Growing a normal strain along with another AutoFlower.

Would the AF strain finish under a 400w MH bulb that you're using for the vegetative phase of the non-AF strain?

Or

What would be the best plan to grow the two strains under the same light?

autos can be grown under any light and any light schedule, its just your non af will need a hps for the best flower results

I actually just got done running a similar sort of setup and I would definitely recommend keeping the autos underneath the vegging light. I say this not because of the spectrum but the light cycle, 12/12 is going to reduce the yield from your autos and any change in light schedule increases the chances of getting a hermie (very real chance with autos).

If you want to keep it simple though, they will do fine in the flower tent with the others.

it will be ok to do them together under same light my buddy did his first auto like this
