How many hps lights

[LetsGetHigh33]

How many 600w HPS bulbs would I need for 12 plants in a 2x2x2 metre tent?

Probably two, you could get away with one 1000w if you plan to keep the plants short. As you need a bit of height to get the footprint to cover. However personally i would do two 600w hps as its more efficient and gives you more play room.

Thanks for the input DanofDanger I currently have 2 hps running but 1 plants been trained for a couple months and a couple more maybe 6 weeks

and the rest are just growing normal....well a couple have also been topped and are between 3 and 5 ft in height.

i can also boost each my hps to 660w so going to leave that and boost in the last 2 weeks of flower

Sounds good
