Description

Build the vegetative structure a big flowering plant needs later

Grow Big is FoxFarm's nitrogen-led liquid concentrate for the vegetative stage, formulated to drive the kind of growth that pays off once a plant switches to flower - thick stems, dense foliage and enough branching to carry a heavy finish. Alongside its core NPK ratio it carries earthworm castings and Norwegian kelp, the combination FoxFarm credits for sturdier, healthier growth rather than fast, leggy stretch.

The vegetative stage sets a plant's eventual ceiling - a thin structure here limits how much weight it can carry once flowering begins, whatever the bloom feed does later. Grow Big is designed to be pushed hard through this stage, building the branching and canopy structure that a phosphorus-led flowering feed needs something substantial to work with.

It is used from early vegetative growth through the switch to flower, kept stable in solution at a controlled pH, then tapered off in favour of Tiger Bloom and Big Bloom. It also works as a supplemental foliar feed at a reduced rate, sprayed on both sides of the leaf away from direct light.
