Hydroponics

Hydroponics - DWC roots

Have you ever wondered how plants get their nutrients?

Most plants absorb what they need from soil—but they can grow just as well, and sometimes even better, in water.

That’s the idea behind hydroponics, a gardening method where plants are grown in a nutrient-rich solution instead of soil.

Hydroponic systems make it possible to grow fresh greens, herbs, and vegetables in places where soil isn’t practical—small apartments, basements, urban homes, deserts, and even outer space.

Because the water and nutrients are recirculated, hydroponics is also incredibly efficient, using far less water than traditional gardening.

Whether you’re curious about countertop herb systems, want to try DIY hydroponics, or dream of a productive indoor food garden, this category covers everything you need to get started and succeed indoors. 🌿💧

Beginner Tips for Hydroponics

  • 💡 Light matters more than the system. Good LED grow lights often determine success.
  • 🌡 Keep water temperatures stable. Aim for 65–72°F to avoid root issues.
  • 🧪 Monitor pH regularly. Most hydroponic plants prefer a pH of 5.8–6.2.
  • 💧 Start simple. Kratky jars, mason jars, or a small countertop system are great first steps.
  • 🌱 Grow fast crops first. Lettuce, basil, mint, kale, and microgreens establish confidence and momentum.
  • 🛠 Sanitize equipment between grows. Clean setups prevent algae and root diseases.

Hydroponics FAQs

Is hydroponics good for beginners?

Absolutely. Simple systems like Kratky or small countertop units are incredibly beginner-friendly and require minimal equipment.

What plants grow best in hydroponics?

Lettuce, basil, mint, oregano, kale, spinach, chives, and many leafy greens thrive in hydroponic setups. Fruiting plants like tomatoes and peppers also work well with stronger lighting.

Do I need special lights for hydroponics?

Yes, most indoor setups need LED grow lights that provide full-spectrum light similar to sunlight. Without enough light, plants grow slowly and produce fewer leaves.

How often do I change nutrient solution?

Most growers change the nutrient reservoir every 1–2 weeks to keep minerals balanced and prevent buildup.

Is hydroponics expensive?

It can be, but it doesn’t have to be. A basic DIY Kratky setup costs just a few dollars and works great for leafy greens and herbs.
