Autoflower Light Change

Hey Everybody,

Growing WW auto’s and into the 3rd week. Right now I am on a 17/7 light sch using a 600w MH.bulb. I understand to keep the light cycle the same for the entire life of the plant is best, and I intend to do just that. What about switching from MH to HPS when the flowering starts?

Thanks - Morris

I think most will recommend you change to the high pressure sodium bulb for flowering

  • good luck

Hey Morris can I ask about 7/17 that’s very unique, I don’t know if I’ve ever heard of that cycle, why did you choose that if I may ask ?

Well, lol, I set it up with security in mind. My light fires up at 5:30am and shuts off at 10:30pm. That eliminates worry about flyovers with infrared cameras. With hindsight I think I was being a little too nervous. I told my godson when he asked, that it was because of wanting good luck. I choose 2 prime numbers because I wanted to grow prime weed> :slight_smile:


BTW, Paranorman, thanks for the light information. This is my first time grow and I’m as nervous as a long tail cat in a house full of rocking chairs. :slight_smile:


That would be the best way to do it bruv…Mh for the veg period and when u start seeing buds start switch to HPS…
Since autos have such a short veg period, u can use HPS for the whole grow if u wanted/needed to…

Hope That Helped
Cheers :beers:
