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.
