Pot vs Raft: Choosing the Right Container for Hydroponic Success
A pot is a solid-walled vessel that holds growing medium and roots; a raft is a buoyant board with holes that lets plants float directly on nutrient water.
People often picture a “pot” as the default plant home, so when they see a foam board cradling lettuce, they still call it a pot out of habit, blurring the visual and functional lines.
Key Differences
Pots keep roots in substrate like clay pebbles; rafts let roots dangle into the water. Pots suit larger plants; rafts favor quick leafy crops. Drainage is built into pots, while rafts rely on constant water contact.
Which One Should You Choose?
Pick a pot if you want to move plants or use chunky media; choose a raft for fast harvests with minimal setup. Match the container to plant size and how hands-on you want to be.
Can I switch from pot to raft mid-grow?
Yes, but rinse roots gently and let them adapt to open water to avoid shock.
Do rafts need extra aeration?
They benefit from air stones because roots sit in water full-time and need oxygen.
