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.

Good product, the pump bottle could be better
Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50, Size: 12 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This is a usual product for me, I like and trust it. It has little smell, spreads on easily and can be washed off without too much trouble. The pump is nice while it works but I take away one star because it leaves about 20% of the product in the bottom of the bottle when the "cone of depression" gets lower than the bottom of the tube that brings the product up. After the pump can no longer effectively pump the product up, I cut the top of the bottle off and dip the rest out with my fingers. I'm not sure what they can do to make it work better but it's inconvenient as it is.

Excellent protection for workouts and hot days! ☀️🏃‍♂️
Size: 8 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This sunscreen is fantastic for daily use and outdoor activities. The SPF 50 protection is highly effective; I’ve used it under intense sunlight and haven't gotten burned at all. What I love the most is that it actually resists sweat and doesn't run into your eyes when you are working out. It doesn't leave an overly greasy feel, and the 8oz size lasts a long time. It is a reliable product that is always in my bag. 100% recommended purchase!

Very helpful
Size: 8 Fl Oz (Pack of 1), Style: Sport Lotion SPF 50
This sunscreen is a fantastic value, especially since I managed to grab it while it was on sale. It applies smoothly without feeling overly greasy and provides solid protection for outdoor activities. It is definitely worth picking up if you can find a good deal on it, as it does exactly what it is supposed to do. I will be keeping an eye out for another sale so I can stock up for the rest of the summer.
