Lights on a 18 to 6. All 5 plants started the exact same method. The bigger one and the seedling are just a little side project out of seeds from a bag. However what is funny. Or not so funny. Is that the seeds I spent good money on are the three middle sized plants that are starting very slow and have already lost a leaf on two. The bag seed one has thrived and grown to perfection in a short amount of time. Oh well. Maybe they will catch up in the long on. Or at the very least produce good quality buds.
