Growing Poppies Hydroponically

By Jennifer Loucks ; Updated September 21, 2017

Poppy plants are available as an annual or perennial in a variety of sizes and colors. The plants are propagated by planting seeds, which can be grown indoors after collection. The seedlings can be grown in a hydroponics system once they have grown established roots and buds are present. Hydroponically grown poppies can remain growing indoors or transplanted to a flower bed once there is no longer a risk of frost in spring.

Sow seeds in a tray of seed-starting medium six to eight weeks prior to planting the hydroponics system. Cover the tray with clear plastic and place it in a warm location with indirect sunlight.

Thin the seedlings when they reach 1 inch in height by cutting off the competing seedlings at the soil level.

Replant the poppy seedlings into a hydroponics system once the buds have formed. Rinse the seed-starting soil gently from each poppy plant root system prior to planting it in a hydroponics pot.

Pot the seedlings in the hydroponics pot filled with rock wool. The type of pot will vary based on the hydroponics system being used.

Mix the nutrient water at a level of 3 tbsp. fertilizer per 1 gallon of water being used. Connect the hydroponics system and turn on the pump system. Use a liquid fertilizer that is recommended for poppy plants.

Set up the high-pressure sodium light to shine on the poppy plants. This light type works better for poppy plants than a halide lamp.
