Vegetative Growth

Veg length sets your plant count, canopy shape, and yield ceiling. Learn the 2-4 week clone window and how PPFD intensity dictates internode length and node count.

Veg length and plant density are the same decision viewed two ways. Match veg duration to your canopy strategy — fewer big plants vs a sea of small ones.

Topping, low-stress training, SCROG netting, and defoliation each do a distinct job. Learn what each one changes and the standard commercial recipe that stacks them.

A repeatable, staff-teachable procedure for the pre-flip cleanup that sets up an even, airflow-friendly flower canopy.

The exact climate band that builds a vegetative plant — VPD 0.8-1.1, PPFD 300-600 ramping to 600-900, and the temps and RH that hold it.

Vegetative crop steering in the root zone — lower EC, higher water content, small drybacks, warm roots — with the coco vs rockwool differences spelled out.

When and how to move plants up — triggered by visible roots, not the calendar — with a full SOP and the coco vs rockwool prep differences.

Mainlining builds a hub-and-spoke manifold of identical colas from a single early top, forcing hormonal and hydraulic symmetry the whole plant inherits. Learn the node-count math, the coco vs rockwool recovery differences, and why it trades veg weeks for canopy evenness.

A flat canopy is a measurable target, not a vibe. Learn the height-window rule, the flip-readiness checklist, and why an uneven table wastes photons at the exact PPFD you paid to deliver.

A fast diagnostic playbook for the veg problems that cost you uniformity: stretchy plants, stalled growth, and the mobile-vs-immobile deficiency read — with the coco vs rockwool root causes that differ.

Work backward from fixture footprint and yield target to the exact plant count, container size, and veg length. The per-light math that turns a canopy strategy into a repeatable veg schedule — worked for SOG and SCROG.
