Humboldt County's Own Magnum - Magnesium/Sulfur Supplement with Vitamin B1 - 32 oz

Magnesium Support for Flowering Crops - 32 oz Bottle

Magnesium deficiency can slow growth and cut yields, and yellowing leaves often mean it has already affected development. This magnesium/sulfur supplement with vitamin B1 supplies magnesium, the element at the center of the chlorophyll molecule, so plants can keep producing the sugars that drive growth. The vitamin B1 helps plants cope with the stress of demanding flowering regimens.

The 32 oz bottle suits growers who want a dedicated magnesium supplement on the shelf. It works for home gardeners running a regular indoor cycle as well as for small commercial rooms that dose often. Each bottle is sold individually.

Key Features & Benefits

• Magnesium/sulfur formula — supports chlorophyll production and steady growth.
• Vitamin B1 included — helps plants handle the stress of high-performance flowering regimens.
• Base nutrient compatibility — works well with all popular base nutrients, so it fits your existing feed program.
• 32 oz bottle — a practical size for repeated dosing across several cycles.

Who Should Use Humboldt County's Own Magnum

Growers running hydroponic systems or heavy-feeding flowering cycles can use it. It also suits anyone whose base nutrients are low in magnesium or whose bloom boosters are high in potassium, a common cause of magnesium shortfalls.
