What nutrients do I need for hydroponics?
You need a base nutrient with NPK (nitrogen, phosphorus, potassium) plus micronutrients. For herbs and leafy greens, a single-part nutrient works fine. For fruiting plants, get a 2-part or 3-part system with separate grow and bloom formulas.
Are hydroponic nutrients expensive?
Not really. A quart bottle of quality nutrients ($15-30) lasts 3-6 months for a small home setup. Powder nutrients are even cheaper. Much cheaper than buying fresh herbs at the grocery store.
Can I use general plant food for hydroponics?
No, standard plant fertilizers lack essential micronutrients and are not pH-buffered for hydroponic systems. Hydroponic nutrients are specifically formulated for soilless growing and dissolve completely without leaving residue.
