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.

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.

    I’m so glad I came across this product. I’m new to growing and the 3 step products made it very easy to be successful. There’s a lot to worry about but it’s nice to know I’m feeding my plants properly.

    Two issues- 1) The treatment rate prescribes Weekly nutrient levels with water as usual. But if water in five days then when plants need water or if you get out of sync frustrating. If nutrients used every watering harmful to plants. 2) The Bloom does not dissolve completely like the Grow. Ends up with chunks floating in the bottom of the watering bucket.
    The Start is awesome. Boosts a clone way past anything that I have found.

    I have used many other awesome products however, Reefertilizer this 3 step feeding program is in a class of its own, is an absolute fail proof product… any experience level can grow amazing cannabis with ease if this is your absolute first time or you’re 100th successful time. Not to mention the customer service and the information available on how to use these products is second to none. This is an absolute must have in your growing arsenal. I can’t stress enough, it takes out all the guess work of having measuring nutrients like Cal mag, pk ,adding stackers or extra soil amendments it’s all right there in this 1-seed-2-veg-3-bloom-step program.. there’s the starter which is absolutely excellent for starting seedlings/clones and young plants and then for the veg stage there’s a veg fertilizer that does exactly what it’s supposed to do and grows amazing healthy plants and prepares them for the flowering and guess what when they get there there’s a bloom product.

    Don’t take my word or anybody elses let reefertilizer 3 step speak for itself!
