Salad greens are easy to grow inside as long as their basic care needs are met, such as sufficient sunlight, moist soil, and your growing space isn't too cold or too hot. Use these must-know tips ...
The top side may also be used. On the top side of upside-down planters, lettuce, radishes and cress may be grown, [6] and herbs or flowers such as marigolds can absorb sunlight to decrease desiccation of the planter; that is, preventing drying out. [1] Unsuited are lettuce, peas and carrots as they do not generally do well, grown upside-down. [1]
In biology, the BBCH-scale for leafy vegetables forming heads describes the phenological development of leafy vegetables forming heads, such as cabbage, chinese cabbage, lettuce and endive, using the BBCH-scale. The phenological growth stages and BBCH-identification keys of leafy vegetables forming heads are:
Lettuce grown in indoor vertical farming system. Vertical farming is the practice of growing crops in vertically and horizontally stacked layers. [1] It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. [1]

Within the center of each rotary hydroponic garden can be a high intensity grow light, designed to simulate sunlight, often with the assistance of a mechanized timer. Each day, as the plants rotate, they are periodically watered with a hydroponic growth solution to provide all nutrients necessary for robust growth.
The light from the lamp (1.) functions as a detectable change in the plant's environment. As a result, the plant exhibits a reaction of phototropism--directional growth (2.) toward the light stimulus. Auxin distribution controls phototropism. 1. Sunlight strikes the plant from directly above. Auxin (pink dots) encourages growth straight up. 2 ...
Growing degree days (GDD), also called growing degree units (GDUs), are a heuristic tool in phenology. GDD are a measure of heat accumulation used by horticulturists , gardeners , and farmers to predict plant and animal development rates such as the date that a flower will bloom, an insect will emerge from dormancy, or a crop will reach maturity.
