FLORAMICRO HARDWATER: If your tap water is over 200 ppm (or contains Calcium above 70 ppm), use Flora Micro Hard water.

The original Building-Block Nutrient System, often imitated but never duplicated. Flora Series contains complete Primary, Secondary and Micro Nutrients for enhanced yields and better crop quality. Users can adjust mixtures to suit specific plant needs. Flora Series enhances flavor, nutrition, aroma, potency and essential oils in both hydroponic and soil cultivated plants. Flora Series contains highly purified concentrates for maximum solubility and pH balanced for ease of use. Known throughout the world as the industry standard, NASA and Antarctic Research Scientists choose Flora Series because of its superior formulation and reliability. DIRECTIONS FOR USE: Mix 2.5 ml to 10 ml per gallon of water depending on the plant’s growth stage. Note: The proper ratio of each Flora Series nutrient depends on the crop and the stage of growth (look on the label for specific recommendations).

I've been growing for almost 5 yrs now. After my first 2 plants, I found a perfect feeding schedule made for the general hydroponics Flora series w/ Cali-Mag. WOW, after that every single plant I've ever grown since has produced high yields of high quality bud. It definitely is the tried n true nutrient solution that is the only kind I'll use in my hydro growing mediums which I use a mix of: Coco coir, perlite, rock and sand. It hasn't failed me yet!!

I had to keep adjusting the alkaline levels in my hydroponics system by a lot when I added water, and was not aware that there was a 'hard water' version of this product. I used it right away, and having used it the last 2 times in my system, I have not had to adjust my alkaline levels!! I will buy this from now on!

This nutrient is absolutely wonderful if you have hard water. Even the build-up in the containers is considerably less. The plants also seem to be using the other nutrients more efficiently as well. I would highly recommend this to anyone growing indoor plants.

It is very good for your plants. But after the cell is removed from the top of the bottle is pours everywhere because it was not done wright.

All general hydroponics products work great. All my plants look really healthy including some that were struggling before i used this.

I use this fertilizer for more than a year for greens, tomatoes and peppers. Works very good and provides all needed nutrients.

I’ve been using these nutes for years with great results. Added the hard water to the mix due to extremely hard well water.
