Green Planet GP3: Micro — 4Ltr

Green Planet GP3: Micro — 4Ltr

GP3: Micro is the constant in Green Planet's 3-part system — while Grow and Bloom ratios shift through the grow cycle, Micro stays consistent, delivering the essential trace elements (iron, manganese, zinc, copper, boron, molybdenum) that plants need at every stage. Without proper micronutrient delivery, even perfect NPK ratios produce deficiency symptoms. Micro ensures the foundations are always covered.

Why growers choose GP3: Micro:

• Complete micronutrient profile — iron, manganese, zinc, copper, boron, molybdenum
• Consistent dosing throughout — same rate from seedling to harvest
• Prevents trace-element deficiencies — the hidden cause of many grow problems
• Chelated minerals for availability — plants can actually uptake what's in the bottle
• Universal media compatibility — soil, coco, hydro, rockwool
• Matched sizing with Grow and Bloom — 1L through 23L

Who it's not for:

Micro is not a standalone nutrient — always use with GP3: Grow and GP3: Bloom. If you're seeing specific micronutrient deficiency symptoms despite using Micro at full dose, the issue is likely pH-related lockout rather than insufficient supply. For CalMag supplementation (calcium and magnesium specifically), add Pro-Cal alongside Micro — they cover different elements. For simpler feeding, Medi-One and Dual Fuel include their own micronutrient profiles.
