I'm currently growing on floros but I don't think they are putting off enough light. so I "acquired" 2x 400w metal halides.

my question is.. should I use both of them, or just 1?

the room is 12.5square feet and there are 12 plants.

yes definaty use both, keep in mind electric cost and if they are not plug and play make sure u do good wire and prevent any "accident" but 2 400watt is what u need for 12 plants. not more than 12 tho. in my opinion

hey keep in mind thos lights are hot so if your plants are still babies dont put them too close to the plants. when the plants are ready for the full blast dont put the light any closer than 8 inches to the plant but, u wanna keep it as close as possible with hurting the plant

the plants are about 8 inches tall, so do you think that they are ready for the "full-blast"?

the balast says it's aproved for MH, Pulse start MH, and HPS, so i think I'm gonna invest in some HPS bulbs when they're ready for flowering.
