Epic Boost by HY-PRO Fertilizers is a highly concentrated hydroponic flowering booster that supercharges your plants' sugar production to deliver explosive yields and rock-solid, resin-drenched buds. Are you tired of seeing airy, lightweight flowers that lack density and flavor after weeks of hard work in your indoor grow? During the critical flowering phase, plants can deplete essential nutrients in the rhizosphere in less than 72 hours. If they do not get the exact surge of phosphorus and potassium they crave, your harvest will suffer from stunted growth, weak aromas, and disappointing yields that do not reflect your effort. Epic Boost steps in exactly when your crop needs it most. This premium additive floods your system with chelated minerals and superphosphates, instantly accelerating photosynthesis and transforming that energy into massive, heavy, and intensely flavorful buds.

What this bloom booster does for your harvest

Epic Boost is specifically formulated to push your plants to their absolute genetic limits during the second half of the flowering stage. By providing a targeted NPK 1-8-7 ratio, it ensures that your crop has all the necessary energy to multiply cell division and increase resin production.

Whether you are running deep water culture, NFT, or other hydroponic and aeroponic systems, this liquid formula dissolves completely without leaving residues that could clog your drippers or pumps. It is the ultimate tool to turn a good harvest into an epic one, maximizing both the weight and the terpene profile of your flowers.

Key features and benefits in a nutshell

  • NPK 1-8-7 formula: Delivers the perfect spike in phosphorus and potassium, which means your plants can focus entirely on fattening up their buds.
  • Chelated minerals and trace elements: Ensures rapid and complete nutrient absorption, preventing deficiencies and keeping your crop vibrant and healthy.
  • Superphosphates included: Accelerates photosynthesis and sugar production, resulting in noticeably sweeter, denser, and more aromatic flowers.
  • 100% water-soluble liquid: Leaves zero residue in your reservoir, keeping your equipment clean and functioning flawlessly.
  • Highly concentrated (1:1000): You only need 1 ml per liter of water, making it a highly cost-effective addition to your cannabis fertilizers lineup.

How to use it in a few steps

Adding this booster to your feeding schedule is incredibly straightforward. Just follow these simple steps to watch your buds swell:

  1. Wait for the right moment: Start using Epic Boost from the 4th week of the flowering phase.
  2. Shake well: Always give the bottle a good shake before use to ensure the ingredients are perfectly mixed.
  3. Mix the solution: Add 1 ml of Epic Boost per 1 liter of water (1:1000 ratio) to your nutrient reservoir.
  4. Combine with your base: Use it alongside your standard HY-PRO Hydro A+B base nutrients for optimal results.

Frequently Asked Questions

Can I use Epic Boost in soil or coco coir?

This specific formula (Epic Boost Hydro) is optimized for hydroponic setups. While HY-PRO offers specific boosters for other media, using this in hydro ensures the best pH stability and nutrient uptake without clogging your system.

When exactly should I stop using it?

You should use it from the 4th week of bloom right up until your final flush (usually 1-2 weeks before harvest) to ensure the plants consume all the residual nutrients for a cleaner smoke.

Will it alter the pH of my reservoir?

Like most highly concentrated boosters, it may cause slight fluctuations. Always mix your nutrients first, check the pH, and adjust it to the optimal range (5.5 - 6.2 for hydro) before feeding your plants.

Personal Experience of Pevgrow’s CEO (Alan)

When I am running a hydro setup, I do not like to mess around with a dozen different bottles that end up clogging my drippers. That is exactly why Epic Boost has earned a permanent spot in my grow room. It is incredibly clean, mixes instantly, and the 1 ml per liter dosage means a single bottle lasts me multiple runs.

I usually introduce it right around day 25 of flower, and the difference is night and day. Within a week, you can literally see the calyxes swelling and the frost starting to stack up. If you want that dense, commercial-bag-appeal look without overcomplicating your feeding chart, this is the booster you need to get the job done.
