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.

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.

    Très beau résultat! Pour ma première expérience et en extérieur je dois dire que l’efficacité des produits reefertilizer sont à leurs combles! Commande reçu à temps mes plants en avait besoin! Je ne savais pas où me tourner c’était ma première fois avec les engrais et je recommande Reefertilizer!

    This is my first plant I ordered Reefertilizer to help with the grow so far I am happy with the results my plant seems to be weeks ahead of all my friends plants as far as budding. I can’t speak on the final product yet but am exited to. One of the best things about this product is the support they offer with it they check up and have answered any questions I’ve had through this process. Great product great company keep it up.

    Ok so I’ve decided to give this stuff a go. I had a friend put a Fruity Pebble’s OG in his backyard for me, and he knows nothing about growing. Needed a simple way to get the nutrients into the plant, so I ordered the Grow and Bloom. Unfortunately he had to move so I took it back home and put her on the back balcony. Side by side to the other girl I had out there, well the one I was giving Floranova compared to the one getting Reefertilizer witch is 6 weeks younger, but 3 feet taller and 4x thicker stem at the bottom. On my indoor girls, it is the best nutrients and easiest I ever tried. Will update with pictures soon. First picture is the outdoor and the other one is the indoor. Picture 3 is a Fruity Pebble’s 2.0 and the 4th is a Blueberry AK-47.

    Excellent product. As soon as the flowers started to appear I began using the bloom. Good looking tops with lots of crystal forming.
