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.

Comfortable and Easy to Wear Daily
Size: 2 Little Kid, Color: Navy/Blue
My daughter has been wearing these navy/blue shoes since the weather has been less rainy and more sunny. They are great for outdoor play, especially on days when it's warm outside. The knit mesh upper keeps her feet from overheating, and the cushioned insole feels supportive without being stiff. At size 2, the fit is accurate and the width runs a bit roomy, which gave her some growing room without feeling loose. The slip-on design with elastic laces and pull tabs is a real plus. She can get them on and off without any help, which she loves. The shoes are light enough that she barely notices them during long active days. My one small complaint is that the sole feels more like firm foam than rubber, so they can be a little slippery on smooth indoor floors. For the price, these deliver solid everyday value. They look good, hold up well to regular use, and my daughter reaches for them first most mornings. Pros: - Breathable mesh keeps feet cool - Easy slip-on design with elastic laces and pull tabs - Lightweight and comfortable for all-day wear - Accurate sizing with a roomy width - Durable for the price Cons: - Sole can be slippery on hard smooth surfaces - Limited outsole grip compared to rubber-soled shoes

Great kids' shoe — easy on, comfy all day
Size: 3 Little Kid, Color: Pink/Lavender
My kid has been wearing these for a few weeks now and I'm genuinely impressed with how well they've held up. The knit mesh upper keeps feet cool and comfortable during long days at school and outdoor play, and the cushioned EVA midsole does a great job absorbing impact. What really won me over is the slip-on design with elasticated laces and dual pull tabs — my child can put them on and take them off completely independently, which is a huge win. The fit is snug but not tight, and they run a bit roomy in width, which is great for kids with wider feet or those who need a little growing room. At $32, the quality feels solid for the price. Lightweight, breathable, and easy to wear — these check all the boxes for an everyday kids' shoe.

Cute, Comfortable, Light-Weight Shoes, Perfect for School
Size: 11 Little Kid, Color: Pink/Lavender, Size: 11 Little Kid, Color: Pink/Lavender
These have turned out to be great everyday shoes for my 5 year old. She normally wears a size 10, but since that size wasn’t available, I ordered the 11 expecting her to grow into them. I was pleasantly surprised that they already fit her pretty well. There’s still a little extra room in the toe area, but the shoes fit securely around her ankles so they don’t feel loose or slip off while walking or playing. She says they’re very comfortable and loves how easy they are to slip on by herself. The lightweight design is nice for everyday wear, and they’ve held up well so far despite being worn almost daily. They've become her favorite shoes to wear! Also the pink/lavender color is really pretty in person. Overall, I’m very happy with them and would order again.
