Review: Excellent liquid fertilizer product for home gardeners! - I needed a quality source of liquid fertilizer that I could mix in small quantities for my 2025 growing season of young vegetable transplants. I found the product to be simple to mix and it produced excellent results. It was recommended to me by some local greenhouse plant growers. I liked the size, nutrient balance, and value for the money to be excellent. My plants grew very healthy. I used it on flowers and vegetables.

## Questions & Answers

**Q: can this be used with a hose end sprayer?**
A: Yes-it dilutes with water very readily-follow instructions-I used to be in this business and this is one of the best fertilizers on the market.

**Q: Is this slow release pallets?**
A: No, you mix it in water and it dissolves immediately then spray it on your plants.  Works great BTW!

**Q: Will this work well for a ficus (rubber tree)?**
A: I use this on a number of my ficus trees, including elastica, Benjamina, and lyrata. I alternate between regular watrings and fertilized waterings, and then stop during the winter.

**Q: can this be used in hydro dwc?**
A: No this should not be used for hydroponics. It is formulated with urea, which is not the best nitrogen source for hydro. Urea is not readily available to the roots in hydro and also it may give you pH problems because it will acidify your medium.

### ⭐⭐⭐⭐⭐ So far, So Green and Healthy My Plants Grow with Jack's!!!
*by S***R on February 23, 2013*

I went with Jack's because I was reading a particular text indicating I should apply a 20-20-20 General Purpose fertilizer to my plants to get them a good, solid beginning. So I did it, and purchased a bucket. I bought the 8oz, and thought, "Why am I buying so little?". Well, now I know it isn't so little after all, I'll have this much Jack's for nearly 2 years. Essentially what I did was fill up an empty Cranberry/Pomegranate juice bottle (I think it is 96 ounces, total volume). I followed the advice of other reviewers, I only went with a capful and the whole bottle of water turned into blue-ish water. Once I saw that happened, I knew I had enough fertilizer mixture blended in. I made that batch about 3 weeks ago and still have some left as I am trying to not kill/burn my plants as a result of being impatient with the regular stages of growth. I don't want plants on steroids, I just want my indoors starts to start well enough to then go into the garden come the first moon of May. As I indicated, so far, so good. I see really deep greens in the leaves and the veins of the leaves are very conspicous. I have healthy plants. The reviews for Jack's are many and many of them were convincing enough to prompt me to pick up a bucket. The price is a little high, but it is nice to give Jack's the money instead of Miracle-Gro. Would I advise others that might be considering a purchase of Jack's to go ahead with their purchase? Yes I would. I would also quickly follow up and report that they truly only need a capful or less of the crystalline concentrate to blend in with a volume of water to come upon a really effective liquid fertilizer for their flora and fauna. Go buy a bucket. I would wager that you'll be handily impressed.
