You don't need to get hps or mh to grow, they will give the best results but cfls work well too and aren't expensive in the uk i can get 20watt cfls for £1 and i've seen a lot of guys here in the states that can get 42watt ones. For starting one plant you can use one of the 40watt cfls and just add two more over the next 6-8 weeks. They give off very little heat so you can get them a lot closer to your plants. Incandescents are notoriousley bad for growing and i don't know much about the infra red light you've got but i doubt you'd find many people here using them. Whats the fluro you've got? It may be that its a cfl (compact fluro light) or is it a long tube? A pic would be helpful.
