High Times issue #215 July 1993 had a article by Otis Birdseed "How to yield ten pounds from a single plant." To begin start your seeds indoors mid winter under 24 hours of light. After 3 lower branches have formed the plant may be sexed by taking a cutting off the main stem. Put cut in water under 12/12 light and it will indiacate sex in a week. When the female plant has developed new leaves on the 3 remaning side branches you are ready to begin pinching. After each branch has 3 sets of leaves, pinch the tip off each carefully. Each pinched top should form 2 more leaves, and so on, every 7 to 10 days. When 3 new sets of leaves appear on each branch, pinch again. Train your branches to grow horizontally by bending, tying or weighing them down. The 4 branches become 8, then 16, 32, 64, 128...and so on. After you plant them outdoors in May keep branches tied down or propped up as needed. Most important: if down South, stop pinching the last week of July; if up North, last week in June. It should have thousands of budding sites if you have watered and pinched regularly. It's worked great for me but haven't made the 10 pound yield yet. Almost 6 pounds so far but I keep trying. M Blaze is spot on.
