Customer photo review of GROZOME Bulk Plant Probiotics (50 lb.)

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.

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.

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.

GROZOME Worm Char

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 👌

Root Activator

My crop this year has had noticeably improved resistance to powdery mildew. The only difference is that I used the grozome microbe product.

Root Activator

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

Root Activator

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!
