Grow + Bloom

Everything for veg and flower.

Two perfectly balanced blends: Grow gives plants in veg the nitrogen they need to build structure, and Bloom switches to phosphorus, potassium, calcium and magnesium for flowers and terpenes.

Mix the powder into water and feed once a week. No complicated instructions or messy liquids.

How to mix and feed your nutrients

1

Measure

Use the scoop in the bag to measure your nutrients for this week.

2

Dissolve

Stir it into a small glass of warm water until dissolved.

3

Feed

Mix into the rest of your water and feed, or add to your reservoir.

Why dry nutrients

Concentrated

A little goes a long way

Much more concentrated than liquids, lighter to ship and easier to store.

Shelf life

Keeps for years

Sealed in a cool, dry place, dry fertilizer keeps its potency almost indefinitely.

Clean

Easy to flush

Chelated nutrients dissolve fully and flush easily if you overfeed.

    Growing good weed should not be hard, I Started out with no Idea what I was doing and immediately got awesome results. I will not ever bother with any other nutrients after comparing my results with everyone I know! And It lasts forever, I am on my 3rd harvest of 4 plants and I have pleanty left! If you are on the fence, get off and grow some awesome weed!

    This is my first time using Reefertilizer in many years of growing and there are as many BEST fertilizer to bye as there are many strains of seeds to buy i have used different types of fertilizer over the years always growing 2 plants so i won’t know until harvest time on a rating i will also (for fun) with my growing friends have a miniature cannabis cup every october and this test will be more accurate. I am a senior and grew up in the 60st. been a judge in2009 cannabis cup and i can prove it. So contact me in October
