I need to keep them small because my tent is only 2x2x4, I'm afraid if I let them grow naturally it will become to tall for my tent. there's only about 30 inches of room from the top of the pot to the tent roof. I'm using the mars hydro 600w, I lost the owners manual so I'll have to look up the recommended distances, I'm pretty sure it said around 18-24' for veg. Do you suggest me fim, top, or lst with the height issue? Also I'm kind of confused about the nodes, Is the node the new growth that's coming out of side of the stem? If so I think I have 3 of them now. I'll have to do some more research on topping/fim and lst, Is time of the importance right now to preform these things? Or do I still have a week or so to decide. Thanks again for the help to the both of you
