Healthy plants start below the surface.
Give your plants a healthier foundation with the GROZOME Soil Health Starter Kit.
This three-product system brings together GROZOME Plant Probiotic, Soil Charcoal, and Root Activator to support the soil, beneficial microbes, and roots your plants depend on.

With smaller sizes of all three products, this kit is an easy way to experience the GROZOME system and is ideal for houseplants, containers, raised beds, vegetables, herbs, flowers, and smaller gardens.

Overall rating: 4.7 / 5 from 24 reviews.
I’m very much into soil health and this bio Char by Grozome is by far the best. I’ve tried a few other brands, but this one is superior to all of the ones I’ve tried. I’m excited to continue to amend my Sandy soil and have a spectacular cottage style garden each year.
My bed has be thriving after applying grozone!!!
So far I have been using Grozome on my fancy Chrysanthemum collection, and the weather has been hot. However, they seem to have nice roots, white and fluffy after a couple of uses. I soak a bag of grozome in a 5 gallon bucket and use to water the plants, and I think they are looking good. Normally growers use a lot of fertilizer, but I have been using just a little organic feed, watering with grozome and my plants are looking healthy. I think it is helping the soil in the pots and the roots start to feed each other, so I don't need the chemicals.

Store owner replied: Hey Lillian, Fantastic to hear that GZ is helping your mums weather the extreme NC heat this summer. Deep healthy roots are critical to in achieving vibrant, healthy plants without relying on excessive fertilizers. Thanks again for sharing your success story with us, and we look forward to being a part of your future gardening endeavors via the Chrysanthemum Club!
The orchids are LOVING the Grozome being added to their weekly/ bi-weekly watering routines. I have 13 plants currently blooming and preparing to bloom this season, which is a new record for me, YAY! (Winter is the blooming season for a lot of window-sill orchid growers. I'm planning to show off and brag about Grozome at the local orchid society's show and sale the first weekend of March.
After watering my houseplants with Grozome extract only 2 times my plants sent out new nice fresh growth, especially the Pothos, even my cactus, and the orchids bloomed!
I’ve had a Christmas Cactus for a few years with occasional blooms. After using GROZOME for the last couple of months the cactus exploded with multiple blooms.
Easy to use, all my plants love it, no burns.
I have been loving using this product and sharing it with my clients to help bring more life into our Colorado clay soil. It’s been helpful as well for my raised vegetable beds and indoor plants.
Still learning about the best use of your products. But I am a believer in soil health
It definitely helped to get a nice finish to the flower. With a smooth, clean burn after 12 days of drying and only 2 days jar curing. Well done!!
Definitely noticing a positive effect in all my indoor plants in all stages of growth to boot.
I have been using a 1/2 lb of Grozome with a 1/2 lb of my vermicompost to add diversity. I run it through the planter at planting time in furrow right on the seed in the seed trench. Then I use the same lbs/acre of both for a residue digester after harvest
WOW, Warm Char is super easy and works! I have added biochar to my wormbin in the past but it never made up all of the bedding. I found that it helped control odors and prevented the bedding from getting too hot when i added a lot of nitrogen rich material like ground flour to help speed up population growth. I got the idea from a youtube video in which the author experimented with adding biochar to the worms feed. The theory was that the biochar acted as a microbial reef and since composting worms eat microorganisms that have consumed food scraps the protective environment for the microbes resulted in more microbes and more feed for the worms. It worked well for me and seemed to allow me to feed more in a shorter period of time but breaking up the biochar can be a headache...this product saves me a lot of time.
I am really glad to learn of this product. It never occurred to me to use biochar in conjunction with vermicomposting, but as smell has always been the prime detractor indoors, this seems logical. And excited to see how adding Worm Char to bins will improve my worm casting supermix and how it will perform.
As you can see 👀 the grozome root activation and the charcoal has been great so far 👌
My crop this year has had noticeably improved resistance to powdery mildew. The only difference is that I used the grozome microbe product.
i really loved this product would highly recommend this product for others it really helped my plants
Works amazingly well
Awesome fast shipping . Yet to use but clear instructions and super excited
Thanks for the root grow I can tell it to early if I could have about a month then I can give another review so gorilla it's looking fine
Store owner replied: For our Root Activator, you should only use is once or twice in growing season. Remember, more is not more. Due to the acidity, adding more than what the directions suggest could throw off soil pH if you are not careful. Some folks actually need to low pH due to their native soil type, so this could be useful of a non-synthetic chemical means to do so. FUN TIP: Try using it (undiluted) on a pesky insect issue ;)
How come there's no information about which microbes/bacteria it's derived from? How do I know you're not using another product and then relabeling it and calling it your own name as if it's your own product but in reality you are using some cheap product that you break down into smaller batches and charging 10 times more for it?! None of your products disclose what they are made from. I find that to be very unprofessional and sneaky and not transparent about what your product is made from and what actually gives those benefits. For this exact reason myself and a few commercial growers are not going to use this products! BUYER BEWARE!

Store owner replied: Hi Dick, Transparency is very important to us, second to quality and consistency though. On our Home page (in the main header) is the link to all our third-party testing reports (https://grozome.com/pages/analyses-quality-testing) which has the DNA reports on all the beneficial biology in GROZOME, which are updated annually. GROZOME has been applied to 40,000 acres this past Spring, to some of the largest organic and regenerative farms in America. We do not take this trust lightly. Our product is literally under the microscopy daily by our product team, our customers and our exclusive partner for big Ag distribution - Hiwassee Products. As far as ingredients, they are all listed on our website on the "what is GROZOME" page.
