12 / 12 for my seeds to sprout '^^' after they have...... wich they do.....
i go straight to 16/8 for 6 weeks normaly....
then i go straight to 12/12 for another 8 weeks - 10 weeks.... autotimer.....
Then i usually just water each 3rd day with water then after 4 weeks veg i give them nutes...... Also be aware not to shock your plants with food... 1/4 of the nutes 1s time, 1/2 of nutes second time, 3/4 the third time with 1 time watering in between without nutes..... at about 10 weeks into the grow from seed the plant gets the full nutes + sum extra DWR Nutes ^^
Peace
