Yes, as Warlock mentioned above, you've got ample space and lights to grow 3 plants in your cabinet. Make sure you've got the inside of the cabinet lined with reflective material (not tinfoil) and be sure to install intake and out-take fans to provide ventilation. I'd definitely go with an indica dominant plant as they are better for confined spaces and have a shorter flowering time as an added bonus. Also, I would suggest mixing your light spectrum if at all possible. The orange hues of the 2700K bulbs are best suited for flowering, while the blue hues of 6400K bulbs are ideal for vegetating a plant. A mixture of the two spectrums (2/3 blue-vegetation and 2/3 orange-budding) is optimal throughout the plants life. Also, CFL bulbs don't provide the intensity to penetrate the canopy, so be sure to keep your lights as close to the canopy of your plants as possible without burning them. Luckily, CFL bulbs burn quite cool so you can have them almost touching your plants.
As for soils and nutrients, I prefer to use a soil with little to no added nutrients. Actually, I use a Multiplication Substrate which is designed for seedling and clones and contains very low levels of nutrients. I mix in sand and perlite (10%/20%) to aid in drainage and aeration. Never feed seedlings or newly rooted clones. For young plants, I use nutrients with an NPK ratio of 2-2-7. The high concentration of Potassium helps root and stem development. Once the plants have matured, I switch to 7-2-2. Vegetating plants need lots of Nitrogen to produce foliage. Finally, once the initial "stretch" of flowering has finished (approx. 2nd week of 12/12) I switch to my bloom nutes (2-7-2). During the flowering phase, a higher concentration of Phosphorus aids in bud development. Hope this helps. Good luck.
