In a previous run I flowered under only MH. Got extreme resin production. Yield sucked.
I have since added HPS to the mix for flower. Last run I did 600w MH +150w HPS. So still more MH.
Next run I'm doing 150w HPS,600w MH, 150w HPS. So still more MH. These have always been used like this all the way thru flower.


I actually have never done an all HPS flower. I'm anticonformist or something. So I personally have no comparison other than the heavy stone and obviously crazy resin production. Screw yield focused grows anyway...

All but one of my friends flower under all HPS. The other guy has stickier bud. So do I.

The bud on my avatar is from a flo plant that was situated a little closer to the MH. U can see the difference with the naked eye.
