I bought a HLG QB 135 cost me £200, that veg space is 60cm x 90cm flower 60cm X 60cm, if I started again I would buy straight from Alibaba kingbrite or Meiji, do yourself a favour buy a 240 watt quantum board, you could get a 120 or so watts but if you are serious buy a light, the light you have at the moment won't do squat, and unless your near Australia or equator it's winter, putting something in the window, well good luck with that. You could also buy spider farmer mars hydro and a few others.
