hello!! I have a 1.2 sqm tent whichis 2 metre high. i have one 400w HPS in there but i am planning to grow big plants and lots of them sqashed in there. ( I have 14 plants at 5 weeks veg and now going into flower, most of them are 35-45cm tall) i guess they will become fairly tall plants. And alsoi have 30 cuttings which i will put staright into flower SOG style. BECAUSE I AM PLANNING ON GROWING FAIRLY BIG PLANTS sqashed together with dense canopy. I WAS THINKG ABOUT GETTING ANOTHER LIGHT TO ADD TO MY 400W HPS.
So i was thiing about getting another 400w and putting it sideways/ or on top, to give more light to canopy or the lower parts of plant. i was thinking of buying these 5 feet double flourescent fitting that take 2 X 55W flouro tubes. If i get 3 of these i would be adding another 330W. and i could put one on each wall sideways, so the light would be spread everywhere ? or would i be better off with another400w HPS with reflector hood and focusingthe light onto the plants wheteher it be the canopy or sideways to light up lower parts of plant??
PLEASE HELP ANYONE I NEED TO BUY LIGHTS IN 5 DAYS TIME, what should i get the flouros or the 400w HPS?

the best light you can get as far as lumen to watt output is a 600 watt hps. You'd be pushing 1000 watts but getting more light coverage and more lumens than a 1000 watt hps if you ran both of them but it's your call.
