Description

Start · Grow · Bloom

The complete feeding system, from seed to harvest.

Three dry nutrients that cover everything a cannabis plant needs — one for the soil, one for vegetative growth and one for flower. No shelf of bottles, no A and B parts: just one clear schedule.

Most three-part kits skip micronutrients like calcium and magnesium and ignore the microbes living in your soil. Reefertilizer feeds both your plants and your soil.

Makes 1,000+ L of nutrient solution

Common questions

The trio feeds up to 8 plants from seed to harvest. Grow and Bloom together mix over 1,000 litres of nutrient solution, and one bag of Start provides 33 applications. Stored cool and dry, the powders keep their potency year after year.

Once a week — some growers split the weekly dose and feed twice. Top up the soil with Start once a month. Follow the feeding chart for amounts.

Mix fresh. Chelated nutrients don’t store well in water for long periods — a few days is fine, but more than a week can lower their effectiveness.

Soil microbes feed on the same elements whether they come from organic or synthetic sources. Avoid over-feeding and keep pH in range. Start’s organic kelp feeds the microbes, and healthy soil means plants absorb more and less ends up in runoff.

    Applied at repotting time in late May, and growing commenced immediately and went great. Added peat moss to my soil mix.I apply the fertilizer once a week as recommended, and, the results have been fantastic. Tons of new growth and bushy healthy plants. All my friends who also are backyard growers, are so jealous

    So far I’ve had some bad luck with my grow and lost a number of plants so the four I have left are still small for this late in season. That being said I’m up to a feeding schedule that uses 15ml for 4 litres of the grow. I’m in a tent in my garage so the season will extend a little and I’m hoping to get into the bloom by end of August early September. My growth with the product so far is okay but I’m new and not sure what to expect. I have not used the start yet (next grow) because the girls were started before it arrived

    Hi guys, thanks for checking in Mike!
    My first time growing on central Vancouver Island. I have to say I’m exceptionally happy with the results “Reefertilizer” has produced to this point! The instructions are well thought out, so are quite easy to follow, even for a stoner like me. I’ve included a pic of Purple Papaya. She’s a very healthy plant, as are her offspring. Again. Thanks guys, for a really great product!!
    PS: Added a link to a some what funny video I posted on YouTube, using your Reefertilizer in a hydroponics solution.: https://youtu.be/Wat5DNIwrT4
    Cheers!
