  • One bag of Mag-I-Cal® has the pH adjusting power of up to 15 bags of limestone!

Product Overview

Adjust your soil with Mag-I-Cal®! Jonathan Green Mag-I-Cal® for Lawns in Acidic Soil helps rapidly raise soil pH that's too low and stimulates healthy microbes in the soil. Healthy, lush lawns thrive in soils with slightly acidic to neutral pH levels ranging from 6.2 to 7.0. When soil pH levels drop between 4.0 to 6.0, this creates an environment for weeds to thrive and grows a lawn full of light green unsightly grass.

Mag-I-Cal® for Lawns in Acidic Soil contains pelletized calcium carbonate, or lime, in a completely soluble form that is immediately available to rapidly and efficiently raise soil pH upwards. Poor soil is often the problem in growing a great lawn and calcium is vital to many grass plant functions. Where it may take several bags of lime to balance low soil pH, Mag-I-Cal® for Lawns in Acidic has the power to do it all in just one easy application!

Additionally, Mag-I-Cal® for Lawns in Acidic contains humates to stimulate beneficial microbes in the soil.

Perfect travel pack
Perfect for travel. I have always used the Thayer toner but the milky toner is amazing. It great for the summer. It moisturizes without being to heavy. Theyre small and compact for travel. They last a long time, little goes a long way. I put mine in the fridge, it's so refreshing to use when cool on your skin

Skin feels fresh, soft, and super hydrated!
I love this set! The rose toner is perfect after cleansing — it tightens my pores without drying me out. The milky toner is my favorite at night — so hydrating and calming, especially with the mushroom + hyaluronic acid. My skin feels soft, smooth, and refreshed all day. Great size for travel too!

I was curious about this product since I saw it very viral on tiktok recommended by an influencer (Nina Pool) so I bought it, since it is small, I said: if I don't like it at least I didn't spend a lot. The truth is my skin is dry and I didn't think it would really work, and I can say that for being the first time that I let myself be carried away by those tiktok recommendations I loved it, mainly the milky toner I use it after washing my face and it leaves it very soft and when I go to put on foundation I combine it and it is incredible. I recommend it 100%
