Keeping the lights at about 30%, 24/7 at this point. They seem to be responding well. Not too much watering. Maybe a misting here or there. Good draining soil. They don't seem to be stretching at all. Growing nice.
Removed a couple of fan leaves from the top in order to expose the new growth and the next day it was as if nothing was removed and everything doubled. They are vigorous growers big eaters and very happy with LST.
The soil I'm using to grow the seedlings in is a mix of mostly FFHF (85.69%), FF CocoLoco (5.257%), Perlite (9.3459%). I threw about a 1/2" of raw perlite in the bottom of each Solo Cup and poked hella-holes in the bottom with an exacto knife and/or a spade drill bit to drain 'em
Only one of the three additional seeds sprouted in the soil. Total of 3 seedlings. Two are developing first real leaves. The third is catching up fast.
Just started a GSC auto and a gelato auto. We'll see if they pop and if I can muscle em through veg into flower while the APEX is in veg for the long haul.
