Humboldt County's Own Magnum - Magnesium/Sulfur Supplement with Vitamin B1 - 2.5 Gal

Magnesium Support for Heavy Flowering Feeds - 2.5 Gal Jug

Magnesium sits at the center of the chlorophyll molecule, so a shortfall slows photosynthesis and holds back growth. Heavy potassium bloom boosters can make that shortfall more likely. This magnesium/sulfur supplement with vitamin B1 gives your feed program a dedicated magnesium source, so you treat the deficiency directly instead of guessing with a blended product.

The 2.5 Gal container suits growers who run a regular indoor or hydroponic cycle and want a steady supply on the shelf. It is sold individually, so you can start with one and reorder as your feeding schedule shows how much you use.

Key Features & Benefits

• Magnesium/sulfur formula — supplies magnesium for chlorophyll production along with sulfur.
• Added vitamin B1 — included to help plants handle the stress of demanding flowering regimens.
• Works with common base nutrients — fits into most existing feed programs without a change of base line.
• 2.5 Gal container — a larger volume for repeated use across cycles.

Who Should Use Humboldt County's Own Magnum

Growers who run high-potassium bloom boosters, feed high-value crops, or do not use a magnesium-rich base line will get the most from it. It suits home gardeners and licensed commercial growers who want to prevent deficiency rather than react to yellowing leaves.

Frequently Asked Questions

Q: What does this supplement do?
A: It adds magnesium and sulfur to your feed, with vitamin B1 included. Magnesium is needed for chlorophyll, which plants use for photosynthesis.

Q: Will it work with my base nutrients?
A: The manufacturer states it works with all popular base nutrients. Check your own base line's label for its magnesium content before adding more.

Q: Why not use a calcium-magnesium product instead?
A: Calcium and magnesium compete in the plant, so extra calcium can make a magnesium shortfall worse. A magnesium-only supplement targets the deficiency directly.

Q: What are the signs of magnesium deficiency?
A: The usual sign is early yellowing or fading between the leaf veins. Interveinal means the area between the veins.

Q: Why can heavy flowering feeds cause a shortfall?
A: High potassium levels in bloom boosters can interfere with magnesium uptake, so growers using them watch magnesium closely.

Q: How large is the container?
A: It holds 2.5 Gal and measures 7 x 9 x 14 in. It ships at 25 lb.
