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.

    Bloom sure helped with bud formation. Bit of time required to dissolve though. My first time growing so nothing to compare with but seems like bloom helped. Thanks.

    This was my first serious attempt at growing and didn’t get a chance to use the grow, as my plants started flowering before I received the order.
    I do feel that the flowering fertilizer helped my small harvest. I am looking forward to ordering the starter kit soon as well as the cloth growing pots and other accessories from y’all. I have learned a ton just from your site and cant wait for spring here in Northern Arizona.
    You guys are top-notch in my book.
    Thank you.

    Made a noticeable difference from last year. Plants were already in the vegetative state so didn’t get to use the starter. It certainly helped with the buds and I’m looking forward to next years results from what I learned on the site. Thanks

    For a first time grower who’s still learning, I think the fertilizers worked pretty well. My buds are nice and big and they look great. I’m just about to harvest some autos I used them on. Excited to get another grow going to use them some more

    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!!
