Anyone ever run both at same time with a mix of 600 hps and 400 mh from veg thru bloom? What effect on spacing, yield, etc. does it have?

I had a similar question, DaMagoMan helped me figure it out, Although my mix was a 250 w HPS and a 400w MH, Basically try it out, I'm using both of them during the vegging stage atm and my plants are growing extremely well, no sign of any unhealthy conditions, I'm very happy with it so far.. But it also could be different depending on different strains..

I use both my 430 watt and my 400 watt HPS lights for my whole grow cycle the are always on for what ever light cycle i am using

i also use 2 1000 watt switchable ballast so these are the only MH i use during the veg cycle.

And my grows turn out just fine everytime.

I see no problems in mixing the lights. Both have usable spectrums for plants in both stages of growth.
