New grow room 10' x 7'

[Jdog7000]

I would go with 25 plants per light at the most.
20 is the normal number for a sea of green with 1 1000 watt HPS.
But 50 with 2 1000 watters will work great.
Get aircooled hoods.
Because 2 lights can make a huge heat wave in your grow room.

I plan on doing the same eventually.
I'll be doing a perpetual harvest every month.
With 2 1000 watt HPS lights.
And 20 plants per light.
