Get Your Bloom On with These Incredible Nutrients

It’s almost time to start transitioning your plants to the flowering phase, and that means a shift in their nutritional needs. While plants in the vegetative stage require a lot of nitrogen and moderate potassium and phosphorus, plants that have started to bloom require less nitrogen and more phosphorus and potassium to support flower and fruit development. 

It’s best practice to pivot your feeding schedule along with your plants’ changing needs, which is why we’ve collected an assortment of bloom-boosting fertilizers and supplements to supercharge your plants and ensure a successful flowering stage and an awesome harvest. 

Bloom nutrients, like flowers, come in many shapes and sizes. At GardenTap, we only suggest the very best products that we love to use ourselves! 

Take a look at our favorite Bloom Boosting nutrients:

Green Planet Nutrients

Massive Bloom

Massive Bloom is designed to promote, well, MASSIVE blooms! Its unique vitamin formula is blended with carbohydrates, a chelated mineral profile, and key nutrients, all of which work together to create the foundation for flowers, buds, and blooms you’ll be proud of. 

Liquid Weight

When you want spectacular flowers and buds, it’s important to remember that plants expend a lot of energy producing floral sites and fruiting bodies. That’s where Liquid Weight comes in, giving your plants and beneficial microbes in the soil a carbohydrate food source that results in larger, high-quality yields

Karbo Boost

Your plants work hard when flowering and fruiting and they need the extra energy that comes from Karbo Boost. This special formulation uses naturally occurring carbohydrates to enhance microbes in the soil and provide sugars normally produced through photosynthesis to the plant directly during flowering. Less work for your plants, so they can focus on producing quality flowers and yields.


Your plants need an energy boost to produce the larger buds and flowers you’re looking for, and Horti-rawK is a one-of-a-kind additive. It provides a large potassium dose, resulting in stronger, healthier plants that will support heavy fruiting and flowering. Your plants will look like they’ve been in their own weight training program.


If aromatic flowers and full-flavored fruits are your growing goal, Rezin amplifies natural processes and increases essential oil and resin production in your plants. Yummmm. Used during the transition and flowering phases, it helps convert nitrates into nitrogen and amino acids to strengthen roots and reduce plant stress.
