Lighting help plz!!

Im wondering wat light i should get for a 24 plant veg area im plannin on usin a 1000 watt cool tube for flowering

Honestly it depends on a few things.

what system your going to veg in?
Is this veg room seperate from your flower room?
Do you have air conditiong in the location your going to veg in?

I used two 600w for 80plant, but my area has an a/c Co2 the whole nine yards. You could use a 600w or a 400w or even a T5 light. I would use a 400w in your position.

veg and flower are the same room and yea i will b running atleast 2 fans inside to reduce heat and the tent will be mylar

i would use a 400w that. Fans might not keep your tents fully cooled. depending on the temp of where your tent is sitting in that will have a huge inpact on the temperture inside.
