Turn your plants into champion producers with Overdrive®. With an NPK ratio of 1-5-4, this premium bud hardener invites your garden to maintain peak performance all the way to the finish line. Our team of scientists engineered Overdrive with ideal amounts of phosphorus and magnesium to create the optimal conditions for catalyzing energy transfers within your plants, so they’ve got ample opportunity to bulk up your buds before flush.

  • Plants continue packing on bud weight late in the game, resulting in heavy flowers
  • Creates conditions to provide an unexpected surge of energy for sustaining peak performance through your entire run
  • Robust nutrition optimizes plant life expectancy

Overdrive® is specially designed for use with diverse hydroponic growing media and all continuous liquid-feed growing systems such as aeroponics, drip irrigation and emitters, NFT, flood and drain, and deep water culture.

ATTENTION: Overdrive® is completely compatible with all pH Perfect Base Nutrients as well as with all non pH Perfect Base Nutrients and supplements and all competitors Base Nutrients and supplements.

NOTE: At Advanced Nutrients, we do not use paclobutrazol, daminozide, or any other banned plant growth regulators in our products.

Discover the Ultimate Trick Top Growers Use to Boost Flower Production During Final 2 Weeks Prior to Flush

Yes, it’s true. With the right nutrient strategy you can reboot flowering in the last quarter of your crop’s bloom phase. 

In fact, right now, growers in 117+ countries are increasing yields and crop value with a simple pre-harvest feeding trick.

Many are winning awards for the huge, potent buds they’re achieving. 

But it wasn’t always this way. 

For decades, growers tried everything to grow fragrant, stickier, fuller buds in the last few weeks of their crop’s life.

They bought the right lights. 

They hunted down exotic, cup winning genetics.

The most sophisticated base nutrients. 

Spent hours on forums pouring over expert advice.  

But there was still one thing they couldn’t control… 

The Inevitable Death of Their Cannabis Plants

Because here’s the thing…

Your crop has an “expiration date,” one that’s determined by both genetics and environment. 

By the time they enter the bloom phase, you’re practically counting the days until budding slows to a crawl and you’ve got no choice but to harvest.  

And while you might end up with mediocre yields, there’s nothing quite as disappointing as watching buds taper off in size and never quite reaching their full potential. 

In fact, in addition to biomass, you’re also harvesting before your plants ever reach the high concentration of trichomes and other valuable compounds you’ve sought out to cultivate. 

Fortunately, it doesn’t have to be like that. Not for you.


A Scientific Discovery Changed Everything

As cannabis experts, we knew there had to be a way to get more from our plants during those last few weeks.

So our team of Ph.D. scientists got busy…

We ran countless studies. Examined hundreds of tissue samples of plants during the final weeks of bloom. And researched the internal clocks of thousands of plants.

This was NOT an overnight fix

It took us years to get it right.

And when we did, the results were staggering…

We discovered that feeding plants an optimal ratio of nutrients in the homestretch triggers a second round of flowering late into the bloom phase—a time when most plants are slowing down and reaching the final stage of their lives. 

And here’s a fact that’s very important to understand, so pay close attention…

Your plants flower as a part of their reproductive stage, even if you’re growing unseeded female crops. 

So, as soon as they believe they’ve created seeds for the next generation, they’ll consider their work done. 

That’s what causes them to shut down and die. 

Understanding the natural functions that occur during the final stages of flowering— and why they occur—  was key to unlocking your cannabis’ full genetic potential.

Meet the Breakthrough Biostimulant that Sustains Peak Plant Performance Until the Moment You Harvest

 The result of these scientific discoveries is Overdrive®, the powerful late-season bloom booster that’s turbocharging thousands of cannabis harvests across the globe. 

Once you apply Overdrive to your grow, you’ll get optimal conditions to reinvigorate flowering so your plants can create: 

  • Sweeter, stickier, fuller buds
  • Increased cannabinoid and terpenoid levels
  • A harvest you can be proud of 

With the help of this premium biostimulant, your plants can focus on producing the valuable flowers you’ve worked so hard to achieve. 

You’ll be pleasantly surprised by the fuller, bigger buds. The potent aroma. The high concentration of valuable compounds

Overdrive can transform a stage of your crop’s lifecycle that typically leaves growers disappointed, into a harvest you can be proud of.

Join Thousands of Growers Improving Late Bloom Phase with Overdrive® 

Here’s what other growers have to say about Overdrive…

Growers who, like you, were counting on achieving massive harvests. Who knew that meeting their bottom lines was critical to their success. 

Like Zachary, from Winnipeg, Manitoba, who yielded a huge harvest

“I was nearing the end of the bloom cycle and the plants just were not producing. I tried several fertilizers, but none worked. The guy at the hydroponics store suggested I use Overdrive®. In about a week, there was a visible increase in flower size, and I got the large harvest I’d been desperately hoping for.”

Or Grant from New Mexico who said…  

“In the past, I had used only the base nutrients in the last week before the flush. But I was losing something in that. When I started using Overdrive®, I saw the buds get bigger during the last week. This is definitely the way to finish your crops.”

The fact is, we sell thousands of bottles of Overdrive every year to growers who have rewritten the script on those final weeks of their bloom cycles. 

To get started

Grab Overdrive from your closest authorized retailer (which you can find here)

Or you could do what some growers have done…

Then, use Overdrive in your next crop and see how much fuller your buds look

Put Overdrive to work for you today. And create conditions that…

  • Capture the thick, sticky resin

Over time, components within the nutrients settle on the bottom of the bottle. When you pour a bottle without shaking it, you can potentially be pouring out an unbalanced solution. Shaking up the nutrient bottle ensures you are pouring the right blend into your reservoir, giving your crops the nutrition they need.

Usually, it’s not a problem. But some products are incompatible with each other and can damage your plants when they’re used together. For example, bloom boosters with high PK numbers or low-grade silica products can destabilize your nutrient mix and cause nutrient lockout.

Nutrient manufacturers design their products to be used with each other. In doing so, they include specific portions of each nutrient in each product, so crops receive the right nutrition through each stage of the grow cycle. When you stick with one manufacturer, you don’t have to worry about inadvertently destabilizing your nutrient mixture. One example of why you need to stick with only one manufacturer’s products is Advanced Nutrients’ pH Perfect line. These products are designed to keep your crops’ root zone within a specific pH range. When you use them alongside products from another manufacturer, we can’t guarantee your root zone will maintain its optimal pH level.
