- Unleash Maximum Yield Potential by Making One Simple — and Invisible — Addition to Your Root Zone
Growing in hydroponics can be a catch-22.
You’ve chosen this indoor setup because it affords you total control over your grow room environment…
It’s the only way to be the full master of your domain.
And yes — a BIG part of the equation is selecting an inert medium like coco, peat moss, or rockwool…
Because they don’t contain anything that could throw off the carefully dialed-in decisions you’ve made for your plants.
However…
If you leave your root zone untouched, you’re missing out on the benefits of rich colonization…
Where millions of natural microbes power up your cannabis plants’ underground network for increased nutrient absorption.
Doesn’t it drive you nuts?
You can have the most dialed-in grow room on the planet. But if you don’t do anything about your empty root zone, you’ll never reap the benefits of nature’s genius.
Which is why . . .
Experienced Growers Colonize their Root Zone!
And add hand-selected strains of natural beneficial microbes to their growing medium.
Because here’s the thing…
When you unleash vast colonies of microbes into your root zone . . .
You’re creating the optimal conditions for building compound-rich biomass . . .
And walking away with higher quantities of potent, heavy flowers that put subpar bud to shame.
Imagine increasing your yields by making ONE small change . . .
And adding a root expander into your feeding regimen!
You see, your root zone acts like a highway for nutrients entering your cannabis plants.
And beneficial microbes expand this highway, making it wider and more productive . . . So crucial plant-potentiating nutrition can contribute to your most rewarding harvest yet.
In fact, we’d be hard pressed to think of a single cup-winning grower who neglected this much-needed root zone nourishment.
But keep in mind . . .
Some Microbial Additives Are a Total Waste of Money
Because they’re engineered to save the company on production costs . . .
And do nothing to help your root zone flourish and your yields thrive.
Now, in a moment, we’ll tell you EXACTLY what you DO want to feed your root zone.
But first, take a look at the red flags you must watch out for if you want to get a return on investment…
- If a company puts all their microbes and fungus into one bottle, they’ll likely go to war with each other. This results in a useless stew of ineffective microbes. Watch out for companies who use third-parties to bulk-produce bacteria — they’re solely interested in shaving down their own costs!
- Are your bacteria dead on arrival? When companies skimp out on proper bottling, millions of bacteria die before they even reach your root zone!
- All bacteria are created equal, right? WRONG! Only very specific strains of bacteria work to optimize YOUR specific plant root zone.
- Watch out for generic strain names… Otherwise, it’s like saying “General Motors” to describe a car, and having no idea if you’re getting a Pontiac or a Corvette.
- NEVER purchase so-called all-in-one solutions, where incompatible microbes live side by side. Some can dominate the others, causing the CFU of valuable strains to plummet over time.
As you can see, there’s a lot on the line when choosing the right microbial additives for your high-value, short-day crops.
And it’s important to do your research.
However . . .
We’ve made it easy on you.

FAQ's - Frequently Asked Questions
It’s true that we offer Voodoo Juice beneficial microbes and Piranha beneficial fungi, both of which have unique root and yield enhancing benefits. We offer those formulas and Tarantula because the combined array of beneficials when using the three together gives you the most dynamic, supernaturally-performing root zone that revs up your roots, plant growth, and yield. You can definitely use any of our beneficials by themselves and get optimum growth and yield, but used together, you get the nutrient healthiest and most productive plants possible.
Yes, extra sugars feed beneficial microbes and we’ve recommended CarboLoad as a food for beneficials. CarboLoad also has other benefits, but one thing you should be aware of is that we have combined CarboLoad with Sweet Leaf to create a powerful new formula called Bud Candy. We recommend using Bud Candy in conjunction with beneficials to give your beneficials the food they need.
Your plants’ roots will get as big as they can get, given the space they’re growing in. This will give you more root support for maximum yields. But we’ve never seen a case where the roots got so big that it caused problems for growers.
If you could import the richest, healthiest, most undisturbed and fertile outdoor soil into your garden, you’d have a rich broth of beneficial microbes. Although these beneficial microbes are present in fertile soil, you must provide them to your sterile hydroponic media. So by adding the right types of beneficial microbes to your hydroponic media, you ensure that only beneficials gain dominance there.
“I used to think it was great that we could have a sterile root zone in hydroponics. Then I realized that sterile means dead. There are good things that are supposed to be in the root zone. I had no idea that beneficial microbes are needed, but it’s true.”

“I live in a very damp climate and used to have lots of problems with roots going bad in my young plants. But after I started using your Tarantula I am having a lot more success and I wanted to thank you.”

“The people at the hydro store said that I could stop some root hassles with this. They didn’t say anything about getting larger flowers. I guess I was not expecting to see a bigger harvest. The only thing I did different was to start Tarantula in the middle of grow phase. So somehow what happened around the roots made the flowers larger in bloom!”
