MAGNESIUM AND SULFUR BOOST

Photosynthesis is the process whereby the chlorophyll in the leaves converts sunshine and CO2 into sugars. It is the basis of ALL plant growth. No Magnesium, no chlorophyll, no photosynthesis. Sulfur aids in the formation of chlorophyll.

MAGNUM is our high potency Magnesium/Sulfur boost that will ensure an ample supply of Magnesium and Sulfur for chlorophyll synthesis.

Magnesium deficiency is the MOST common cause of poor yields besides overfeeding. The primary symptom of Magnesium deficiency is premature yellowing or interveinal fading of leaves. Sulfur deficiency is characterized by the fading of the veins.

Once yellowing is visible, CO2 consumption has slowed. That affects flower development.

• The most common cause of Magnesium deficiency is the high

Potassium/Phosphorus levels of bloom boosters.

• A secondary cause is overfeeding Calcium

If you are using Deep Breath to accelerate CO2 uptake, or you are using CO2 enrichment, the increased growth rate you expect to see will not happen if you have a Magnesium deficiency. Plants grown under normal CO2 will be even more impaired.

CAL-MAG IS NOT THE ANSWER

  • NO Cal-Mag product on the market contains sulfur
  • Magnesium and Sulfur deficiencies almost always occur together
  • Chlorophyll formation requires BOTH Magnesium and Sulfur

EXCESS CALCIUM CAN CAUSE MAGNESIUM/SULFUR

DEFICIENCY

Calcium and Magnesium are transported through the plant by similar pathways so the ratio of Calcium/Magnesium is important. The higher the ratio of Calcium to Magnesium the more the transport of Magnesium is impaired.

  • The proportion of Calcium to Magnesium in Cal-Mag products is way too high.
  • High Calcium levels “LOCK-UP” Sulfur which is necessary for the formation of Chlorophyll.

• Most Cal-Mags are loaded with Nitrogen (check the label) so you’re adding a “grow” nutrient right in the middle of bloom.

Remember, the Micro part of all 3 part base nutrient lines is loaded with Calcium so adding a Cal-Mag can lead to problems. We’ve actually seen a Cal-Mag product worsen a Magnesium and Sulfur deficient plant.

BOTTOM LINE:
TREAT A MAGNESIUM DEFICIENCY WITH MAGNESIUM AND SULFUR ONLY!

Chlorophyll deficiency in the bloom stage causes fading yellowing leaves right when flowers are putting on mass at a rapid rate. Magnum, with heavy Magnesium and Sulfur, will keep a plant’s energy factories optimized and the B1 helps relieve the stress caused by high performance bloom formulations.

Great, Affordable, Pump Sprayer
Size: 1-Gallon
This is an affordable pump pressure sprayer. It works the same as, if not better than, other higher priced sprayers I have used. Itnis easy to clean and has an adjustment tip to change the amount of spray and width of spray. With it only being 1 gallon it is easy to carry while walking the perimeter of my home to spray for pests.

Good
Size: 1-Gallon
I’ve used this sprayer for applying fertilizer, insect control, and watering plants, and overall it works really well for basic lawn and garden jobs. The pump builds pressure quickly, and the adjustable nozzle gives a nice range from mist to stream. I also like the translucent tank because it makes it easy to see fluid levels while mixing. The anti-clog filter is a nice feature and helped keep the spray consistent during use. It’s lightweight and comfortable to carry around the yard. The only reason I’m giving 4 stars instead of 5 is that some of the plastic parts feel a little lightweight, and I noticed a slight drip from the nozzle after extended use. Still, for the price and performance, it’s a solid sprayer and gets the job done well.

Well-made liner that ‘s heavy & durable
Size: 72"W x 78"L (Pack of 1), Color: 1a. Clear
These Barossa Design Long Shower Curtain Liner is thick, sturdy, and looks and feels noticeably more durable than standard liners. The heavier weight helps it hang straight without clinging, giving the shower a clean, polished look. It does a great job keeping water contained, and the material feels strong enough to last through regular use without tearing or thinning out. The length is ideal for taller showers, adding extra coverage and protection.

Great Quality and Perfect for Creative Projector Effects
Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear
Although designed as a shower curtain liner, I ended up using this for a completely different purpose and it worked perfectly. I placed it behind my study window as a projection screen for Halloween videos, and the results were fantastic. The material allowed the projector image to display clearly while still diffusing the light nicely for a great effect from outside. The quality was much better than expected, the material felt durable, and it was easy to position and work with. This product turned out to be incredibly versatile and offered excellent value for the money. If you enjoy creative decorating ideas or seasonal displays, this works brilliantly as an inexpensive projection screen alternative.

Perfect length and actually stays in place.
Size: 72"W x 75"L (Pack of 1), Color: 1a. Clear
This liner solved a problem I didn’t realize was bothering me until I switched to it. The extra length makes a big difference—no more water sneaking out onto the floor or the curtain riding up while you’re showering. It hangs nicely and gives a cleaner, more finished look compared to standard sizes. The material feels thicker than the cheap liners you usually find, but not overly stiff. It drapes well and doesn’t stick to you while showering, which is a big plus. The magnets at the bottom actually work and help keep it in place against the tub, especially if you have any airflow in the bathroom. Installation was simple and the reinforced holes seem durable enough to last. Overall, it just does what it’s supposed to do without any fuss. For the price, it’s a solid upgrade and something I’d definitely buy again.
