Powder Cannabis Fertilizers for Veg & Flower

Vegetative plants and flowering plants have very different nutritional needs. While a plant is growing, it requires plenty of nitrogen. Nitrogen helps with the growth of new stems and leaves. This results in a bushy plant that can efficiently metabolize UV rays. Our Grow fertilizer is formulated to give your plants the nitrogen required, as well as various micro nutrients proven to aid cannabis growth.

Flowering cannabis plants are no longer focusing on overall growth, it is now putting energy into developing flowers. These flowers will eventually turn into buds, so a steady diet of nutrients is necessary. Phosphorus, potassium, magnesium, and calcium are the heavy hitters at this stage of growth. Having ample amounts of each will result in large dense buds with an amazing aroma. A lot of commercial fertilizers accomplish this with several products, we like to do it with one.

Crafted to Grow Good Weed Easy

Our Grow and Bloom cannabis fertilizers were designed to make growing cannabis fun and easy. No more mixing several liquids together and no more paying for water. Powder cannabis nutrients make it easier to measure correct nutrient concentrations. Grow and Bloom can be used with additional nutrients like “cal-mag” if required but provide the baseline nutrients to support a plant from seed to harvest. Powder nutrients are also easy to flush in case you run into over fertilization problems.

Feed your cannabis plants in 3 quick steps

One

Add powder to 250ml of warm water.

Powder cannabis fertilizer step 1

Two

Mix until dissolved.

Powder cannabis fertilizer step 2 mix until dissolved

Step Three

Mix solution into water for feeding or resevoir. 

Feed your plants once a week.

Veg Phase

Start feeding your plants Reefertilizer Grow when the plant has 3-4 sets of leaves.

Veg Week 1 1 scoop mixed into 4L of water
Veg Week 2 2 scoops mixed into 4L of water
Veg Week 3 3 scoops mixed into 4L of water
Additional Veg Weeks 3 scoops mixed into 4L of water

Flower Phase

Start feeding your plants Reefertilizer Bloom when you switch lights to 12/12 or when preflowers appear.

Flower Weeks 1-3 1 scoop mixed into 4L of water
Flower Weeks 4-8 2 scoops mixed into 4L of water
Additional Flower Weeks 2 scoops mixed into 4L of water
1-2 weeks before harvest Flush plants with plain water

Cannabis Nutrient Requirements From Seed to Flower

A recipe for faster cannabis growth

Reefertilizer Grow contains the essential nutrients required to establish strong stems, good leaf structure, and a healthy root system. Our fertilizer are synthetic which allows them to be metabolized much faster than organic blends. Essential elements are available for the plant as well as the living microbes in your soil.
Plenty of Nitrogen is required for the plant to develop leaves and thick stems. Micro nutrients will help fuel many cell functions crucial to photosynthesis and cellular replication.

Crafted for flowering cannabis plants

When cannabis plants begin to flower, their nutrient requirements change. Early on in flower, the plant will use its stored nitrogen for a quick growth spurt. After this growth spurt, your cannabis plants will need nutrients used for bud/flower production.
Reefertilizer Bloom provides a higher ratio of phosphorus as well as calcium and magnesium. These three elements are proven to increase bud size and help terpene production.

I start my plants indoors around the last 2wks of March, by the time May 24 weekend comes my plants are already almost 2'tall. Love the fertilizer, the photo of my plants does them no justice and this photo is earlier. I cloned for the first time this year, I cut them May 27/21. They are about 3'tall, and I had to wait 2 to 3 wks for roots to form, so I am still impressed with your fertilizer. My 3 main plants ( the mothers) They reached close to 6' tall in the pots. Topped them 2x this this year. Humidity and Heat in Ontario this year was really bad, water issues, white mold, catapilers this year didn't have last year. But still trying to keep them going, they are root bound so watering is harder now. My plants end early because I start them early, I get to miss more rain and problems that come in the end of September and October. If you haven't tried Reefertilizer yet, you don't know what your missing. Try it. This is only my 2nd year growing and everyone is amazed and so impressed with my plants, as well as me, good luck to everyone, high52all.

First time grower. I'm using a tent with Promix HP. I am growing both photo and auto plants and both are healthy and thriving. My photo has recently started flowering and I moved to the Bloom immediate effect. My buddy next door had a few outdoor plants and was complaining about spots and such on his leaves. I let use the Grow stuff and the effects were immediate with most of the abnormalities disappearing along with a dramatic growth spurt. The price is great considering how little (3 tsp/4l) is required for a once a week feeding.

I finally grew plants to be proud of! Super easy feed schedule with the right balance of nutrients. You can't screw up. Here are my AK47 auto flowers at 13 weeks. I grew them in pro mix, which is a pretty neutral grow medium. I snuck in a couple extra bloom feeds with great success.

Very happy so far! I started using the nutrients on June 18th and my tallest plant was about 18". Its Aug and my tallest are now over 72"! I really found the plants produced alot more consistent/ hearty branches after starting the system. I've got a few on the Bloom now and are stacking up nicely! Happy growing!

Very happy with the product so far ... First time using powder nutrients and haven't had a chance to use the bloom nutes yet. The grow nutes however have noticeably been very well received by the plants and have no issues with nutrient burn. Will definitely purchase again!
