How much fluro power (watts) is needed for 3 plants?

I would prolly say about 300 - 350watts, the more the better tho.

 

depends what size you want to get them?
I flowered 2 ww under 200w and they were sweet

 

yea I'm curious about this too because I always here people say how much of a waste they are. I grew with two lamps or 320 watts of floros and everything worked out great. My problem is that I'm very paranoid about fire so floros seem the safest being that they give off very little heat. I don't know the size of your grow space but what i try to do is put a large lamp over the top and have two lamps mounted on either side of my plants. I do think for three plants 320 would be ideal but the more the better. Good luck

 

6 X 40 watts don't equal 240 watts total. Its just 40 watts well distributed.

Same thing with lumens.
