wats the best lighting for whole cycle?

ı have 10 auto plants.3 of them flowering for a week under sun light.6 of them is vegging under mh for 2 weeks also sunlight.ı see 6-7 hours sun light is not enough for flowering plants.ı will take them under the bulb with vegging plants.which lightning will be better for both vegging and flowering plants?ım thinking to use 1 day mh 1 hps..is that work well or cause stress or something bad?

because their autos that r flowering 18/6 should be fine as autos dont need the 12/12 cycle to induce flowering and 18/6 is good for veggin too

yeah dude its better to have 20/4 or 18/6.but this is not the point.which lightning will be better for both of them rest of the day wen the sun get away..this the main problem .

if to use one spectrum for full cycle id use whut i flower wit

caus it only veg's for like 3 to 4 weeks then go to flower for 5 or 6 weeks
i normally switch food when flower well under way not at first sign i guess if you really wanted to could switch light but there is no need to switch
just give plenty of light

Sounds like you wanna use one bulb. Dual spectrum HPS my friend. Get the best of both worlds.
