edible flowers
Choosing which hydroponic system to use for edible flowers
is largely dependent on the species being grown. Many of the
most commonly used edible flowers produced in hydroponics
are herbs and salad greens, which can easily be grown in nutri-
ent flow technique (NFT) and other solution-culture systems.
Small, compact annuals are also well-suited for NFT, or they
can be grown in substrate-based systems. Larger plants such as
broccoli, squash, artichoke, elderberry, and lavender are more
suited to substrate-filled containers or beds with drip irrigation
due to the extensive nature of their root system.

HARVESTING AND STORAGE
Edible flowers should be harvested early in the day and
only those that are half open or recently fully opened
(species dependent) should be selected. Harvested flowers
should be then placed immediately into a plastic bag and
under refrigeration to prevent excessive moisture loss.
Flowers with long stems can be placed into a jar of water
and kept in a cool place until used. Most edible flowers have
the petals removed before use, and for some, such as mari-
golds and roses, the bitter white base of the petal should be
removed. Edible flowers may be used fresh in salads, salad
