Would it make a difference?

If I used a 250w for 7 weeks of flower and then swap for a 400w for the last two/three weeks. Would this help pack some weight on in the last few weeks or would they still grow at the same rate as with the 250w?

Cannabis loves light. As a rule, the more the better. Your best course might very well be to use both lights all the way through (at least after the seedling stage). When in doubt, more light!

I'd use the 400 for all of the flower cycle. Scientific has it.....

I used 3 450w on my last girl because I only had 1 plant at the time. 2 at the top and one on each side. Needless to say she was a monster lol
