I have six @preybird1 Preybird Farms Runtz x Slapz feminized seeds started for a test. Sunday, they were put in water for about eight hours, then Root Riot plugs, in a 10x20 Super Sprouter tray/dome with a diluted Clonex solution in the bottom of the tray. They are under a T5 fluorescent and an inexpensive Famurs 1000w LED at about 40% power for 18/6 period. (I have a germinating/cloning area set in one of my tents.) These will stay under this lighting situation for a week, then have an HLG 100 veg spec swapped with the current LED.
White ‘popped’ in less than a full day and this is how they are as of midday Wednesday.
They are on a heat mat set to 80° F. (The empty 10x20 has some rosin I am warm curing inside it)
Growing journals have been set for them all so everything done can be noted.
