Description

Tribus Original is a groundbreaking organic microbial root stimulator for plants designed to revolutionize your gardening from seedling to harvest. Boasting 10 billion Colony-Forming Units/mL of Rhizobacteria, it delivers visible results in 24hrs, making it a game-changer for all growers. This USA- made, non-GMO and pet & family-safe product is OMRI-listed for organic use, ensuring it meets the highest standards for safe, organic gardening. Tribus helps optimize the intake of macro & micronutrients by enhancing root strength through its three growth-promoting Rhizobacteria - Bacillus subtilis, Bacillus amyloliquefaciens, and Bacillus pumilus. These bacteria work symbiotically with the plant by producing extracellular plant enzymes and other biochemicals that maximize nutrient availability and uptake. This results in bigger roots, buds, stems, grass & greater yields, and resilience against stress factors. With an application rate of just 0.5 mL per gallon of water, it's not only efficient but also cost-effective. This premium soil amendment is resilient to chlorinated tap water and remains potent for 18 months after opening. Applying Tribus is simple. Shake well and apply weekly or at each watering throughout the growth cycle. Safe for use up to harvest day, it can be mixed with water- based nutrient solutions or applied directly to the plant roots. The best results are achieved when mixed solutions are used within 24-48 hours. This root agent is also compatible with all fertilizers and growing media - soil- based, soilless mixes, and hydroponic applications. Whether you're a small- scale specialty crop grower, home gardener, or an organic enthusiast, Tribus offers a simple, powerful solution for plant care, promising lush, vigorous growth throughout all stages of plant development. Impello Biosciences is dedicated to creating effective & sustainable products. We utilize next- generation biotechnology to tackle agricultural challenges.

Just get it! Seriously, my first first indoor hydro foray was hit or miss until I got Tribus. Now plants are prolific with increased volume and growth rate. The difference is phenomenal. Before, I was dealing with intermittent damping off during germination and slow or stalled results. Some root browning and furiously cleaning with restarts. Today, about a week later, everything is growing gangbusters. I just woke up and saw ‘wow’ everywhere. I’m expanding operations. Hee. What I love: • The food grade organic naturalness with a pleasing to undetectable scent (fresh yogurt in the bottle to non-existent in the nutrient water solution). So much healthier and I feel less nervous about these newly easy grows. No weird colors anywhere. Clean! • How fast and thorough it works. Roots are white and abundant - so pretty. I can barely believe how quickly it worked. • A tiny recommended amount resolved every issue. I can even use less expensive hybrid grow mediums with zero mold, algae or fungus. No weird steps or H202 in endless cycles. Even the anemic plants rebounded faster than we can eat/harvest them. • I added it to a basil cloning reservoir and those cuttings shot out impressive roots without rooting gel. The microgreens that are prone to issues germinated faster, grew faster with beautiful root hairs and root structure - even the less ideal seeds I couldn’t sprout before were suddenly working. • The nutrient uptake is so much more efficient and water recycling is carefree, consciously sustainable. Tribus saves a bundle and a lot of time/stress. As I look at results before compared to now, I can barely believe it. I’m new to this (since November). I almost gave up, but we’re enjoying bounteous salads, herbs and microgreens plus 2 new DWC units with impressive starts to determinant small variety tomatoes and Fresno chilies today. We only commandeered a few shelves. Mediums range from an economy grow sheet of recycled tree fiber, to premium bamboo, to ebb and flow units, to coco coir flats, to kratky, to DWC… even the house soil plants and barked orchids, plus one decorative vertical wall planter are suddenly thriving. I’ve only used a few milliliters and suddenly it’s like paradise. I did get a little 3 watt submersible UVC bulb to treat water before adding nutrients and Tribus - just to give it the ‘edge.’ I keep a gallon circulating with an air stone and UVC, then I remove those, check pH and add the recommended amounts. I get so excited to peek at roots, white, thick and branchy with copious air roots above those now. The water levels decrease faster than before because uptake improved. The mini crops have better structure, like the heirloom lettuces display more color and they’re crunchy, so I’m sure Tribus resolved nutrient lockout issue plus inoculating whatever microbes were upsetting my plant babies. This is one apartment in the city turned into a beautiful mini farmer’s market kiosk on a few surfaces - urban tabling, food security and nutrient dense. Geez, the flavors! I’m gushing, but I’m just going to say it: we’re having fun, feeling healthier and happier to have found this. Everyone asks how I did it. I told them ‘It’s not me, it’s Impelio Tribus! It just wants to make things grow and grow!’ The yield though. We couldn’t eat all of this. My neighbors are happy. Our cat has a little 10 x 10 patch of oat and wheat grasses with barley and catnip too. Everyone is purring. Thank you Impelio! 💚 ... show more

    • All that and a bag of chips!
Size: 8.5 Fl Oz (Pack of 1)
this and their next product "continuum" are the best thing to hit gardening in my lifetime. im old. these products put a bacteria on your roots which eats the nutrients before the plants do. . then they secrete those nutrients in an easier form for the plants to digest. the result is far more complete nutrition and far healthier plants. (breaks it down into simple sugars) this food is absorbed far more efficiently. it forces you to use way less food. it takes a few feedings to take effect... but youll notice your plants getting hella dark green if you dont drop your npk. this is AWESOME if you have an "EC budget". in short once the plants have adapted to the tribus or continuum youll need to drop your By .3-.4 total ec. if you dont the plants will burn as if youre running too much feed. (because you are at this point). This gives me lots more room during flower for P/K and the extra calcium that LED's require. also... youll throw your rooting products away. this stuff builds CRAZY roots. dont use more than once per week at 1ml per gallon . youll have roots climing out of the pot from the top. i also quit running it after the last repot and not in flower. This stuff is a true miracle. its VERY effective and really works even better than they say. just dont try to use this without measuring your nutes with a truncheon or tds meter because its seriously that good. this is truly the future. i run this with canna coco nutes and ive had to drop my EC down to .4 on the base nutes after it starts working. (2 or 3 feedings to get the full effects). ... show more

    • Little bottle, big impact
Size: 100ml
Review Image by thedude thedude
I really like Tribus since it is one of the most concentrated bacterial inoculants on the market. It might seem a little pricey but since it’s so concentrated you get a good value for the money. The recommended dose is only 1ml/gallon of water so a small bottle goes a long way. The bottle they package it in is very functional allowing for easy dosing. So far my plants are a nice lush healthy green color and have been bulking up nicely in early flower. Will buy again and am interested in trying Impello’s newer bacteria product, continuum in the future. ... show more

    • Do the math, it’s concentrated
Size: 100ml
Too many negative reviews talking about this being too expensive relative to other products, which is hilarious, because it’s a much *better* value than every other similar product I’ve seen. See all those 0s at the end CFU counts? Yeah it’s a small bottle but if you check your calculator you’ll see it’s 100x or 1000x more concentrated than some of the others. Would you rather they have added 1000x as much water to the package so you would get, and pay to ship, a bigger bottle with less microbes in it? I prefer to dilute it at home. ... show more

    • Expensive but great value!
Size: 100ml
Yes, this product is expensive but contains more concentrated microbes than other products in the market There's supposedly 10 billion CFUs/mL. So when I say a little goes a long way, I mean a little goes a LONGGGGGG way. According to the instructions, my 2L watering schedule only needs 0.5mL which is about 12 drops. For those that are doing larger scale gardening, I like the different 5mL spout that would save an extra step of measuring. ... show more
