Advantages

The advantages of Haifa Bitter-Mag

  • Fully water-soluble.
  • Consists of 100% plant nutrients.
  • Magnesium is an essential element in the chlorophyll molecule.
  • Safe for plants and humans.
  • Suitable for Nutrigation, foliar application and production of fertilizer blends and nutrient solutions.
  • Will cure magnesium deficiency in plants!

We are also a custom hydroponic and indoor garden nutrient manufacturer and we use Haifa Magnisal in our high quality formulas. You should also only use Haifa Bitter-Mag Horticultural Grade Magnesium Sulfate Epsom Salt Fertilizer for your hydroponic and greenhouse gardens since it's highly water soluble, great for foliar application, and is also great at the prevention and curing of magnesium deficiency in plants.

Haifa Bitter-Mag Horticultural Grade Magnesium Sulfate Epsom Salt Fertilizer combined with different calcium products are the two key ingredients to our calmag product MB R.O. Calmagic. Gardeners are wise to use R.O. Calmagic, or make their own products using only Haifa Bitter-Mag Horticultural Grade Magnesium Sulfate Epsom Fertilizer to cure magnesium deficiencies in their plants, which if left unattended can lead to death or a very weak harvest.

Solutions of magnesium sulfate are also nearly neutral, as compared to alkaline salts of magnesium, as found in limestone; therefore the use of magnesium sulfate as a magnesium source for soil does not significantly change the soil pH.

To avoid the formation of insoluble precipitates, do not mix any fertilizers containing calcium (calcium nitrate) with those containing sulphates (magnesium sulphate) or phosphates (monpotassium phosphate) in their concentrated form.

Composition

Haifa Bitter-Mag Horticultural Grade Magnesium Sulfate, Epsom Salt Fertilizer composition is approximately:

Magnesium:
Mg = 9.7%

Sulfur:
S = 12.8%

If you take (1) Gallon of R.O. water and add (1) gram of Bitter-Mag you would have 26ppm Mg Magnesium and 34ppm S Sulfur in solution.

My Monster Dogs destroyed these balls
Color: Glow in the dark II, Size: Large
I was so excited to get two of these balls for my doodle puppies to have to play with . THEY DESTROYED THEM IN ALL OF TEN MINUTES. I don't believe that there was anything wrong with the balls. They were beautiful, high quality balls. Just not durable enough for my doodles.

Sturdy, well made, puppy & senior dog approved
Color: Glow in the dark I, Size: Medium
Pet approved !!!! Our puppy immediately grabbed it by the straps and took off!! It is well made and has handled some serious chewing in the last 24 hours. We love the glow in the dark because puppy playtime does not stop when it gets dark out!! It came with a pump and was very easy to assemble and inflate. This toy would be great for a pet owner that struggles with grasp & grip strength, the straps are absolutely genius.

Fun, Durable Ball, But Straps Could Be Tougher
Color: Glow in the dark I, Size: Large
I bought the QDAN Glow in the Dark Dog Toys Soccer Ball for my German Shepherd, who absolutely loves it. The glow-in-the-dark feature is great for evening play, adding an extra layer of fun to our outdoor interactions. The ball itself has proven to be remarkably durable, standing up well to the rough play that comes with a large, active dog. However, the straps did not fare as well. My GSD managed to bite through most of them relatively quickly. While this hasn’t stopped us from enjoying the ball, it does mean that some of the interactive potential of the toy is lost. The ball continues to be a hit on its own, thanks to its resilience and the glow feature that keeps my dog engaged. If the straps were as durable as the ball itself, this would be a perfect outdoor toy for energetic dogs. As it stands, it’s still a good purchase for anyone looking for a sturdy, engaging toy for their pet, especially if nighttime play is a routine.

Pup loves this!
Size: 6 Inch, Color: Red
This soccer ball is so cute. My dog loves to play with these. The straps are durable, easy to pump up (they come with a pump), good value for the money since they tend to last awhile, at least for us. The straps are durable but could be an issue if your dog is an aggressive chewer. They stay pumped up for quite awhile and just need to be topped off once in awhile to keep the bounce there. We keep them outside even in the winter and they do just fine. HIghly recommend as a good play toy.
