Supplement lines including FloraKleen, Liquid KoolBloom, Floralicious, and Diamond Nectar round out a complete grow program.

General Hydroponics — Frequently Asked Questions
What is the General Hydroponics Flora Series feeding schedule?
General Hydroponics offers several feeding schedules depending on your goals. Visit our feeding-charts page or pick up a printed chart in-store. We can also walk you through a custom schedule based on your system and strain.
Can I use GH Flora Series in soil?
Yes! General Hydroponics nutrients work in all growing media including coco coir, soil, and soilless mixes. Adjust EC targets slightly lower for soil vs. hydro. Our staff can help you dial in the right ratios.
How does GH Flora Series compare to Athena or Advanced Nutrients?
All three are excellent professional nutrient lines. GH Flora Series is the most time-tested and widely researched. Athena is preferred by many commercial cannabis operators for its consistency. Advanced Nutrients offers a highly chelated "pH Perfect" line. We carry all three and can help you compare.
Do you carry GH Cal-Mag?
Yes, we carry General Hydroponics CALiMAGic and Armor Si (silica) as part of our full GH supplement lineup. These are essential additions to any GH program, especially in RO water or coco coir.
