elements.
And wherever possible, we’ve included the highest-quality chelated versions.
What is chelation? Chelation is altering an element at the molecular level by attaching tiny hooks all the way around the elemental ion that totally encapsulates it. And the surfactant (Wet Betty) relaxes the tension in the liquids of your growing medium so the nutrients can move freely. With these two forces working together, it’s like a feeding free-for-all for your entire grow cycle.
If you’re still not sure, let us take the risk:
All of it is guaranteed!

Try Sensi for yourself. Either Sensi-Grow, for your vegetation phase, or Sensi-Bloom, for your bloom phase. If you’re not blown away with how easy it is to use, how well it balances your pH, and how effective it is at growing heavy, profitable flowers, return the proof of purchase for a full refund. P.S. Some growers have reported that this two-part formula is even easier to use than a one-part formula, even without the benefit of pH perfect technology.

P.P.S. All that not good enough for you? Do you demand even more? You greedy son of a gun… we like your style. Check out pH Perfect Connoisseur, Advanced Nutrients’ most advanced base nute. The value you’ll get from pH Perfect Connoisseur is even more startling than Sensi-Grow/Bloom A&B.
