how many watts?

what s the minimal amount of watts of CFL (real consumption) ,2700k would you need for flowering ,if using multiple CFL s and growin in small tent?

IMO for what its worth I like 100w per plant.

so four 40 watters would do the job honourably?

Well for the price of them more is better but 100w minimum I would deff push it to 200w if poss. Up to you to be honest.

I recommend 150w+ when using CFL's.

150 for the first plant and 75 for each additional plant
