Auto flower

guys just wondering I've got a 250 watt mh and a 400 watt sodium light is it best to start autos under the light they am gonna finish under cus don't no Which one 2 start with out them 2 should I start with the lower watt power first then bump it up to 400 when I start to see flowers I've got a bud box tent 75x75x200 also got air cooled light running vi a 5inch fan run a intake fan aswell so there isn't any light leeks

Some people do the entire grow in MH. Some people also do the entire grow in HPS. This is what I've learned from my Candy Cane Autos. The MH makes them very bushy, the HPS makes them stretch. Good luck with your grow, bro.
