Certainly, and what I'm doing is based on some reading that said to use UV for the last two weeks of flower, but couldn't do that in a perpetual and I wanted to try it so the next best thing I could come up with was this one week per month cycle
I'm trying to find out if it will actually make any kind of difference or not, the only thing I know for sure, having grown several crops under strictly halide in the last century (I grew like this my first couple years), is that the buds seem to be tighter and there did seem to be less of a yield, maybe around 20% give or take 5%
..for me that's established, but will the ultraviolet light from mh, used on the cycle that I'm able to provide make a difference ?
I'm about to find out, harvesting the first plant grown under this cycle right now?
