Know before you buy
The Flora Series is designed as a complete system, meaning all three components—FloraMicro, FloraGro, and FloraBloom—work together to provide a balanced nutrient profile. You should use them in combination according to the manufacturer's feeding chart to ensure your plants receive the correct ratios for their specific growth stage.
While this system is specifically optimized for hydroponic applications, it can be used in soil or coco-coir. If using in soil, you may need to adjust your feeding schedule and monitor your runoff to prevent nutrient buildup.
You adjust the ratios by following the General Hydroponics feed chart, which specifies different mixing amounts for the vegetative, transition, and flowering phases. Generally, you will increase the FloraBloom ratio while decreasing the FloraGro ratio as your plants begin to flower.
Yes, the Flora Series is a synthetic, mineral-based nutrient system. It is formulated for high precision and rapid uptake in hydroponic environments, rather than relying on organic biological processes.
The longevity of the set depends on the size of your reservoir and the growth stage of your plants, as feeding concentrations vary. For a small-to-medium home hydroponic setup, a 32-ounce set typically lasts through several full growth cycles.
Yes, it is essential to check and adjust the pH of your nutrient solution after mixing. Adding concentrated nutrients will alter the pH of your water, and maintaining the correct range is critical for nutrient absorption in hydroponic systems.
