Just like people, plants benefit from an appropriate diet. But different types of plants have significantly different nutrient needs, and these needs change during each growth cycle. So what's the best way to keep your fruits, vegetables and flowers happy and healthy?

At General Hydroponics, we wrestled with that question four decades ago. Our solution: Flora Series. First formulated in 1976, Flora Series is the original three-part hydroponic-based nutrient system. And thanks to its ingredients, consistent performance and unparalleled results, it's the most-used nutrient today.

Good Things Come in Threes

Flora Series consists of three highly concentrated liquid nutrients:

  • FloraGro builds strong roots during a plant's vegetative stage.
  • FloraMicro is used during a plant's growth and bloom cycles.
  • FloraBloom is added while a plant is fruiting and/or flowering.

By using different combinations of these products, you can fulfill each plant's exact nutrient needs based on its growth stage and environment. Your plants will receive the ideal balance of primary, secondary and micronutrients — and the results will show. Get ready for vigorous plants, large flowers, enhanced yields and nutrient-dense crops.

Flora Series is a favorite among millions of growers, gardeners, scientists and researchers worldwide. See why for yourself.

For hard water with a ppm value above 250 we recommend FloraMicro Hardwater.
