Recommended for use with Hard Water over 200 ppm
Water quality is a big concern when growing hydroponically. To obtain optimum results, it is recommended to use water that contains as little salts as possible. Unfortunately, this is not an option for everyone and some are forced to grow using water with a high mineral content. In most cases, problems in water quality arise from higher rates of Calcium (although it’s advisable to do a water test to be certain), and using regular Holland Secret Micro will push Calcium levels too high which increase the chances of having a lockout with the Phosphorus contained in Holland Secret Grow and Bloom.
For those who do not want to spend money on a lab test, it is advisable to monitor water quality using a nutrient meter. At levels between 200 and 300 PPM it is advisable to use Hard Water Micro, together with Calnesium to balance out Calcium levels. Any tap water over 350 PPM should only use Hard Water Micro without Calnesium.
Holland Secret is a complete 3-Part Fertilizer with all of the essential elements and trace minerals that a plant needs. It can be used with any grow medium, (soil, coco or hydro) in any situation (cuttings, vegetative, flowering).
Our product is always sediment and urea free and pH buffered for ease of use. With Holland Secret, additives are used only to tweak and maximize performance. Best of all Holland Secret really works!
It is perfect for experts or novice growers as there is no need for individual fertilizers, because the three bottles, have a formula for all situations. Growers will experience no deficiencies when using Holland Secret alone. Without additives, many fertilizers on the market are not quite complete and when used in isolation can be found lacking, creating plant deficiencies.
- Automatically buffers pH to acceptable levels for plant growth.
- 100% sediment free (ie. no precipitation of nutrient salts out of solution and becoming unavailable to plants).
- Works well for novices and experts alike, because as well as being very easy to use. The three part formula gives precise control over feeding schedules.
- Extremely low salt index and only the finest raw materials used. Change the ratio between the three bottles to control nutrition for each specific stage of plant growth, as a professional grower would do.
- It can be used stand-alone without additives as a complete feed program.
**Holland Secret Grow, Micro and Bloom are designed to be used in conjunction with one another, and never as stand alone nutrients.

QUESTIONS & ANSWERSAsk a Question
I have the veg, micro, bloom. Should I use additional cal-mag or will I be ok with just the veg, micro, bloom?
Hello Neil, thanks for the inquiry.
I would say its not nessecary unless you notice your plants are light green in color or show signs of lacking some calnesium or magnesium.
Typically during early flower you could add more Cal-Mag.
Hopefully this answers your question, please let us know if you have any other questions.
Monthly water quality report states that the calcium hardness at a monthly average of 118mg/Lt., reading @160ppm. If I am having Cal/Mag problems can I mix Micro and Micro for hard water together to see if this helps. Thanks, Ed.
If I understand correctly you would like to supplement your current Micro with additional HW Micro. While this would likely take care of any low calcium problems it could cause other problems with too many other nutrients, for example too much Nitrogen. It could also push the TDS too high depending on the stage of growth. Our recommended remedy is to use Calnesium instead since it was designed specifically for this purpose. The levels of Calcium are higher than HW Micro and the levels of Nitrogen lower.
