Excellent product
Excellent product. Though the container is very compact, it is so concentrated that it is a very good value for the money. Very easy to use. So far, my orchid seems to be responding well. Works great. No problems.

Great for Jasmine !
Worked perfectly for my Jasmine. I tried it as well for my anthurium and waiting the result. Make sure to wear gloves while using it. I felt some little burn sensation on my skin when I used it without gloves. Make sure to follow the dose instructions.

Pay attention to the size you order - 8 oz is good for maybe 10 watering can fills
I don't yet know how good the product is, but head's up, the 8oz container is basically sample size! I should have paid more attention to the weight, I'll own that - but I bought this for my outdoor flower beds and pots and used the entire container in a single day! Just like Miracle Grow, it comes in a plastic bag. When you pour that into the plastic container, it only fills it halfway. 😠

Container smaller than it appears
Beware, it’s a tiny 8 ounce container that looks like the standard 2 kg (4.4 lb) container but is only a half pound (8 oz. ) . But it’s priced like the 2 kg container!!!
