Grow More Than Just Weed With Reefertilizer!

Reefertilizer’s nutrient blends for veg and flower work great on a wide variety of plants. What makes it so much better than a general fertilizer is that it changes as your plants grow.

A fruiting tomato plant will need a different balance of nutrients compared to when it’s in veg.

Nutrient rich soil will also be depleted quickly when plants are growing fast.
A new source of nutrients are required and that’s where Reefertilizer comes in!

Reefertilizer Works Great For:

  • Tomatoes
  • Peppers
  • Zucchini and Squash
  • House Plants
  • Much More

Don’t Make The Mistake Of Using Any Old Fertilizer To Grow Your Weed Plants.

Reefertilizer was designed for the specific nutritional needs of cannabis for its various stages of growth. However, that doesn’t mean you can’t use it on other vegetables in your garden.
Reefertilizer does a great job growing tomatoes, peppers, and more!

Our nutrient system also feeds the beneficial bacteria living in your soil and helps build an extensive mycorrhizal network to improve the plant’s ability to absorb water and nutrients.

We are one of the very few feeding systems that take both the soil and the plant into consideration.

  1. This is the easiest and best way to feed your plants, the mixture of chemicals and organic, organisms and bacteria to take care of your babies the right way , easy mixing ,easy measuring and dosage to give your plants just the right nutrients at the right time to produce amazing results
    The plants I have added have three to four more weeks of flowering yet but they look and smell amazing I started her flowering at just 6+ weeks of veg you can keep them small and start flowering with photo period strains depending upon how much room you have happy growing ?

  2. Best stuff I ever used. These nutrients kept my plant alive and no yellow leaves at harvest time even after flushing with water only for the last two weeks. My buds were nice and big and firm and smelled great too. I credit my grow to the nutrients from this website REEFERTILIZER and will be using these nutrients for as long as I’m around lol and their around as well. Now I’m smoking the finished product and the smell and flavor of the buds are spot on I highly recommend these nutrients they are safe and do the job they are supposed to and easy to use as well.
    Thanks Guys

  3. This was my second season growing with Reefertilizer Grow and Bloom. Last year’s yield was outstanding and this year’s was even better. It’s a perfect combo for a small crops (I do 8 plants grown outdoors in 5 gallon pots). Can’t wait for spring!!

  4. I have used many other awesome products however, Reefertilizer this 3 step feeding program is in a class of its own, is an absolute fail proof product… any experience level can grow amazing cannabis with ease if this is your absolute first time or you’re 100th successful time. Not to mention the customer service and the information available on how to use these products is second to none. This is an absolute must have in your growing arsenal. I can’t stress enough, it takes out all the guess work of having measuring nutrients like Cal mag, pk ,adding stackers or extra soil amendments it’s all right there in this 1-seed-2-veg-3-bloom-step program.. there’s the starter which is absolutely excellent for starting seedlings/clones and young plants and then for the veg stage there’s a veg fertilizer that does exactly what it’s supposed to do and grows amazing healthy plants and prepares them for the flowering and guess what when they get there there’s a bloom product.

    Don’t take my word or anybody elses let reefertilizer 3 step speak for itself!

  5. Very satisfied. Looking forward to getting the whole system for next spring

Q & A

Hi guys I will be using your product for the first time this year for my outdoor grow. I will be using 10 gallon fiber pots what amount of water do you recommend per plant for a proper soak Jd Georgeoff asked on April 1, 2023

Hey JD, It would depend the soil and how much water it can hold. My guess would be about 3 gallons, but you would want to add enough that there's runoff out the bottom of the planter.

Is reefertilizer necessary with organic soil? Tim asked on February 17, 2023

The nutrients in organic soil need time to break down, in some cases this may leave your plants needing additional nutrients in a hurry. This is where Reefertilizer Grow and Bloom come in to provide a blend of nutrients that are immediately available to your plants.

What is the best soil to use with refertilizer? Don asked on January 16, 2023

Hello Don,
Most potting soils from the garden center will work. For example, Pro Mix HP is a popular one folks like to use for cannabis.
