Granddaddy Purple – Week 1 of Vegetative Stage
With two fully developed nodes and a third beginning to expand, both Granddaddy Purple plants have officially entered early vegetative growth. Each spent about nine days in the seedling stage, and today marks day 11 post-emergence - day 2 of early veg.
Because I’m growing in an inert medium (PRO-Mix HP-CC Mycorrhizae High Porosity), I’ve been feeding with every watering to ensure steady nutrient availability. Water is applied in a ring around each plant to promote lateral root expansion, and I’m maintaining an every-other-day watering schedule.
As of today, GDP1 stands 3.5 inches tall and GDP2 is 3.75 inches tall, both showing strong posture and tight internodal spacing. I’m running 445–460 PPFD (DLI 29–30) with the light positioned 16.25 - 16.5 inches above the canopy to keep the plants compact and structurally sound.
Both plants are responding well to the current environment and light intensity, showing healthy color and even development.
