GS Plant Foods Cal-Mag Extreme – Advanced Calcium, Magnesium & Micronutrient Supplement for Plants – Strengthens Cell Walls, Prevents Deficiencies & Promotes Vigorous Growth – For All Plants, Lawns & Gardens

Correct Deficiencies. Strengthen Growth. Supercharge Results.

GS Plant Foods Cal-Mag Extreme delivers the critical secondary and micronutrients plants need for healthy, balanced growth. Formulated with highly available sources of Calcium and Magnesium, it also includes Sulfur, Iron, Manganese, Zinc, Boron, and Molybdenum to ensure complete nutritional support.

Calcium and magnesium are often overlooked—but they are essential for building strong cell walls, maintaining chlorophyll production, and supporting the transport of nutrients throughout the plant. Deficiencies in these elements can lead to weak stems, yellow leaves, blossom end rot, and reduced yield.

Cal-Mag Extreme prevents these problems before they start—keeping your plants strong, green, and highly productive.

 

💪 COMPLETE NUTRIENT SUPPORT: Cal-Mag Extreme provides essential Calcium (2.5%) and Magnesium (1.0%)—plus Sulfur, Iron, Manganese, Zinc, Boron, and Molybdenum—to correct deficiencies and maximize nutrient balance in your plants.

🌿 BUILDS STRONGER PLANTS: Calcium fortifies cell walls and prevents common issues like blossom end rot, while magnesium supports chlorophyll production for lush, dark-green foliage.

OPTIMIZES NUTRIENT UPTAKE: Enhances the absorption and mobility of nitrogen, phosphorus, and potassium—making your fertilizer more effective and reducing nutrient lockout.

🌸 BOOSTS GROWTH & FLOWERING: Strengthens roots, improves nutrient flow, and promotes more consistent flowering and fruiting across all plant types.

🌎 SAFE & EASY TO USE: 100% soluble and compatible with all fertilizers, hydroponic systems, and soil types. Non-toxic, environmentally safe, and suitable for all plants, indoors and outdoors.

Great sturdy wood shelf with metal pipes
I'm very happy with this wooden wall shelf. The material is wood, sturdy, easy to put together (did it by myself) and fit alllll the legos! I don't love the wood color but when the legos are on it it looks great. From The side the wood has a nicer finish so even though I thought about staining it I decided not too. I used my own anchors but had a tough time with them being too small. I'm Going to have to go back and fix but that's my fault. The pipes and screws provided are great-just not their anchors. Highly recommend. I might get another shelf from them for my other room.

Easy to install and excellent quality!
Size: 6 tier, Color: Black Brush Silver, Size: 6 tier, Color: Black Brush Silver
We moved into our house a year ago and I couldn't figure out what to put in this space. We considered installing our own shelves but then I found this! It fit the space and looks great! You can see in the bottom of the picture we ended up removing the bottom shelf and the feet that came with it in order to account for the narrow space of the baseboard but it was a quick fix and still looks great. This is also the EASIEST piece of furniture I've ever installed. It took me 10 mins all by myself and then my husband drilled in the top part to the wall. Still have some decorating to do but we couldn't be happier. The wood is real and the other materials are good quality.

Awesome Shelf for a Great Price!
The shelf is very sturdy and built well. I did not expect the quality to be so good. I honestly don't think you could build one with parts from the hardware store for less money. It was not very difficult to assemble, but it would have been easier if the were unions used with the pipes. I had to turn the whole shelf to tighten it. I also added some lights and the wires were difficult to snake through the pipes but I had planned on that not being easy. I did need help hanging the shelf. I don't think it can be done without help. I am extremely happy with the product and have got several compliments. Now I have to buy one for my mom because she likes mine so much. Shipping was super fast, it got to my house 1 day before I expected it. Thanks, I will be buying another one as soon as it gets back in stock

Looks great, not super sturdy
Size: 6 tier, Color: Black Brush Silver, Size: 6 tier, Color: Black Brush Silver
Putting the shelf together was simple and it looks nice. The shelf is not super study though. Word of advice, DO NOT use the drywall anchors that come with the shelf; buy your own. The instructions say to use a 5/16 drill bit and the included anchors. The anchors are terrible; the 5/16 bit was too big and the anchors went right through the wall when we tried to put the screws in. It was a huge frustration to put eight holes in the wall that we then had to patch up and repaint over because the included materials are terrible. Luckily a couple of the screws line up with the studs so it's fairly sturdy, but use our own anchors.
