5x9 gorilla tent, how many cobs do I need guys?!

Hey there Milo77. Welcome to afn!

Are you planning to lite the whole 5x9 with cobs?
Thanks man!

Yes, I would like to replace the two hid hoods I have now. I'm having heat problems at the moment and I was only running them at 600 watts.
I just set someone up with the same size tent in Colorado 2 days ago. If you wanted to fill the tent you would need 15 cobs total. You could run one hps for now and add cobs to help too. This would help with the upfront cost and then you could slowely add more till you eliminated the hps.
