This product is good but the 10lbs bag isn't. It arrived rock hard and I have had to break it up into pieces to be able to use it. It is cheaper but not worth all the effort to break it up. Will be buying a smaller more expensive container. You can see the container on the right where I already broke up some pieces to fit my 2lb plastic container. They need to work on some kind of humidity control or split packaging when selling these 10lb bags.

i received the 10 pound package and just used it. I can not rate the product yet but here my first comments 1- there is NO measuring spoon as they claim. 2- the zipper is not good so i was not able to zip the bag tightly to prevent moist.

Jacks makes the most effective powdered mix fertilizer on the market and has for decades. I’ve had better success with this stuff than anything else I’ve tried. Potted plants show an almost overnight improvement, with quick green up and increased vigor. 20-20-20 ratio plus minerals provides everything plants need in one easy mix. For flowers, use the Jacks Bloom Boost which provides extra Phosphorus. For everything else, use this.

This combination works perfectly for all type of plant. You get better healthy greens and blooming. I use to buy small one and found this is best deal for value for money.

The product is fantastic! The 10 pounder comes in a resealable bag, which is impossible to use. Forced to use a different container to keep the product from collecting moisture and hardening.
