Lettuce Growing Guide
Use the crop’s mature habit, harvest method and local conditions to refine the stored planning values.

How much room does lettuce use?
At the stored 8-inch plant spacing, an 8×4-foot rectangle produces 72 simplified grid positions. A traditional row layout using about 12 inches between rows gives roughly 48 positions in the better orientation. These are geometry checks, not a recommendation to fill every position.
This family includes leafy crops as well as larger perennials. Harvest style and mature head size can change the practical spacing target.
Lettuce Growing Guide-specific
Lettuce Growing Guide-specific planning characteristics
Use the stored 8-inch plant spacing and 12-inch row spacing for lettuce growing guide as geometry inputs, then compare them with the cultivar’s mature habit and your harvest method.
ctical database starting point is about 2 gallons and 6 inches of depth per planting position where individual containers are used. Container shape, cultivar vigor, heat and watering frequency can justify more root volume.
Light and starting method
The reference light requirement is Full sun to part sun, and the usual starting method is Direct sow or transplant. Use local frost timing and the seed packet to decide when that method is appropriate in your climate.
Season timing
The planning maturity range in the database is roughly 30–60 days. Check whether a cultivar’s label counts from sowing or transplanting before using the number to schedule harvests.
