Think Different sun+400w HPS

Hello everybody and welcome to this Think Different x3 grow journal, take a sit and watch them like me! My idea is to have them from 5am to 13 pm under 400w HPS, then 13-18pm under sunlight and 18-23pm again indoors. Feel free to give any advice or opinion, I expect to reach the 100g per plant and the reason I don't grow them only indoors is because here in Argentina we're getting closer to summer and it's very possible that temps get to 35°C, and 40°C+ with the 400w HPS. So why don't use the free and almighty sun? Will be glad to hear some feedback! I warn that im not an expert at english but I can manage. Will feed with organic root hormone specified above this week, now a question. Should I apply Mycorrhizae, Trichoderma and Azospirillum now or wait till they develop more roots?
