  • Helps plants grow happily and rapidly
Size: 4.5-Pound
At one point, my beautiful elephant ear was moving towards death after a nasty spider mite infestation. She lost a lot of leaves and looked very sad. I was looking for a fertilizer to help her recover, and just to feed all my plants. For a moment I considered a fish fertilizer, but everyone said it smells awful. I don't want my apartment smelling that way. I'm so glad I found this instead. It's dark brown, like the richest soil you can imagine, odorless, and a handful or two mixed into the upper inch of soil can fertilize plants for many months to come, slowly releasing more nutrients with each watering. This is the most natural way to go, and you can see how well my elephant ear recovered in the span of a few months. She's never looked better. ... show more

  • excellent for indoor cannabis
Size: 4.5-Pound
Been using for 7 days started late with my cannabis plant so I poured 4 (1/4 cups) on top of 7 gallon soil and watered. Only one plant, during my last measuring the height of plant grew by over 1" in one day. That was yesterday. It's going to be fun seeing if the growth is sustained until harvest. I don't expect to see continued fast growth, this event seems very unusual. I'll add more same amount in 4 weeks before flowering. I was afraid maybe I over dosed the 7 gallon growing container thinking maybe the plant will burn. No burning except I now have to raise my 480 watt LED light a few inches to insure leaves don't burn on the tips. I recommend this product to other cannabis growers. No bugs at all due to correct watering methods. I am disabled and limited physically and still I can grow. Buy this stuff, but not all of it so I can reorder in the future. I also used Roots dry nutrients that were 4 years old and still the plant has shown full growth. Roots dry nutrients if over used seems to not burn the plant either. Rising Foundation,Uprising Foundation and eventually Uprising Bloom mixed into 1 gallon RO water. Amazon carries the Roots dry nutrient line of supplements. It's expensive but so worth it. I am not a sales person just an old man growing some medicine. I grow organically. Best of luck to you growers. ... show more

  • Made a BIG DIFFERENCE in the health and growth of my plants!
Size: 4.5-Pound
I've never used worm castings before so when I looked into the importance of them I found out that the castings contain rich microbiological colonies that help fight soil-borne plant diseases and repel insects. Worm castings are water-soluble allowing plants to quickly and easily absorb essential nutrients and trace minerals. So I couldn't wait to see what they would do for my garden this year! Big WOW when my sprouts germinated! ALL of them came up and were very healthy. I didn't have any weaklings and nobody died on me! The first picture is when my tomatoes first came up and the second picture is one of many pickings of my tomatoes! Believe it or not THIS is just ONE day of pickings! Needless to say I made many jars of cherry tomato spaghetti sauce! It was so great! I'll never grow a garden with this stuff! ... show more
