I find this to be very beneficial for applications to early season plants, i feel it nearly double lettuce production compared to a row I didn't spray in my greenhouse.

🌟🌟🌟🌟🌟 A Must-Have for Any Organic Grower I’ve been growing with living soil for years, and adding Fermented Plant Extracts to my regimen has been an absolute game-changer. You can feel the life in these brews — rich, potent, and alive with microbial energy. The results speak for themselves: faster growth, deeper greens, stronger resistance to stress, and undeniable terpene enhancement in flower. What I love most is how adaptable FPEs are — you can customize based on the plant phase (veg vs. flower), use them as a foliar or soil drench, and blend them with other natural inputs. It’s regenerative, sustainable, and gives you a real connection to your plants. Highly recommend to anyone serious about clean, conscious cultivation. These aren’t just nutrients — they’re plant intelligence in a bottle.

Smells crazy when you first open it but maybe I’m used to it now, stink in stink out as they say my plants have never smelled so terpy and extra extra sticky. A leaf was accidentally touching a bud yesterday so I gently tucked it away and it pulled away multiple hairs, the stank makes dank!

Starting using at 1 oz every 10 days and add a half once more each 10 day period and the rails are crazy! The trichome heads seem so much bigger. The smell is amplified. Looking forward to the next round using the comfrey through veg as well

Firstly, the gallon size saves you tons. It also goes faster than you'd realize if you use it how you should. It'll save you time by not having to order more so soon. Lastly, your plants will thank you.

The ferments are something I embrace. The plants here are standing tall in first light of the morning after they were fed the schedule with the COMFREY FERMENT the day before. The plants are a mix of mature seedlings (in black gallon containers) waiting to show their sex, along with two feminized plants in the fabric pots. They are a mix of Kid Kaya and Awkid plants along with Durban Poison. Use the ferments, if you want the best herb of your grow experience.

I got hip to the ferments from one of Jeremy's You Tube videos. I have been using them in my outdoor grow for the second year now. This year, they are putting vigor in my seedlings, all planted 4 to 6 weeks ago. I watered/fed them an hour ago. Look at how quickly they respond to the watering with Comfrey Ferment and the several amendments from the schedule.

This ferment as well as the others I have purchased have provided fantastic results. Foliar applications have helped keep pathogens at bay, while soil drenches have had the leaves reaching for the sun! I make many of my own ferments now thanks to Miles’ sharing his methods, but still come back and purchase to show some love and support

One of the best ferments for clones and seedlings and vegetative stage plants. I also use it on tomatoes, peppers, and some houseplants. Highly recommend! Also try the Peach Ferment for BLOOM stage, you won't be disappointed I promise! Happy growing 🪴🗣️💨

This ferment is perfect for the vegetation period. I use pumpkin during flower as well. Stink In, Stink Out!
