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.

Key Features:

  • 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.







Ask a Question
  • Is the system a daily or weekly feeding

    It is a daily feeding. But we recommend flushing with straight pHed water every third feeding.

  • I have seeing that are 3 weeks old, but I just bought the 3 part system today. Should I start with week 1 measurements, or should I jump straight to week 3?

    Hello, thanks for reaching out.
    I would start with a half strength week 1 feeding to ease your plants into the nutrients.
    Acouple feedings at half strength is safe, then feel free to bump the ratio up to the recommened dosages.

    If you have any more questions please feel free to ask.

  • Is it wise to mix a big batch for future watering

    You could mix a batch for future watering no problem, I wouldn't leave it longer then 2 weeks.
    It would be best if you had an air stone or some sort of device agitating the water aswell.

    To be extra safe I would check the pH of the solution before using it.

    Best regards

  • looking on your analaysis page, why are so any ellements not listed and all show same ellements in 3 diff parts of foods, and why do all your foods have added pesticides listed.

    Hey, great quesitons.
    A lot of the information that we put out has regulatory agencies in mind.  One of the problems we are faced with is that some of the nutrients we have in our products fall under the minimum amounts permitted by these agencies. 


    As for the pesticides, these are maybe relevant for many of our customers but are for the large licensed producers that we serve.   The pesticides listed are the 96 specific ones that Health Canada tests for in Cannabis and these types of customers feel more assured that their end product will be free of these if we test for them.

  • Will the nutrients be effective if they got cold enough to be slush consistency but not frozen solid.

    Hey Carson, thanks for reaching out. I had just talked to our Biochemist, he had said the nutrients should be fine. However if you want to pour some into a clear container and notice any crystallization It would suggest some of the nutrients salts have fallen out and wouldn’t be good to use. If you have any other questions please let us know Best regards and happy growing -Jesse

  • When mixing up nutrients it’s says allow additional mixing times between each additional product I’ve been giving about ten minutes is this too long or not long enough Thank you My plants are thriving using your products

    Hello George, thanks for choosing Future Harvest Nutrients. 
    I am glad to hear your plants are thriving with our product line!

    It is important to mix up the Micro before the other additives go into the water reservoir.
    I would recommond waiting atleast 2 minutes if you are mixing it well, then adding additional product.

    Hope this helps, if you have any other questions feel free to message on us here
    Thanks & happy growing 

  • Do I need to flush plants using this product? Or can I continue to use all through the flower development?

    As a rule of thumb, we always advise our users to flush your medium with pH adjusted water every 3rd watering. Advanced growers will use other techniques to monitor nutrient levels in their medium to dictate when to do a water flush to lower the levels back to optimum range.

  • What is the shelf life of your Holland Secret ? How do I know if it has expired and is no longer serving it’s purpose ?

    Generally, all liquid fertilizers have an expiry of around 8-10 years depending on the conditions of storage. Also, fertilizers degrade over time so using a bottle that is 7 years old is less effective than a bottle that is 2 years old. We recommend our customers to use up their product within the first 2 years to get the best results. I've never personally seen a bottle that is 8-10 years old but I've been told you will notice some crystallization in older product. 

  • Are your nutrients going to need anything else if I use ro water for my special ‘’tobacco ‘’

    No, you do not need anything else! Our nutrients is all you need to add to your RO water to get your "tobacco" going!
