Nice Surfbum....
Although the proof won't be visible for another 10 to 12 weeks, i gotta at this stage agree with Swordfish on some form of training....I used to top all the time and grew some big plants. This year I started LST on my plants, and so far I am super impressed with the results...like I say its too early to tell if the yield will be better than my past grows but fingers crossed
I snapped a few stems learning the technique but they all mended with a little electrical tape and some popsicle sticks....some of my girls had 5 to 8 strong leaders...now there is over 30 at least.
My plants were just a little smaller than yours when I started....trimmed a few bottom branches off, got some wire coathangers, and voila....LST is a little high maintenance so far...but will also help to keep the plants more like a spreading juniper than a xmas tree...which certainly helps on the stealth factor come fall....
Next week I will post a few of my hopeful contenders...
