Cal-Mag Plus

Botanicare Cal-Mag Plus by Hawthorne Gardening Company is formulated to correct common deficiencies so growers can focus on what makes their grows unique. By helping protect against secondary nutrient deficiencies, this bestselling, professional-grade supplement can help maximize growth in heavily fruiting plants and fast-blooming annuals like cannabis.

Cal-Mag's benefits include: 

• Fully soluble formula that won't clog spray lines or drip emitters
• Easy to use and scalable for small gardens or commercial facilities
• No. 1 bestselling Botanicare supplement
