Growing a pound+ per/plant isn't difficult. I've done it quite a few times. Then I found that I could grow more, with less risk of a "one-plant-nightmare", if I grew more plants in the same area. Here's the simple recipe for doing so; Use a ebb and flow hydro system that is set up properly in a room that is at least 4 feet by 4 feet in area and at least an 8 foot ceiling. Use GH's 3 part nutes. Use a sexually mature female clone of a plant known for high yields like "Big Bud". Use 5,000 lumens of MH light per square foot of plant area, as close as possible without burning the clone. At 6 inches tall, top the plant. Every third node above that, top each branch again. Use LST to slowly spread the branches in all directions in your grow area until each branch has filled the lateral areas of the entire space to the walls. Then allow the plant to continue growing upwards. This will allow all the side growth to grow upwards also, making a room full of branching. Then, allow the plant to grow in vegetative state until all the branches are between 24 and 36 inches tall. At that height, put the plants into a 14/10 HPS lighting, with the 10 being lights on. Switch the nutrients into a 100% flowering solution. Put a 4 inch mesh screen or net immediately above the plants to support the colas later. Continue the grow, moving and redistributing the branching to even spacing throughout the grow until harvest day. Do not flush, do not stop nutrients, do not change anything or add anything else during the grow, right up to the day you harvest. When you harvest, harvest the entire plant at once. Hang to dry for one week in a 70F-75F temp with lots of air movement between the hanging branches. After that week, carefully snip each bud off of the lumber and store it in tightly sealed jars, half full, laying on their sides. After the first week in the jars, carefully turn the jars to reposition the weed without touching it. Then open the jars for 3 hours in a room with fans moving the air about. Then reseal the jars tightly. Each 3 days after that, for exactly two weeks, perform that task again. Then do so at two week intervals for two months. Now your weed is dried, cured and ready to smoke. It may not be the smoothest smoke because you haven't flushed and stopped nutes until harvest day, but the additional growth of THC and calyx growth will be increased as a result. You should have close to 2 pounds of weed. It's that easy. Good luck. If you follow these instructions, you won't need luck.
