Flowers growing in hydroponic towers

Most types of flowers can be grown hydroponically. Essentially the elements that they would typically get from the earth and sun can be replaced in an indoor farm or a home system like the ZipGarden. There are no seasons with indoor hydroponics, so you can enjoy a bounty of blossoms all year long. It’s a great way to brighten winter days or kick-start your spring season. LED lights replicate sun-shiny days, and the perfect dose of nutrients will give you the best buds, blooms, and abundant crops. Many flowers are edible, too, so you can munch away on them with your leafy greens and hydroponic herb bounties.

It’s been flower power in the ZipGrow Towers at the research ZipFarm this winter.

They have successfully trialed these flowers at a range of 1.4 EC and 6.2 pH.

Zinnia Elegans - Zinnias
Native to Mexico, Zinna Elegans have solitary flower heads about 5 cm across. There are also giant forms with flower heads up to 15 cm in diameter. 

The flower colors range from white and cream to pinks, reds, and purples, to green, yellow, apricot, orange, salmon, and bronze. Some are striped, speckled, or bicolored. There are 20 species and more than 100 cultivars of zinnia.

A common threat to these flowers is Powdery mildew, so be sure to check for signs and take steps to control this.

Zinnia’s are like a gift that keeps on giving; the more you cut them, the more they return. They are fast-growing, especially with hydroponics, so they make an excellent starter flower for newbies.

Digitails Purpurea- Foxglove
These gorgeous elongated clusters of flowers are in the plantain family Plantaginaceae, but don’t let their beauty deceive you. The entire plant is poisonous to humans and some animals and can be fatal if ingested due to the presence of the cardiac glycoside digitoxin. We don’t recommend these if you are growing at home and have pets or young children.

They bloom in four key color types; a white flower with purple spots; an albino flower with yellow spots; a light purple flower, and a dark purple flower.

Foxgloves are tall and can produce up to 75 flowers, releasing up to two million seeds. They grow quickly from seed, so you can transplant them to your hydroponic Towers in no time. For continuous bloom, cut the flower spikes back when 3/4 of the blooms have faded. Cutting off the tops of the spikes can encourage new flushes of growth.
