House & Garden Top Booster 1L – One-Week PK Additive for Enhanced Late-Stage Development

House & Garden Top Booster is a precisely formulated one-week PK additive designed to alter the nutritional ratio of your feed in line with plant demands during the late stages of the growth cycle. By adjusting the phosphorus and potassium balance at the right time, Top Booster encourages more vigorous late-stage development and improved structural integrity.

Unlike straight PK 13/14 products, Top Booster includes additional EDDHA-Fe (chelated iron), improving mineral uptake and supporting overall plant health during this critical phase.

Key Benefits

• Encourages more vigorous late-stage development
• Supports fruit development and structural bulking
• Promotes stem and root expansion
• Improves uptake of other minerals
• Contains EDDHA-Fe (chelated iron) — superior to straight PK 13/14

How to Use

Use for one week only during the late stage of the growth cycle. Follow House & Garden’s feeding schedule for precise dosing guidance. Do not use in combination with other PK additives during the same week.
