As harshal1992 mentioned, the T5 bulbs being hi output or normal output makes a difference but for a 20 G heavy planted tank, 3x 14w bulbs puts you at just over 2watts per gallon, giving you good light for plants requiring medium low light. CO2 is very important also as it is one of the 3 key ingredients to your plants growth through photosynthesis. Pressurized is better and easier to regulate, but I have a nice DIY system that works great. Most important is the balance between fertilizer, light, and co2 you give your plants. You can't alter one beneficially without consideration to the others. Hope that helps, cheers
