## Understanding Nutrient Systems
One-Part Solutions
Simple and forgiving. A single bottle contains everything plants need. Mix the specified amount per gallon of water and you're done. FloraNova from General Hydroponics is the classic example.
Best for: Complete beginners, leafy greens, herbs, anyone who wants minimal complexity.
Two-Part Solutions (A and B)
The hydroponic standard. Separate bottles prevent certain nutrients from reacting before use. Mix equal parts A and B into your reservoir.
CANNA Aqua Vega exemplifies quality two-part systems. Dutch-formulated specifically for recirculating hydroponics, it delivers professional results with simple mixing. *(Price when reviewed: ~$35 | View on Amazon)*
Three-Part Solutions
Maximum control. Separate Grow, Bloom, and Micro bottles let you adjust ratios for different crops and growth stages.
The General Hydroponics Flora series pioneered this approach. It's become the global standard with decades of proven results. NASA uses it for space station growing, which tells you something about reliability. *(Price when reviewed: ~$40 | View on Amazon)*
