This is a microgrowers dream method. For evidence, observe Haggis' picture of his AK48 plant....about 14" from top to bottom.
The flowering time is unaffected by the light schedule. Every plant has a slightly different gene mix, even within the same strain, so there will be slight variability in flowering times, but that is also true for those who employ a vegetation phase.
Thats one of the things we are hoping to get going with this thread, a "strain report" that will document grows and how they respond to this lighting regimen. I can tell you from experience that Nirvana's Northern Lights stays short and pole shaped when grown this way, and Haggis has his AK48 that seems to show the same.
If you want to read up on this method further, there is another thread that has recently been abandoned, but continued here in a more useful set-up. Here is a link:
Don't post anything in it though, we're trying to move everything over here.
Welcome to you...and come back and visit often.
