SeaCom-PGR is a liquid plant growth regulator formulated to provide a high concentration (400 ppm) of the natural plant growth hormone; cytokinin. Cytokinin, combined with the diverse micronutrients in seaweed, leads to enhanced growth, and healthier, more productive plants.


Grass Micro-Greens Any other Sprouting Seed you wish to enrich.

Though we have only changed our Kelp supplier once in all our years, it is possible that it could happen again. Changing products on this site is easier then changing them on the old site, but if we change suppliers, and I forget to change the site - please don't get mad at me. As long as you read the product's label for instructions - it won't matter what Kelp you are using - you'll dilute it correctly.

I love this fertilizer. I not only spray it on my microgreens but also spray it on my herbs (makes them grow bigger). Its a small bottle but super concentrated. I've barely made a dent in my bottle and I've used it to make several batches.


it seems pretty good so far, one thing I know is that I'm going to be using it for my science fair project. ;^)

I found that using the Liquid Kelp Fertilizer during the soak phase of my sprouting made a noticeable difference in sprouting time and sprout robustness... RECOMMENDED.


I grew micro greens for years before I started using this really makes a difference in growth speed


This fertilizer speeds up the process of growing sprouts by about 30%. Add a few drops at the beginning of the soak and then again on day 3 & 4.
