On the two lamps you mentioned....not much difference.
Get yourself some GE #F40PL/AQ Plant and Aquarium lamps for each fixture you have (they are not very expensive). These are "wide spectrum lamps". Each individual lamp is 40 watts.
They're not as good as Halide or Sodium ,but they're cheaper ,and don't get as hot ,hence reducing the ventilation reguired to keep humidity down . A CO2 generator would be a nice touch in an inclosed space ,but not required if you can get some type of air exchange to them.
Hope this helps
