Pod difficulty: Easy
Growing lettuce in a smart garden
The short version
The default smart-garden crop: fast, compact, and cut-and-come-again — harvest the outer leaves and the head keeps producing for weeks.
Care notes that actually matter
- Harvest outer leaves first; never cut the central growing point and the plant keeps going.
- Looseleaf and butterhead varieties stay pod-sized better than romaine.
- If leaves taste bitter, the plant is running hot or bolting — harvest hard and restart the pod.
Reading the system fit
Lettuce wants about 8 inches of headroom at maturity, which is the first thing we check against every system's clearance. Every system we track clears that bar, so the differences come down to difficulty and attention. It is an easy crop — anywhere it fits, it mostly grows itself.
