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.

    I start my plants indoors around the last 2wks of March, by the time May 24 weekend comes my plants are already almost 2’tall. Love the fertilizer, the photo of my plants does them no justice and this photo is earlier. I cloned for the first time this year, I cut them May 27/21. They are about 3’tall, and I had to wait 2 to 3 wks for roots to form, so I am still impressed with your fertilizer. My 3 main plants ( the mothers) They reached close to 6′ tall in the pots. Topped them 2x this this year. Humidity and Heat in Ontario this year was really bad, water issues, white mold, catapilers this year didn’t have last year. But still trying to keep them going, they are root bound so watering is harder now. My plants end early because I start them early, I get to miss more rain and problems that come in the end of September and October. If you haven’t tried Reefertilizer yet, you don’t know what your missing. Try it. This is only my 2nd year growing and everyone is amazed and so impressed with my plants, as well as me, good luck to everyone, high52all.

    Bags were too small and if left outside in a covered and dry box;they turned to gell and couldn’t measure accurately.Mixing with hot water was a bit of a pain.
    The product seemed to work well but this year was a better year in weather than most.
