Product Overview

Monkey Juice is a concentrated beneficial bacteria inoculant containing Bacillus subtilis and Bacillus licheniformis—two scientifically proven plant growth-promoting rhizobacteria. These microorganisms colonize root zones, enhance nutrient availability, suppress pathogenic organisms, and improve plant stress tolerance through documented biological mechanisms.

Modern growing practices often eliminate beneficial microbial populations. Sterile media, treated water, and chemical fertilizers create root zones lacking the microbial partnerships plants evolved to depend upon. Monkey Juice restores these relationships, establishing beneficial bacteria that protect roots, solubilize locked-up nutrients, and improve overall plant health.

Key Benefits

  • Bacillus subtilis produces antimicrobial compounds that suppress root pathogens
  • Bacillus licheniformis breaks down organic matter and solubilizes phosphorus
  • Both species trigger induced systemic resistance, priming plant immune responses
  • Spore-forming bacteria ensure product stability without refrigeration

Ideal For

Growers wanting natural root protection and enhanced nutrient cycling. Particularly effective in soil and coco systems where organic matter supports bacterial proliferation. The Monkey Juice + Sticky Bandit combination accelerates colonization and amplifies beneficial effects.

So far so good I made a few mistakes but the guys at Cronk nutrients of the absolute best! I'm expecting fantastic flavors, I've seen multiple YouTube videos with people using this product and the results I will be sure to update my review once the tomatoes are ripe ✌️♥️🙏🍅

Purr organics line

I've ran dwc for 3 years now with salt based nutrients and have done fantastic. The purr organics line should not be used in dwc type grows.. water gets foamy and roots seem to not like the supplements..that being said I've ran it in coco and perlite and have gotten great results.

Best decision in years

I was a faithful user of another brand.
I was never completely satisfied and started wondering what I was doing wrong. I discovered cronk, researched them and purchased a full auto line.

Early in my first grow I had to contact support.
The reply I received was the most professional super I have ever been given. It was expert support with both a scientific explanation. Footnotes with references to read.
They also offered an explanation in the vernacular for the layman.

The solutions worked immediately.

So. My take on Monkey Juice?
One of the best products I have used for my dwc. My advice for dwc. Use 1/4 dose every 2 weeks. A little dab will do you. Very economical.
