Well, most of the time it's what you put in it. Give it the proper nutes. The nutrients you give it are basically the same all the time, but the amount you give it varies on what strain you are growing. Speaking of amount, the amount of bud production is also based on your strain as well. (I.e. Big Bud yields more than Lowryder, etc.) If you are growing a plant that produces more trichomes than normal, again, the nute amount will vary depending on what specific strain you're growing. Another thing that some growers use to further trichome production is mollasses, but I've never used it before, and I'm not even sure as to what it is.


Oh yeah, and lots and lots of good lights! If you have a good light on top, that top main cola is most likely going to be one big fat nug. However, the branches on the bottom will yield less because less light gets there. You can combat this problem a multitude of ways, but I believe the best prevention method would be to have your grow in a reflective area, so a minimum of light is wasted, and more light is bounced downwards toward the bottom branches. Of course, if you have the money, you could buy two low-watt lights and lower them rather low and without a hood, so the bottom and sides of the plant can get lots of light, but I'm not sure if that's for you or not.


There's alot of ways to do so as you can tell. Most important things: Proper nutrition, lots of light, good airflow... But can you tell us what strain you're growing? :P
