Romaine lettuce grows slower than most lettuce varieties, typically requiring about 6 weeks to reach maturity after transplanting the seedlings. However, when grown on an aeroponic tower, you can maximize productivity, achieving up to 52 heads of romaine lettuce in less than one square meter of space. It’s important to sow one seed per growing port to avoid overcrowding, as romaine forms large heads and needs sufficient space for proper development. #romaine #lettuce #farming #gardening #agriculture
