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.

Provides privacy without being stanoffish
Color: Steel, Color: Steel
Its a perfect way to get a lil bit of privacy, its the color steel. Its a little darker than the picture but it works. Free standing doesn't attach to furniture and takes maybe 10 mins to put together. It's about 5 feet tall. Very lightweight cover slides over the steel frame and zips st the bottom.

Perfect for my office space!!
It's a well packaged item including a simple tool set and a clear instruction. I put it together just by myself in about 15-20 minutes without any problems. The base is solid pieces of metal, and it stands very sturdy. It's also light enough for me to move it around in my office to serve different purposes.
I like the color and the quality of the fabric. It blends in with my office space perfectly. I needed it as a partition between my desk and the door, and the background for my video conference call. Surprisingly, it can also deflect the air coming down from the AC vent behind my desk. I didn't expect it to 100% soundproofing (not its purpose), but I feel it did absorb some humming sound from my mini fridge behind my desk.
I would recommend this to my colleague.

Perfect for my company's temporary needs
Color: Gray, Size: 72" wide, 66" Tall
My company ordered multiples of these dividers to separate desks in much smaller temporary space we had to use after our offices were flooded in August 2023. (Yeah, I know - just getting around to reviewing them now!) These fit the bill perfectly. Granted a bit of privacy so we weren't staring at the employee next to us. Easy to put together; excellent value.
