Join Us During our Field Trials

Our Goal is to foster support and funding for respected scientific research partnerships

David’s Farm: Iowa City, Iowa

Crops: Green star lettuce & Coastal star lettuce 

The farmer applied wood vinegar with the ratio 1:600 during the seedling stage 3 times per week.

He observed that: 

  • The wood vinegar treated lettuce had grown 26% faster, healthier and denser than the controlled lettuce

  • Wood vinegar helps the crops uptake and stimulates growth 

  • It improves absorption through the roots 

  • Strengthens the roots and leaves 

  • The yellowing of the leaves was minimized

  • Crops under wood vinegar treatment are stockiest/healthiest looking plants in the bunch

  • Wood vinegar has shown the capacity to work as an effective herbicide

  • Wood vinegar killed most of the weeds while still benefiting the main crop

  • Wood vinegar was able to increase lettuce yield by 22%

  • Wood vinegar treated lettuce was thicker, and bigger than the control lettuce

Seed Germination Trial: Iowa City, Iowa

Crops: Wheat grass (wood vinegar on left)

Two equal cups of wheat seed were weighted to 200g. One of the experiments were soaked in a container for 24hrs in water and the other one soaked in wood vinegar diluted with water, ratio 1:2000. The wheat seeds were laid out on a round tray and sprayed by a mixture ratio of 1:4000 to keep the seeds wet enough to aid germination. The other tray was fed with water only. Some observations:

  • Seeds soaked in 1:2000 showed signs of accelerated germination, proper root formation, and appeared more lush and thick.

  • Wood Vinegar nourishes seeds for germination and when used alone as a stimulant for seed germination has shown improved strike rate and time

  • This would suggest that wood vinegar used sparingly could provide enough to accelerate germination and growth.


  • After 10 days of each trial, watering was stopped. The wood vinegar treated trial appeared to remain green and lush longer than the water trials after treatment was stopped. The wood vinegar condition also remained hydrated longer than the water treatment.

  • Wood vinegar diluted in water also seemed to allow the medium to retain more moisture and could be potentially beneficial to reduce heavy water usage or increase the shelf-life of plant products.

VerdiLife is seeking farmers to work directly with us on practical field trials. Our team of scientists will collect data on a large range of plant varieties and applications. These trials are already being conducted with grower partners in Iowa and early results are creating buzz and excitement in our farming community.
