thanks for your help guys...

with the second set of lights wired in the temp is now stable at 26C/78F and growth of my seedling is progressing nicely. I have to be away for 4 days in about 3 weeks, so I think I'll get my bubbling bucket working. If all goes well I plan to switch to 12/12 when the side shoots start appearing on alternate sides of the stem. Doing lots of reading on forums regarding nutrient schedules and not yet decided on one. Like the idea of more light, especially as I already have a couple of extra cfl's. Junk shops this weekend for some tatty old lamps cheap!

Thanks again for your help and I'll post a photo every week so you can see how I'm getting on.:thumbsup:
