I think the twins were less than 6 weeks old from seed. Did not LST. Used CFL's close to the plants so they grew short and wide. I only trimmed about 3inches off the top of the twins cause they are older and taller than the others.

My room is full of bugs, but I haven't noticed any problems. I've read that 2 tablespoons of salt and one Gallon of water acts as a pesticide against spider mites. Use a sprayer.
