I used to replace the potting soil in my growbag garden maybe once or twice a year but have noticed that when I use this seaweed - regularly - in my growbag garden, though I still need to add compost, but I never have to replace the soil in the pots. Seaweed keeps them healthy and microscopically active. IT feels like a mini biome in a pot and the soil stays soft and healthy.I love this product. Love that it is clean too.
All kelp is great for seedlings and feeding the soil, but this form makes me much more likely to apply it since it’s so convenient. Just two teaspoons per gallon, and I can keep it handy since it’s not smelly (like fish emulsion) or in a huge bag (like the regular stuff).
Highly recommended! You only need a teaspoon of this per gallon of water. It’s very efficient and easy to use. And I use it all the time for soaking seeds, foliar sprays, etc. Much easier than buying a huge jug of liquid kelp.
Perfect for making compost tea.
Maxicrop is essential to keep in the bag of tricks for keeping the garden happy. Use it in my compost tea mix. Plants are always appreciative.
