Ive got a 12/12 grow from seed, in a very very small space, (11 inches high ). My questions are. Should i still top this plant? Or just grow one large bud? and what if it outgrows the box? I guess i could put the 2 lights on the sides, but, it would hit the roof pretty soon.

11 inches is not alot to mess with.

As such you have a few options. You could top the plant, restricting vertical growth and allowing to bush out, you can train the plant to grow horizontally as much as possible, or you can squeeze the stem using the super cropping technique to bend over the main kola and trian horizontally along the wall.

For your next grow you could consider using a dwarf auto flowering strain such as Lowryder 2 - would be pretty much perfect for your situation.

Good luck.

Its not really my grow. Its a situation I'm in for a bet. I would never really attempt a grow like this . Im just wondering, about topping, because I'm starting in flowering straight away. So, do i just do it under the second real node?

for a bet? haha............"aint gotta lie to kick it!"

Hah. I see how it looks. Arguing is effort. Any information on topping in my situation?
