You’re about to discover a brand new water-soluble powder fertilizer for growing clean, potent, heavy cannabis. It’s taken years to develop—yet couldn’t be easier to use.
And it’s going to help you grow buds that command top dollar… increase profit margins… and stand out in a saturated marketplace… WITHOUT shooting operating expenses through the roof.
In fact, we’ve run test after test on these dry fertilizers.
And every time, our cannabis reveals high percentages of the exact cannabinoid and terpenoid profile promised by its genetics.
The ROI is undeniable…
Because it’s the only water-soluble powder line that…
Hits the Shift Between the Grow Phase and the Bloom Phase
See, many water-soluble plant fertilizers claim they’re for cannabis. But look closely enough, and their labels tell a different story.
Because the reality is, your plants have very different nutritional requirements in the grow phase than they do in the bloom phase.
With most fertilizers, they won’t get the nutrients they need… In the correct ratios…at the right phase of development.
Miss this shift… and it can add up to BIG losses.
Hit this Shift, however, and you can rake in huge gains in yield, flavor, and potency.
Which is why our team of scientists applied 22 years of cannabis-specific research to innovate…
A Premium Water-Soluble Powder Fertilizer…
That delivers cup-winning results to commercial growers.
It’s called the Sensi Grow and Bloom Professional Series—and it’s the only base nutrient system that Hits the Shift— and meets the unique, phase-dependent nutritional needs of cannabis plants.
Not only is it insanely easy to use, it also makes it possible to…
increase yields…
… maximize cannabinoid production…
… and improve your reputation…
while enjoying a powder fertilizer that mixes easily and dissolves completely in large volumes.
And unlike generic alternatives that weren’t made for growing cannabis, these water-soluble plant fertilizers have been engineered to…
Optimize Plant Development From Seed to Senescence
When you put the Sensi Professional Series to work for your cannabis, you’re getting FOUR parts.
And the reason is simple…
Our scientists discovered that during the grow phase, cannabis needs MORE calcium, iron, manganese, and boron and LESS nitrogen, potassium, zinc and phosphorus.
And in the bloom phase, your plants are hungry for MORE nitrogen, potassium, and zinc (and a little bit more phosphorus)… and require LESS calcium, iron, manganese, and boron.
In other words, your cannabis nutrients MUST Hit the Shift…
So you can optimize every minute of your crop cycle with the exact cannabis nutrients your crop craves to unleash its full genetic potential.
Now, Hitting this Cannabis Shift simply isn’t possible when you squeeze cannabis micronutrients into one bottle.
What’s more, we’ve included…
Three Forms of Chelated Iron for Maximum Absorption
Because it plays a critical role in photosynthesis during the grow phase…
AND assists with uptaking optimal levels of nitrogen for cannabis…
So your plants can be well prepared to reward you with vigorous vegetation.
As you can probably tell, iron deficiency in cannabis can have grave implications for your grow phase.
But there’s a flipside to that, too…
We actually reduced the amount of chelated iron you’ll be delivering your plants in the bloom phase…
Because iron can interfere with potassium uptake…
Which is ESSENTIAL for maximum flower production.
This is why Hitting the Shift is so crucial… And why it can be extremely costly to invest in dry fertilizers that DON’T understand the phase-dependent nutritional needs of your plants.
Now even if we left it there, you’d be getting cannabis hydroponic nutrients that are FAR more specific to your crop than any other powder fertilizer on the market.
But we also used our 22 years of scientific research to ensure…
Your Investment Pays You Back in Dividends
With the Sensi Grow (Part A)™ + (Part B) Professional Series and Sensi Bloom (Part A)™ + (Part B) Professional Series, you’re getting…
- Powder fertilizers that meet the phase-dependent nutritional needs of cannabis — a critical factor for maximum cannabinoid production and yields
- More readily available nutrients to maximize economies of scale
- Three premium chelated forms of iron for increased absorption
- A dry fertilizer formulation rich in cations, like urea, to keep pH levels in the sweet spot
- Superior inputs and the strictest quality control measures
And you’re going to cultivate high volumes of compound-rich cannabis, stand out in an ultra-competitive marketplace, and claim your position in the upper echelon of commercial growers.
Imagine taking your grow to a whole new level — and gazing at hundreds of big, green, sugar-coated buds — by changing only ONE variable in your routine.
That’s the power of Hitting the Shift.

FAQ’s – Frequently Asked Questions
Can I run supplements with the Sensi Professional Series?
Definitely! While the Sensi Professional Series is a base nutrient and there are growers who do run it as a standalone feeding program, if you’re pushing your grow to its maximum potential, you could run all of your favorite supplements and additives with it as well.
Do I need to adjust pH?
Since it’s been designed around the work flows of a commercial grow environment, this is a nutrient where you’ll want to be adjusting your pH to the optimized range for your grow medium.
Can the Sensi Professional Series be used with coco coir?
Yes, you absolutely can use it with coco coir. Depending on the quality of your coco coir and your feeding practices, you may also want to augment your feeding with our Sensi Cal-Mag Xtra®.
Can I use the Sensi Professional Series in an irrigation system?
Yes! Using the Sensi Professional Series in an irrigation system is actually a breeze. Because the powders remain fully soluble once mixed with water, a properly designed commercial irrigation system should have no nutrient-related reliability issues.
Can the Sensi Professional Series be used with a dosing system, such as argus or dosatron?
You sure can. In fact, this is one of the reasons we’ve designed this as a two-part format. We’ve even included instructions on mixing concentrated stock tanks for dosing right on the bag.
