ive been growing weed on my windowcell in four separate med. size pots since the 20th - 1 week/3 days. Two have sprouted and are 4 inches tall and have green, healthy stems. The other two started 4 days later and they havent sprouted. I water once a day and they are under direct sunlight. What would the benefits if any of putting the sprouted pots and/or the unsprouted pots under my 60watt lamp during the nights and moving them back on the windowcell all day???
