  • The Best of the Best of the Best! Try It, You'll Love It!
Size: 0.9lb (400g)
The best of the best of the best of the best... :-) I've used hydroponics nutrients since the 90s. This is the best I've found. I have used Flora Nova, Flora Series, Fox Farm and the other big name nute makers. This gives the best results. Lush, thick growth, no stretching. Great stuff. Strongly recommended. ... show more

  • It's strong but it works great
Size: 0.9lb (400g)
I used this on my GG-4 and it helped it exploded growth wise and when it started the flowering process I used the bloom enhancement from same company and it was just right. Be careful it's strong

  • Made In China?
Size: 0.9lb (400g)
This PKBoost seems to work okay, I’ve had some beautiful flowers at the end of the flowering season, but it’s hard to tell how much of it was due to this bloom boosting mix. You get a good amount of fertilizer for the price, and the size of the bag is fair. Be careful when applying this booster as it doesn’t take much to burn your plants. The color is almost pure white. It seems to work ok, I’m just not sure of the quality of the ingredients used considering this product is made in China and not Canada or the US as implied. This may make a difference to some people, and it should be known to consumers. I recommend this product if you don’t mind what’s in it or where it’s produced as you might be taking a risk. Be sure to flush your plants well after using Greenleaf Nutrients’ fertilizers. ... show more

  • Seller made everything right while Amazon and USPS dropped the ball.
Size: 0.9lb (400g)
I didn’t actually receive this item via Amazon because USPS spent weeks shuffling it back and forth between Cincinnati OH, Louisville KY (where I live) and Columbus OH. At one point, USPS told me I had to pick it up from a post office in Columbus, which is over 3 hours drive from my home. Eventually, they claimed to have delivered it, but it never arrived. However! The seller refunded my money and sent me a replacement. I cannot thank the seller enough for making things right! Excellent customer service! As for the product itself, I chose it because I wanted a High P-K and Low to No N fertilizer for my squashes and melons in my garden. However, I didn’t need a huge bag like most sellers offer. I selected the product because it was offered in a smaller volume, which will probably last me for a couple of years since I don’t grow a ton of squash or melons. So far so good on the results! My plants are putting out more blooms and subsequent fruits, which is exactly what I wanted all along. ... show more
