I just finished re-reading half a dozen SCROG tutorials and Im still confused about when to induce flowering. Most of them seem to say to switch to 12/12 light cycle as soon as the plants get up to the bottom of the screen - BUT - then several of them also talk about extending veg time to fill in the screen???
I have a 2x3 tent (7 sq ft) with 4 plants - 2ea Northern Lights and 2ea CBD Critical - all feminized. All are in 5 gal fabric pots, in soil. I just finished installing a new LED light that is much better than my CFL's I started with.
The screen is set 8" above the dirt.
These plants are all about 5-6 weeks old now. One is quite a bit bigger and more vigorous than the others and one is lagging behind the others, so I have one big, 2 medium and one runt.
The runt is still 2 to 3 inches below the screen, then next one is through maybe 1", then the 3rd one is up to 3" taller and the big brother would be 4 to 5" if I wasnt training it flat along the screen.
I have been doing some FIMing and topping, so all of the plants have 6 to 8 stems. Some of those stems are quite a bit behind the others and still have a long way to go to reach the screen. I am tempted to prune those but not sure. I have been lolly popping for the last 2 weeks off and on, but there is still a ton of stuff below the screen.
Should I trim the slower branches now or wait and see how they do?
Should I start 12/12 now or wait for things to fill in more?
Here are some pics.
