  • 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 as a stand-alone without additives or as a complete feed program.



Future Harvest Holland Secret Bloom Guaranteed Analysis

** Holland Secret Grow, Micro and Bloom are designed to be used in conjunction with one another, and never as stand alone nutrients. **

Additional Info

It’s important to use all three parts of the Holland Secret 3-Part plant fertilizer in tandem with one another. Using only one or two parts of the three, like Grow and Bloom without Micro for instance, means your plants will miss out on all the nutrients they need to grow and could potentially put them at risk of deficiencies.

And if you’re looking for more reasons to use the best fertilizer for plants and vegetables here are two. It’s CFIA certified – meaning it meets all the regulatory standards – and it has the added benefit of being able to be used as a foliar spray, so if you want to spray away, you can.

Ask a Question
  • I was wondering when it is best to use the flowering nutes. Is it a week or two Into flower or as soon as i switch lights to flowering?

    You should start using the flowering nutrients (Bud Start, Carbo Blast) week 2 into flower.

  • How often should I use Bloom?

    Please refer to our feed schedules under DOWNLOADS for accurate information (https://futureharvest.com/pages/downloads). You should be using Bloom every feed but feeding frequency will depend on your plant and growing medium. We also recommend a straight water flush every third feeding.

  • If I water my plants every two days , do I have to water my plants with no nutrient s between each feed or I can just water with nutrients every 2 days

    We recommend a straight pH water flush every third feeding! (Regardless of days). Best practice is to monitor your plants and know what is best for them.

  • How much bloom do I use in a 5 gallon bucket

    The ratio changes depending on what medium you're growing in and what cycle your plant is in. Please refer to our DOWNLOADS page for accurate measurements. All measurements are in mL per gallon.

  • Can I use these products outside? Thanks

    Hello Pat, yes you can use our products on crops that are growing outdoors no problem.
    If you have any other questions please feel free to ask.


  • I have mixed up a batch for a water change. And I would like to add more nutrient to raise the ecc a little. Can I just add additional fertilizer one at a time ?

    Hello Shannon.
    Have you been feeding your plants our nutrient line up since the start of their growth?
    You could add additional ferilizers, but you need to be cautious over your pH and PPM meters. 
    Thanks for showing interest in Future Harvest Nutrients.

  • Do I combine measured amounts of all 3 nutrients with 4 litres of water

    As indicated by our feed schedule, one by one, add each measured amount into your water. Remember to always mix Micro and Calnesium first to minimize the calcium falling out.

  • Does this nutrient line contain pgr's?

    No, our nutrient line does not contain PGR's.

  • If I am using dirt to grow my plants are the measurements the same? Thank you
