Boca Hydro Magnesium Nitrate – 10% Mg + 11% N (Nitrate Nitrogen)

Premium-Grade Magnesium & Nitrate Supplement for Plants

Boca Hydro Magnesium Nitrate is a high-purity, fully water-soluble fertilizer providing essential Magnesium (Mg) and Nitrate Nitrogen (NO₃⁻) – two key nutrients for photosynthesis, chlorophyll production, and overall plant vigor. Our advanced formula contains 10% magnesium and 11% nitrate nitrogen, ideal for correcting magnesium deficiency and promoting lush green growth in all crops, especially under hydroponic or fertigation systems.

Sulfur-free and chloride-free. Safe for all crops, from leafy greens to citrus and flowering plants.

Supplies both magnesium and nitrate nitrogen in highly available forms.
Supports chlorophyll formation and photosynthetic activity.
Improves nutrient uptake and flower development.
Excellent compatibility with calcium nitrate and potassium nitrate.
100% soluble – ideal for hydroponics, fertigation, soil drench, and foliar feeding.

Unlike Magnesium Sulfate, Magnesium Nitrate can be combined in concentrate (dry or liquid) and applied with Calcium Nitrate and will not clump or lock.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Great price great shoe
Size: 12, Color: Burgundy Polished Full Grain
Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.

Quality shoe but with a slight squeak.
Size: 10 Wide, Color: Burgundy Polished Full Grain
Nice shoes with the classic Penny Loafer design. Fit was better than another brand I tried. Only reason not 5 starts is disappointment due to a slight squeak at times when walking.
