The fertilizer works great for healthy plant growth. It provides a balanced mix of nutrients that plants need. Easy to use and very effective for both vegetables and flowers.

One and done
One and done product. I use it in a Dosatron setup in my greenhouse at a very reduced concentration. My tillandsias, which get watered twice a day, have gone wild. The cacti and succulents are plump and happy. Improved nutrition has also reduced my pest load.

Severely expensive, but works.
This product is HYDROPHILIC to air moisture, so put it in sealed, smaller jars with moisture absorbers. I LOVE that there are NO artificial colorants - just pure fertilizer. This product is perfect in that nothing else is required, 2 tsps and I don't have to worry about burning the roots. My rare herb plants are perfectly green, and are growing extremely well. It's just that this fertilizer is just so darned expensive. I tried going to the website of one of their approved suppliers in Florida and the price is actually 50 cents more. I will buy again if someone gives me an Amazon gift card as a gift, or if I have a highly valuable plant that would necessitate I purchase this product, otherwise off to the local fertilizer plant. I can go to the local fertilizer plant and get 25 pounds of a different vegetable hydroponic powder for $30, but it also requires me to buy another bag ($25) of calcium nitrate pellets, mix separately, then add together - then I also have to worry about burning the roots. And now I have 50 pounds of product to last me to eternity. I had to remove a star due to cost, and the inability to get any meaningful discount for a larger size, but otherwise, a truly excellent product.

No mixing multiple nutrients
Seems easy to use but for houseplants you need to make sure your plants want extra nitrogen like my lilacs did not but that is my fault As for veggies it seems to help them grow fast but think I'll switch to an organic blend for edibles and use this for houseplants
