so i started germinating the Sunday before last, its been about 4 days since ive seen the sprouts, i have been giving them light 18/6 since they sprouted. i failed to get a timer yet due to being poor... so today i left the plants on for about 24 hours... i just shut the lights off i plan to switch em on in about 13 hours or so... is this wise or what should i do.. i dont want to mess things up even though they are young.. i want it to be healthy.. advice??
