Getting started with hydroponics
Buying guide

Getting started with hydroponics

Choose your crop

Select a system based on what you want to eat. Herb kits are compact for windowsills, while vegetable systems offer more root space for peppers and greens.

Check your space

Measure your vertical clearance. Many systems feature adjustable lights that can extend up to 17.7 in or more to accommodate tall plants.

Monitor the water

Use pH test strips and liquid nutrients to maintain the reservoir. Plants in these systems rely entirely on the water solution for food.

Quick answers

Common questions

What is the difference between DWC and aeroponics?

Deep water culture (DWC) keeps roots submerged in aerated water, while aeroponic systems mist the roots with nutrients.

Do these systems come with seeds?

Most listings include the hardware, pump, and lights, but seeds are usually sold separately.

How often do I need to add plant food?

Most setups require adding A&B nutrient solutions every two weeks when you top off the water tank.

Can I grow large vegetables in a countertop kit?

Small kits are best for herbs and leafy greens, while larger vertical towers or 30 pod systems are better for fruiting vegetables.
