Light swapping

Sup guy's n gal's

Had something on my mind today. I am entering my 4th week of flowering and what I was thinking of doing is swapping out the lights at the end of each week to try and control the grow and humidity, and strengthen up the stems.
I know there's a light with both mh and hps together, but I want to try and do it separate.
So it will go 1 week mh and the next week hps. I should be harvesting the first week of December, so I'll do that until then.
If anybody has any suggestions on how good this may or may not work, feel free to let me know.✌

plants in veg prefer the cooler light of the MH. plants in bloom prefer the warmer light of HPS. It has been found that using both MH and HPS in bloom is also very beneficial, but I don't think that using MH alone in bloom is going to be as good as the HPS. I would consider this to be less than optimal.

I know the light each stage prefers, I just want to slow the growth and strengthen the stems on one plant. Stems are long and a little skinny, but the other is fine. Plus, with my small space, they are growing like crazy lol. Its my first dwc so i didn't know. I know with mh lights, at this time, it will lessen my yield, I'm just looking for a little control. I know what to prepare for next time. ✌

have you tried a small fan to blow the plants around and strengthen the stems? I don't know that I have ever seen anyone say that one light over the other does this.

Ya I have 3 different kinds of fans, believe it or not. That's why I don't understand why my humidity is so high.
