great product from a good company
I like this fertilizer, it really helped my Lemon and Banana plants. I personally did not notice any smell as others have stated. The blue color is interesting, I cannot verify the content, but my plants perked up not to long after application.

A little goes a long way!
So far, so good. Works well for all of my indoor plants. High concentration so you only use a small amount. Packaging it came in was well done.

Great fertilizer with great results!
Great results for a flowering tree that was fading away. Within a couple of weeks after application of the fertilizer, leaves started to sprout fuller then orange blossoms started to bloom attracting hummingbirds and honey bees. A month later this flowering tree is flourishing. It should have been fertilized so much sooner.

Great healthy fertilizer
Had no idea how powerful this was. Put it on seedlings, killed them. But started to notice how quickly, the ones that did not die, were growing. love this, but don't put on seedlings.
