🌿 Boca Hydro Calcium Nitrate (15.5-0-0 + 26% Ca)

Premium Greenhouse-Grade Calcium & Nitrogen Fertilizer

Boca Hydro Calcium Nitrate is a high-purity, professional-grade fertilizer formulated to deliver 15.5% fast-acting nitrate nitrogen (N) and a superior 26% plant-available calcium (Ca) — far higher than the 18–19% found in standard double-salt products. Designed for hydroponics, fertigation, foliar feeding, and container gardening, our formula offers unmatched solubility, clean performance, and consistent results.

Calcium is essential for strong cell walls, blossom-end rot prevention, improved fruit firmness, and better shelf life, while nitrate nitrogen fuels vigorous vegetative growth without ammonium buildup. Boca Hydro’s greenhouse-grade purity ensures maximum absorption and precise nutrient delivery, making it trusted by commercial growers and home gardeners alike.

Working on Deep Wrinkles Great Results
I really like this product, it’s been working well on deeper wrinkles, especially on my forehead and around my smile lines. With consistent use, I can see a noticeable improvement in how my skin looks. The texture feels hydrating and smooth, and it absorbs nicely without feeling heavy. It leaves my skin feeling softer and more refreshed after each use. I also like that it helps with overall skin appearance, making it look more even and a bit more radiant. Minor note: Results take consistency, so it’s best to use it regularly to see the full effect. Overall, this is a great product for targeting fine lines and deeper wrinkles. Hydrating, easy to use, and delivers visible improvements over time.

Didn’t live up to the hype.
I had high hopes for this product. I’ve seen it all over social, but for me it didn’t live up to the hype. Although it is very moisturizing, it never dries down. There’s no way I could apply makeup over this, as the ads might lead you to believe. If you want a good night time moisturizer then this product is for you.

No Good
So I got this under the impression by the videos online that this was really concealing under the eye and it’s not…very oily and hasn’t done anything for under my eyes at all! Scam!

Helped My Texture & Pores So Much
Size: 2.03 Fl Oz (Pack of 1)
I bought this mainly to help with skin texture and the appearance of my pores, and it has honestly worked really well. After using it consistently, my skin feels noticeably smoother and looks more refined overall. I’ve especially noticed a difference around areas where I tend to have larger pores and uneven texture. My skin looks softer, more even, and makeup applies much more smoothly now. The serum itself feels lightweight, absorbs nicely, and doesn’t leave my skin sticky or greasy. It layers well with the rest of my skincare routine and hasn’t irritated my sensitive skin at all. I also love that the jumbo size lasts a long time, so it feels like a really good value for the amount you get. Definitely happy with this purchase and would repurchase again!
