hey joeski! thanks for dropping by, yeah i can definitely recommend cfls, they're all i've really had a chance to use so far as i bought a 400w hps but it heated up my grow space to 30C+, far too hot so gave it to a friend for his tent and it worked wonders in there. but the cfls are definitely worth investing in if you're wanting to save money and reduce heat in limited grow spaces, lol quite often the case with micro grows, hence the micro part haha. anyway all the best mate keep me posted if you start any grows with them!
