Worm Castings tell me it WORKS!
I have never seen worm castings in my soil. Been using this every 3 weeks, for 3 about three months and I am seeing worm castings. Alot of people don't like worm castings because they are not pretty, but I love them because it tells me my soil is rich with microbes and worms naturally aerate the soil. This product works very well, super highly concentrated that goes a long way!

Clean,pure,high quality
Green leaf nutes produces high quality products for gardening and cannabis cultivation. Iv used kelp extract in both compost teas and foliar feedings for over 15yrs. This product is the most affordable on the market and is highly concentrated. A little goes a long way. If you value strong, healthy, vigorous plants. Buy this product!!

Need small amount only and quickly dissolved
Planted a chaos garden on the side of my house and i set up a solar watering system and dropped the pump into this 5 gallon container . I decide to add the kelp to my rain catcher can so it will be distributed directly to the roots . Im really excited to see how well this works . I added 1/2 tsp (2x1/4 tsp) to the 5 gallon can . Easy to use/measure and dissolved instantly which will be easy on the solar pump.

Good potassium source not quite a growth stimulant
overall very good but its not quite as good of a growth stimulant as other kelp feeds. I would honestly just use this if youre looking to add potassium to your soil i dont believe the hormones in this brands kelp are still effective once you get it.

Fantastic
For whatever reason this prime order was sent out through the post office and they lost it. Amazon immediately refunded the money then I found the product locally in a garden center. It works absolutely fantastic. I grow indoor mini tomatoes and mini sweet peppers over the winter plus a multitude of various house plants the seedlings are some of the strongest I’ve had in a long time and the colors are coming back on my silver dollar jades, and other succulents

Get it now. No regrets.
One of the very few supplements I run in hydro. This stuff actually makes a difference.

Great kelp extract
Very effective with visibly clear results in 1-2 weeks after use. Super for bottom watering and root hydrotherapy. My oldest and most ailing succulents are completely revitalized. Leaves are full again, vibrant colors have returned. Baby plants are loving the extract too.

Hard to be objective here as I probably need to wait all season. What I will say is, my plants are thriving after several have been potted on. Wear a mask when using though, the powder is superfine and is a bit of an irritant if inhaled. Does NOT block my superfine can rose.
