for best results of all do the following.....get a lighting system that has a unit/starter that can support HID bulbs (HPS&MH) from 250-400-600 watts.....
for vegetation use a 250watt MH and for flowering a 600 watt one.....
Each bulb will consume 0.25&0.6kW per hour for every hour that operate....do not use the floros for more than 2-3 weeks from seed as the plants will grow (since you talk about 10) too much and the floros will not be enough to cover their needs for light.....i go for the MH....... the only good thing about the floros is that can be placed very close to the plants.....when the plants grow too much and the floros have to move up their light will not be that strong as it was in the beggining.....plus the MH are only blue spectrum that the plants really need in the first weeks of vegetation......
