Tent help 420

I useto use a 400 whatt MH bulb to veg my plants and I useto grow 4 in a 1m x1mx2m tent dunno what that is in foot. Worked fine internode spacing was very good and the blue spectrum from the MH blue kept the internode spacing very neat and tight just make sure you hang it at the correct height for whatever stage your in :) Happy cultivation. There is nothing wrong with HID lighting on the country if your country is cold enough and you have deep enough pockets to afford the electric then fill your boots they are a great bit of kit and you can get some very impressive yields from HID lighting :) and for the size of your tent that would be fine it would easily cover the 1.25 meter though a 1000 whatts would be better if you wanted to nit pick :)
