The best way to get light to all of your leaves is to have vigorous air circulation (like in nature) not only does this move leaves constantly allowing light to penetrate the to the inner parts but strengthens the stalks (like in nature) another useful tool is a light mover. This much misunderstood and maligned system mimics the suns constant movement which also increases light distribution/penetration. I know that science hurts the brains of many noobs too lazy to read or ignorant of basic plant anatomy and physiology (how it looks and how it works), but perhaps these illustrations will help you to understand the importance of the three main processes that occur within the leaf, respiration (gas exchange), transpiration (evaporation which draws moisture up through the root system), and of course photosynthesis.
Respiration and transpiration the exchange of CO2 and O2 and control of water content. Water movement allows the plant to control its internal physiology and brings the nutrients from the soil through the roots to the plant. These are the building blocks for carbohydrates the actual chemicals required to produce those buds you so desire.
Photosynthesis which provides the ATP (energy) required for the plant to process the chemicals into complex carbohydrates.
If your head feels like it might explode then smoke a bowl and rape your plants you'll feel better in the morning. Happy Growing
