Frequently asked
- What pH and EC do most hydroponic plants need?
- Most crops grow best at pH 5.5–6.5. EC varies by crop: leafy greens such as lettuce sit at 0.8–1.2 mS/cm, while fruiting crops run higher. Each plant profile lists its own range.
- What is the easiest plant to grow hydroponically?
- Lettuce. It reaches harvest 28–35 days from transplant, tolerates beginner mistakes, and grows in deep water culture, NFT or the Kratky method.
- How do I use these plant profiles?
- Open a plant to get its pH, EC, light (DLI) and temperature targets, the systems it suits, and the days to harvest, then set your reservoir to those values.
