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. 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

  2. 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!!

  3. 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!

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.

Can I use Reefertilizer for my vegetables? Emily asked on December 15, 2022

Absolutely it can Emily. Reefertilizer was designed with the right balance of nutrients for cannabis in veg and flower. Many vegetables have similar nutritional needs and Reefertilizer can help grow amazing tomatoes, peppers, and many other consumable plants.
