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.
