T5 use 2 sets of 4 bulbs (total
run them the long way at 18/6 for 2 weeks about 6 inches away from the canopy
600 watt after the 2nd week put in the 600 watt hps/mhd at the distance of 3 ft and use the t-5 for the egde where there is less lights from the 600 watters
1000 watts after the 4th use 1000 watters to cover 4x4 area thats make 4x8 for 2 1000 watters until the plants are cut.
Thats alot of electicity but thats how i would do it to give some tender loving care to my girls, along with proper nutes. You can actually use 1 thousand watter after the the 2 weeks of t-5 as long as you keep it at a good sistance and it should get the whole room but you would lose on the sweet spot and not distribute light evenly....like it really makes a difference if your the only one smoking it. But if not and want to be in a certain time range go with 600 watts and use your t-5 as side lights on the edge...just get to know your plants its bonding period......happy growing
