Thanks for all your advise, I have a few seeds (Samples) so I am going to try again with these and see if I do better, these cfls are giving me stress... I can get hold of 32w cfl which I think gives about 150w so X4 should be enough but I cant see what type of light it gives off, I am making up a 1m reflector from aluminium to house the cfls so this should help( I will post a pic asap, so you can tell me what you think!!!) think this is the best option as running costs are a factor... but I have to increase the yield or I might as well give up...
