I have my veg room with 2 - 240 watt LED's - I need to buy lights for the flower room - I need to stay away from typical HID's - What size LED's should I buy for the flower (bloom) room?
I agree with Karr.
Your flowering plants ought to be bigger than the vegging ones, and should require both more space, as well as more light to fill the space.
A good rule of thumb is to double the wattage used for vegging for flowering, so in this case, 4 -240 watt LED lamps would probably be the place to start the discussion.
This, of course, assumes that
a. You're actually using the full potential of your 2 - 240 watt LED lamps in vegging, and
b. You have the space and money to put in 4 -240 watters for flowering.
If not, adjust accordingly.
