I was wondering the same thing. And if i only have a 4 foot high box and need to grow short plants with max yeild, how do i go about doing this. Forcing it to flower early? And how do I do that? Sorry for all the dumb newb questions, just trying to fully understand everything as soon as possible, so I can get started on this art.
From my experiences my plants roughly doubled in height after switching them to flowering, but after 2-3 weeks all growth is basically limited to the bud sites.
If you use a 3:1 ratio it will guarantee that you will not run out of room. Otherwise some plants get only a little bit bigger, others double and some can even triple in size. Of course this is highly dependent on the size of pot one uses.
what is a 3:1 ratio? are you talking about the timing scedule? and is that the lighting scedule i need to use to grow the plants small but heavy?
he means that if you give the plants 3 times the space they are taking up before flowering then you'll have no space problems...
im on my first grow, but right now 2 weeks into flowering my bushy indica's have nearly doubled in size--not height, but overall size (thanks to lst). they got like 5 inches higher so far. hope that helps even if only a little.
so here's the answer....Indicas stretch normally about almost twice its vegetative height(end of vegging) sativas normally stretch from 2-2.5x its end of veg. height so its a fact that marijuan will doubles in size once flowering is induced(after the full flowering time of course) hope this helps
I haven't raised my lights more than 2 inches since i started flowering. They are flouros and about 4 inches away.
