Description

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.

    Reefertilizer grow has made my plants stronger and healthier than another other supplements I tried. Glad I found this product as its benefits become visably noticable early on!

    I started using Reefertilizer in late spring, harvested early October. I can say without a doubt that my “crop” turned out awesome. Much better than last year!

    Thanks –

    I absolutely love the stuff. It has helped my plants 100%. Before I started using it they were not doing that well after I started they have been just beautiful! I just got done with my first harvest ever and it smells and tastes better than the dispensary down the street.
    I’ll never use another product and will recommend to everyone.

    Verified Buyer (verified owner) –

    My plants were a bad state after we had lot of rain. I thought they were not going to survive. I started using the grow nutrient and they improved, then the bloom nutrient and they survived. The plants were not big, due to their bad start, but they survived.

    Only complaint is how long it takes to dissolve.

    It works great, tried other fertilizers I found to be a lot more hassle for the returns
