Want to simplify your grow and save money?

Then you need, Surge Plus, the 7 in 1 additive that basically takes seven separate plant nutrients and combines them into one powerful mix which means less nutrients to buy and mix on your end.

This plant additive combines the power of sea kelp, amino acids, molasses, carbohydrates, humic acid, fulvic acid and vitamin B1, to elevate your plants to the next level.

If you're looking for the best plant nutrients then look no further, Surge Plus is your one stop shop to meet all your needs.


Vitamin B1 has been shown to significantly increase crop yields and encourage healthy and vigorous growth. B1 also assists the plant in rooting, growing, and flowering which helps to keep plants stress free!

Humic acid chelates nutrients like magnesium, calcium, and iron by providing natural carrier compounds to bring growth enhancing nutrients and vitamins to your plant. Humic acid stimulates root and enzymatic function and assists in the more efficient utilization of nutrients and vitamins.

Surge Plus is also enriched with sea kelp which is renowned for its many benefits, including stress relief and increased amino acid and protein activity. Amino acids are the base components of protein. Supplementing with them will allow the plant to bypass their synthesis and put those resources elsewhere. Surge Plus has added amino acids to help your plant to create energy and transport nutrients. Amino acids help to increase chlorophyll production and are a source of nitrogen the plant can easily take in. Extra carbohydrates provide an energy boost to your plant during flowering to enhance yields.

Molasses helps to feed the microorganisms living in your soil by providing key minerals and vitamins. Molasses has numerous benefits for your soil like preventing salt build-up and nutrient deficiencies!

Fulvic Acid is invaluable because it binds metallic based nutrients and helps them enter the root system. Basically, it speeds up getting nutrients to your plants, which in turn creates numerous benefits such as growth and faster recovery for underwatered plants.

Ask a Question
  • Does this take place of ..super b carbo etc. If a person is changing to powder .from liquid schedule ..

    Hi Mike,

    Yes, in a powder feed schedule Surge Plus can take the place of many of these nutrients as it has Vitamin B1, humic acid, etc, all combined.

    One thing though, for the flowerings stage we would recommend using Carbo Blast with Surge Plus, to really get those crystals/trichomes.

    Here's a link to a powder feed schedule if you have any questions regarding amount to use: FHD-Powder-Schedule-2021-grams (

    You can also check our downloads page for more info on feed schedules: DOWNLOADS | Future Harvest

  • Is this a nutrient that will take care of everything or just additive to enhance with other nutrients

    Surge Plus is a combination of 7 popular additives on the market to enhance the growth of your plant. You would still need to use a base nutrient with this product.

  • Do you add this to your regular nutrients mix for soil or separate

    Surge Plus can be mixed in with your regular nutrients. Allow for proper mixing time between adding nutrients.

  • This mentions for use with "soilless growing mediums." Does that include hydropnic? I already run your full line of products so I dont even know if this will do much more than what I am already achieving. I run hydroponic only . Thanks.

    We don't recommend Surge Plus for use with hydroponics.

  • DWC / hydroponics not recommended why? Is it the feed water water cycle for soil Making it to concentrated Or it doesn't uptake well Wanna know just purchased it

    Hi London,

    Great question, while Surge Plus is possible for use with hydroponics, we don’t recommend it as it could result in clogging of your system and excess cleaning, since it is a powder additive.

    Plus, Surge Plus contains Humic Acid which is recommended for use only in soil and coco as it takes time to break down to become bioavailable to the plant.

    Thanks for the question and have a great day!
